ADT METAHEX FM HARD SYNC UNIT

Note: Auction links are affiliate links for which the site may be compensated.

"Very rare 'Metahex' unit by the company Abstract Data (ADT)

This synth eventually became known as the 'Synthex' - full information and manual can be found on the ADT website.

This is baically a very unique FM AND Hard Sync FX unit, that allows you to insert 2 separete audio signals to modulate an internal analog oscilator (either via Fm or Hard Sync).


Controls:

'Start' - Power switch

Waveshape - controls the waveshape of the internal oscillator from square to triangle.

Pitch - controls the pitch of the internal oscillator

Sync x fade - controls the balance between the dry oscillator and the hard sync'd effect from the first input

Sync Level - volume control for Hard Sync effect

Fm X Fade - controls the balance between the dry oacillator and the FM effect from the second input

FM LEvel - volume control for FM effect

'Flip' - flips the inputs around e.g.:

Flip 'off' - input 1 = Hard Sync input _____ input 2 = FM input

Flip 'on' - input 1 = FM input ______ input 2 = Hard Sync input

'Noise' - add's analog noise to the output signal for a dirtier / grittier sound.

Please see video for demo of sounds:

Requires 12V negative tip power supply (not supplied)

Please see pictures, some of the plastic over the casing hs begun to peel off, and there are some scratches to the paint from studio use.

The unit however, works perfectly..."

Sputnik Variable Waveform Generator

pic via @Noisebug

"The Sputnik Variable Waveform Generator is a Buchla inspired discrete triangle core oscillator. One major change is the inclusion of a hard sync vs. the typical triangle core soft sync. The module features 5 dedicated audio outputs (sub, pulse, sine, saw and triangle) and various animation controls such as built-in waveshaper, saw animator and drive circuits with attenuation amount inputs. It also has a vco/lfo switch, both linear and exponential FM inputs with attenuators and very good tracking."

For those that may not know, Sputnik is Roman Filippov's (of Black Corporation) other brand.

Playlist:

1.Radical Frequencies DPVCO 1/4: overview (LMS Eurorack Expansion Project)

The Radical Frequencies Dual Precision VCO features a pair of oscillator with excellent tracking (6 octaves is the claim) that go from slow LFOs up into very high frequencies. It offers both linear and exponential FM, pulse width modulation up into the audible range, and soft sync. The advantage of having two oscillators behind one panel is that it features a lot of intelligent normalization, as well as jacks with attenuators to plug in external signals. This first movie features a demo arpeggio showing off the major features, and then demonstrates each of its waveforms and major sections:

2. Radical Frequencies DPVCO 2/4: static FM (LMS Eurorack Expansion Project)

In this second movie on the Radical Frequencies Dual Precision VCO, I focus on dialing in frequency modulation using the front panel controls, without any external envelopes or VCAs. If you’d like a demo of the differences between linear and exponential FM – and what things like waveshape and offset mean to the resulting tuning – this movie is for you. Near the end, I also demonstrate pulse width modulation, including the great sound you get when you modulate it with an audio oscillator as well. Here is a breakdown of what’s covered when in this movie:

0:46 triangle versus sine for carrier
1:04 entrainment
1:50 linear FM
6:49 exponential FM
12:11 pulse width modulation

3. Radical Frequencies DPVCO 3/4: dynamic FM (LMS Eurorack Expansion Project)

In this third movie on the Radical Frequencies Dual Precision VCO, I focus on dynamic frequency modulation where I use an external envelope and VCA to dynamically change the FM depth for each note played. I compare linear versus exponential FM, showing where linear is good for tonal and sustained sounds while exponential is good at percussion as well as adding pluck or strike to the start of each note. Here is a breakdown of what’s covered when in this movie:

4. Radical Frequencies DPVCO 4/4: soft sync (LMS Eurorack Expansion Project)

In this fourth and final movie on the Radical Frequencies Dual Precision VCO, I focus on its soft sync function. I explain how sync works, compare soft and hard sync, and play around with creating alternate timbres and glitchy enveloped sounds using soft sync. Here is a breakdown of the final movie:

The Wave Transformer // EarthQuaker's Boldest Device Yet ( & it isn't even a pedal)

video upload by Jorb

"I love a lot about this module.

Its a rock solid oscillator, which yes there are a ton of them, but this needs to be if its gonna compete. And the waveshaping from the transform circuit gives it enough of its own character to stand out.

I think its priced competitively, it does all the things other up-market "standard" oscillators do (built-in attenuators for modulation, hard and soft sync, built in sub) and it has so much of its own character.

If there's any downside, its kind of a lot of HP? But not really when you consider the sum of its parts. On all fronts, we got a banger.

Complex Morphing VCO, Subs, FM & more // The Wave Transformer by Earthquaker Devices (Eurorack Demo)
video upload by DivKid

"Well this was a surprise! Earthquaker Devices (makers of fine pedal FX) making a Eurorack oscillator. Yes they made the Afterneath module, but as that was a modular version of a pedal I didn't expect they come guns glazing with a big, bold VCO!

I first saw The Wave Transformer by Earthquaker Devices at Knobcon, where they brought it along for an early look and sat playing with it at the show I knew they were onto something that sounded great. Well now it's released here we are with a demo.

The Wave Transformer is a 20HP Eurorack oscillator, it's analog, with onboard complex, transforming wave shaping, sub generators with unique shapes, FM, sync, LOTS of precise tuning control and options to wave shape external sources, saturate audio and track subs from your other oscillators. I've had lots of fun with this one!"

Eurorack Transfiguration Oscillator
$199.00

The Wave Transformer is an analog, vintage-voiced, voltage-controlled oscillator with over 8 octaves of accurate pitch tracking. It has 7 simultaneous wave outputs, including a unique Complex output.

The Transform control morphs from a basic waveform through many strange iterations into a complex, gnarled mass of audio mutations at the Complex output. You can yield countless variations on these permutations by combining this novel circuit with Hard Sync, Soft Sync, Linear FM and Exponential FM. Additionally, you can mute the source waveform to use the circuit as a harmonic gate/VCA, rendering The Wave Transformer a voice unto itself. If that is not enough, there is a Shape Insert that allows you to transform external oscillations and modular-level audio sources."

VSL prototype CEM3340 single VCO : Demo 1

Published on Mar 25, 2019 Vintage Synthlab

"CEM3340 based single VCO, precision analog, high quality, with HS+/-, SS1/2, LIN/EXP FM, and 5 independent waveform outputs : sine, triangle, ramp, square / PWM, sub.

Price: TBD
Availability: Stay tuned via VSL social media (IG, YT, FB or vintagesynthlab.com )

In this first demo video, we illustrate just how accurate our CEM3340 VCO design is. All analog, precision trim-pots, high quality ICs, high quality film caps and 0.1% resistors used in critical circuits ...even those areas that other designs overlook!)

RANGE switch: LFO-1; LFO-2; 64', 32', 16', 8', 4', 2'

CLUTCH switch: when yellow (default) allows RANGE switch to operate freely; when red (engaged) latches RANGE switch to current selection. Switch can be rotated without affecting VCO, until released (push of the CLUTCH switch again... i.e. toggles between both modes).

HARD SYNC features: Hard Sync +, Hard Sync can be engaged independently.

SOFT SYNC features: SS1 and SS2 mode allows negative sync signal to reset VCO (tri-core). SS2 mode is weaker, however both will allow the VCO to interact in interesting ways with ext mod sources (as seen in this video demo)."

"Not Old, Not Borrowed, Not Blue...But New
In this day when it seems like so many are just resurrecting the past, we, at Artisan Electronic Instruments think art and technology have moved forward. And we want to bring something new into the world of synthesis. NUCLEUS is a unique and powerful monophonic Synthesizer that combines the sound design of East and West Coast ideas, blends Analog and Digital technologies, and packs a vast sound palette into an intuitive user aesthetic.

Don’t be fooled by its compact size. The NUCLEUS is anything but a classic remake or just a “more of the same” Synthesizer. There is a lot of sonic synthesis power hidden behind that 60hp panel, an extraordinary amount for such a small instrument.

A Beast Of Raw Sonic Power
Nucleus fills any harmonic space with its complex 3 Oscillator block. Its analog and digital circuits churn out some serious walls of sound. This little machine ROARS!

Oscillator 1 is based on an analog discrete Saw-core circuit providing those classic Saw, Triangle, and variable pulse/PWM waveforms. Tied into it is a modulate-able 4 stage wavefolder for awesome metallic tones. The Sub-Oscillator has its own variable filter producing smooth pounding sine waves or all the way through a rich square.

Oscillator 2 is also a fully discrete analog design with Saw, Variable Pulse/PWM, and PWM with Sub-Octave. But that’s just the start. It also has a selectable 2 or 3 stage Digital Ring Modulator. The DRM combines the waveforms of all three Oscillators for some amazing tones heard nowhere else. If that were not enough, Oscillator 2 can Hard-Sync to a separately controlled digital 4th oscillator. Wait, there's more, when not in Hard Sync, it can be Frequency Modulated by Oscillator 3 through a dedicated VCA controlling the FM depth in real-time.

Oscillator 3 is digital, why? To provide those unique sounds only found in the digital world. It still provides some clean anti-aliased standard shapes, like Sine and PWM but adds a few tricks, such as a variable slope Saw to Triangle wave, an adjustable width Swarm wave, and String tones using the Karplus-Strong physical model. There are ten slots for custom waveforms and a noise source. Oscillator 3 also has a bit-crusher/sample reducer effect to get into some dirty digital color.

And you can modulation just about anything! From pitch, wave-shape, and mix levels and the oscillator “special effects” of sub-shape, hard-sync frequency, FM depth, and bit crusher strength.

Character and More Character
There is so much to NUCLEUS before ever reaching the filter. But that bad boy does not want to be outdone. It is awesome in its own right. First off it offers a unique cascade multi-mode design. The filter runs in 2 pole Low Pass, Bandpass, and High Pass modes, as well as 4 pole versions of each. It’s the Dual-path Regeneration and 8-pole design that really give a unique character to the Bandpass modes, providing variable and modulate-able bandwidth and dual peak resonance. Since the filter can track over a wide range you can “play” these peaks and get a 5-oscillator sound or chord!

The filter has modulation inputs for cutoff, resonance, and filter shape. And after all that, the asymmetrical soft clipping circuits can bring in some much loved “dirt”. Just crank that Overdrive knob. Band Pass Close Up.jpg

Modulation Mania Until You Drop
With all this sonic power, the Artisan NUCLEUS Synthesizer controls it all with an deep and powerful modulation matrix. There are 50+ modulation sources and 30+ destinations that all available simultaneously. An impressive amount for such a compact mono synth. There are 4 six-stage Envelope Generators (delay, attack, hold, decay, sustain, release), with looping, linear, and expo shapes and time and sustain modulation. 3 LFOs provide 9 waveshapes, key-sync, delay, and rate modulation. 2 external CVs and 4 modulation paths from the keyboard to add more real-time modulation control. And now it gets wild. You can take those modulations sources and Add, Multiply, Average, Lag, Quantize, Switch, Sync knobs, contour, and route MIDI CC to create new modulation effects. A modulation engine that has far more on offer than a classic mono synth."

intellijel Introduces Three New Modules for Fall 2015 – µMIDI, Dixie II+, Polaris

via intellijel

"Today we are pleased to announce three new modules for Fall 2015:

µMIDI – An easy to use USB and DIN MIDI interface with clock sync and voice control outputs. Built with an ARM core for tight timing and easy firmware updates.
Dixie II+ – An expanded Dixie II with 8-position octave switch, suboctave out, a special new hard sync, and more control over FM and PWM.
Polaris – A versatile voltage controlled filter / phaser with 27 filter modes and asymmetric distortion.
Shipments are already en route to Control, Control Voltage, and Analogue Haven. The modules should be available from your other favourite retailers soon.

Watch for more exciting modules to be announced at NAMM 2016!"

"The µMIDI provides all the essentials to control and sync your Eurorack modular from your computer, iPhone/iPad, or hardware MIDI device with a minimum of fuss. No menu diving or configuration scripts, just two buttons. The connectivity, feature set, and compact size make the µMIDI ideal for integrating your modular with the rest of your rig while not taking up too much space in your case.

The upper clock section features a dedicated 16th note clock output ideal for synchronizing a Eurorack sequencer like the Metropolis. A second clock output with selectable divisions can be used when difference sync events are needed. The run and reset outputs can be used to reset your Eurorack sequencers in tandem with any external sequencer or DAW.

The lower half of the µMIDI gives you everything you need to control a single voice synth via MIDI. Just connect either a USB or DIN MIDI cable to the module, LEARN a channel, and start playing.

Future firmware updates over USB are made easy with the Firmware Updater software.

Features
High speed ARM processor for low latency & jitter.
DIN or USB MIDI input.
Two clock outputs, one with selectable divisions.
Sequencer sync via run and reset outputs.
Precision 0 – 10 V note pitch output with pitch bend & portamento CC support.
Gate and trigger outputs for envelope triggering.
Mod wheel and continuous controller outputs for additional modulation.
Firmware updates over USB."

"Dixie II+
Full-featured triangle core VCO/LFO
The Dixie II+ is a larger variant of the classic Dixie II. Using the same great triangle core oscillator, it adds a number of features to make it even more versatile with only a modest increase in size. The Dixie II+ makes a great primary oscillator for a modular system, or a great companion the Rubicon.

Features
8-position octave switch for quick setting of course tuning.
Fine tuning knob that turns to a coarse knob when in LFO mode.
Dual FM inputs, with FM1 attenuator and switch to select between exponential and linear mode.
Pulse width control with attenuator.
Reset to 0 V hard sync input, ideal for percussive sounds or modulation.
Flip sync circuit similar to but improved from the Dixie II.
6 waveform outputs: sine, triangle, zigzag, saw, pulse and suboctave."

"Polaris
Versatile Multimode VCF + Phaser
The Polaris is a 4-stage cascaded OTA filter designed by David Dixon. It’s built on the lineage of the Dr. Octature and Atlantis filters, but with a totally revised core and resonance control. Along with dedicated LP, HP and BP it outputs it features a configurable MULTI output capable of an unprecedented 27 different filter modes.

With drive turned down the Polaris is capable of buttery smooth filtering, and the cutoff control range has been fine tuned for playability. Turn up the drive and engage the multi distort asymmetric distortion circuit for a more aggressive sound. Not content to be just a filter, the Polaris’s AP phaser mode combined with frequency modulation can be used to achieve a phaser effect.

With so much versatility in a modest size, the Polaris is an ideal filter for a starter system and an excellent addition to the tonal palette of a larger modular.

Features
Dedicated LP, BP and HP outputs.
MULTI output with 27 selectable filter types: 4 x LP, 5x BP, 4 x HP, 5 x Notch, 4x AP and 4 x Phaser (AP mode with inverted dry blend).
Input drive control with soft clipping distortion.
MUTLI output asymmetric distortion."

Sync-Shift Mark II MIDI Clock Din Sync Converter Delay/Lag Offset Correction

Well that's about as convoluted as it gets. I believe this is my first title link wrap! Remember the Innerclock Sync Shift? Title link takes you to shots of one pulled via this auction. This one via polyconnect.

"Features:
'Gridlock' Midi Clock to Din Sync Conversion with ultra-low, constant conversion lag time so your initial conversion offset remains fixed and tight.

'Brick Wall' Midi Input Filter - because the Midi Specification gives no priority to Midi Clock messages we felt that in order to get the best possible I/O sync integrity we had to make sure that all midi message other than strict Midi Clock were well and truly ignored.

Innerclock Sync-Shift Mark 1 real-time Din Sync offset/lag correction lets you compensate for common hardware and software Midi Clock and Din Sync start lag time issues plus it has two full bars of Shift available so you can easily syncopate sync slave devices or software against the master.

Rotary push-pull Shift 'Fine Tune' lets you rush or drag the slave against the groove in real-time with no loss of sync. Go from hard 16th swing to phase locked grid quantize and back again all in one bar and in real-time!

'Gridlock' Din Sync to Midi Clock Conversion - same ultra-low, constant conversion lag time but reverse engineered to provide Din Sync to Midi Clock.

Modular/Discreet design - no CPU personality disorders. We could have done all three jobs on one chip with a shared instruction set but we didn't. From experience - especially where synchronisation is concerned - sharing hardware resources is a bad idea. Each of the three core components that makes up the Mark II Sync Shift has its own dedicated IC and code. This means they work great in isolation and there is no loss in performance when you connect them together.

The Mark II Sync Shift is really three separate, ultra high quality devices in one compact package where the whole truly is greater than the sum of the parts.

Hands-On. Five pots - four switched and one free turning - work collectively to provide up to two full bars of Sync offset. The top three switched pots set Quarter divisions, Sixteenth divisions and Individual Clocks respectively. The bottom left rotary switch is for Bypass, Real-Time Shift and Shift Lock. The last free turning pot provides the real-time push/pull sync fine tuning between master and slave.

All three internal components have individual rear facing Midi/Din sockets for discreet I/O.

Use the Midi Clock to Din Sync conversion on its own or simply route the converted Din Sync signal back into the Mark II for real time lag correction and syncopation of your Din Sync Slave device. Now take the Shifted Din Sync signal back in to the Din to Midi Clock converter to apply the exact same real-time lag/offset correction and syncopation method to any of your Midi Clock slave devices.

The Sync Shift Mark II provides a simple, accurate, hands-on way to make all your gear lock the way it should - Hardware or Software, Master or Slave, Midi Clock or Din Sync/+5v.

Model 15 Complex Voltage Controlled Oscillator & Model 3 LFO

via Subconscious Records

"cEvin Key and Subconscious Studios are pleased announce a limited quantity re-release of the most sought-after oscillator in the Eurorack range - the Model 15 Complex VCO - along with the Model 37 ELF LFO/Utility VCO - both built via automation in the USA, both utilizing SMT technology, new features and new graphics, yet both at an old bundled price!

The Subconscious Studios Rev. 4 Model 15 VCO maintains the identical circuitry of the original discrete triangle core to assure the waveform purity and timbral characteristics which made it a legend. It features two independent fully processed (+/-) VC inputs, a 1V/Oct input, dedicated linear FM input, hard sync, and independent Sine, Triangle, Saw, PWM and a vactrol-controlled Wave Morph outputs. Operational enhancements via it's discrete SMT component design assures even greater accuracy across all functions with stability now better than .005% (less than 2 hertz drift at 1kHz over 24 hours) and single-pot frequency range from 1 to 20Khzm, at a depth of just over .5 inches below the faceplate.

Model 15 Complex Voltage Controlled Oscillator
AVAILABLE NOW FOR PRESALE ONLY
packaged and shipped on or before Oct 15, 2011"

Formerly the Plan B Model 15 Complex VCO from Peter Grenader.

This one in via Dennis.

"Part of the the original groundbreaking ELF module series - the first to feature faceplate potentiometers on a 2cm wide format - the newly redesigned SMT Model 37 is now armed with dedicated outputs for triangle, sawtooth and square wave outputs. While maintaining it's super hard sync and adjustable FM response, the 1V/oct tracking has been increased to over five octaves, making the M37 the unparalleled cost alternative for multi-voiced modular synthesizers.

Model 37 Voltage Controlled LFO / Utility Oscillator
AVAILABLE NOW FOR PRESALE ONLY
packaged and shipped on or before Oct 15, 2011

The Subconscious Model 37 ELF LFO has an identity problem.

While specifically labeled as an LFO, it's massive frequency range 1 cycle per 30 seconds to over 20Hkz and new six-octave 1V/oct tracking range makes it the perfect candidate for utility audio VCO applications. Incorporating a heavily-modified version of the TAU triangle core architecture, the M37 is capable of 1v/oct tracking when the external VC Attenuator is set to the full clockwise position. The 3080 used in it's original core has been replaced with the 13700, a dual device which has allowed for improved response of the reset comparator, and with that enhanced tracking.

A one-shot driven hard Sync input will stop and restart the VCO dead in it's tracks with any input received. So unlike other VCOs, it doesn't require a square wave input to operate.

Further improvement are the M37's switch-selectable Saw/Tri waveform output switch which has been replaced in this new SMT generation with dedicated outputs for Triangle, Sawtooth and Square Wave outputs which are available simultaneously from dedicated output jacks. Further, the Sawtooth output has been phase-reversed so it is now a downward saw, which is widely accepted as being more useful in the low frequency spectra. When used in conjunction with the Sync input it will act as a user-triggerable decay-only envelope."

"The 7-Bit Sound NAND Drone Synth is ballistic Lo-Fi synth box that packs a heavy punch, with 4 internal gated oscillators

NAND Drone synth is easy to use and is controlled in the following ways:

· The First knob controls oscillation frequency of the number 1 oscillator that is gated to the number 2 oscillator

· The Second knob controls oscillation frequency, by turning the First switch we open or close the gate.

· The Third knob controls oscillation frequency of number 3 oscillator that is gated to number 4 output oscillator which is also gated to the number 2 oscillator

· The second switch controls the gate between number 3 and number 4 oscillator.

The Vaco Loco Zira came out of an idea to see how small a fully equipped and versatile synth could be built.

The Zira features Two oscillators, each with 48 waveforms that were favourites from the Monowave. A sub oscillator, linked to oscillator one. The Sub oscillator has a level control, oscillators one and two can be switched on or off. Note offset for Patch +/- two octaves, second oscillator has note detune of +/- two octaves and fine tune. Hard Sync of oscillator two to oscillator one's pitch.

The Zira is based on the Korg NJM2069AD Filter/VCA chip. This 4-pole low pass filter is the same filter chip used in the Poly800, DW8000, DW6000 and DSS-1

Zira comes fully assembled in a clear acrylic housing, and is a very limited edition release, never to be seen again once stocks are sold out.

Features:
· Two oscillators, each with 48 waveforms
· One Sub oscillator
· Hard Sync of oscillators
· Two ADSRs, one VCF, one VCA
· One LFO
· Multiple routing options
· 64 patch memories
· MIDI updatable firmware

Specifications:
· 2 Oscs: Each with 48 waveforms, I picked 48 of my favourites from the Monowave. A sub oscillator, linked to oscillator one. The Sub oscillator has a level control, oscillators one and two can be switched on or off.

Note offset for Patch +/- two octaves, second oscillator has note detune of +/- two octaves and fine tune.

Hard Sync of oscillator two to oscillator one's pitch.

· VCF: The Korg NJM2069AD is used in the prototypes for the filter. This 4-pole low pass filter is the same filter chip used in the Poly800, DW8000, DW6000 and DSS-1

· VCA: Very high signal to noise ratio and incredibly clean sounding, again, the prototype uses the NJM2069AD.

· EG's: One for Filter and one for VCA, both are ADSR type. They have Linear attack and exponential decay and release curves.

These go from very quick (~3mS) to a many seconds for each stage (~48 Seconds).

· LFO: The LFO has 4 wave forms, Sinewave, sawtooth, square and random. the LFO is routable to oscillator pitch, filter cut off and filter resonance.

A delay parameter allows the LFO to come "fade in" with an adjustable delay.

It also has a key sync mode, when on the LFO is forced to reset when a new key is pressed and when the LFO cycle has finished it rests at that value.

· Display: The display uses four 7 segment displays, the same as GorF and Tron.

· MIDI: MIDI CC for each parameter, receipt of Patch change (64 patches).

· I/O: The Connections could not be simpler, power in (6 to 12V DC), MIDI in and Audio out.

Cynthia Zeroscillator in Synthesizers.com Format

"Here is some info from cyndustries.com: Dr. John Chowning first described FM Synthesis technique in 1967. Since that time, no analog quadrature oscillator with through-zero capability and dynamic linear FM control has been commercially available... until now! Cyndustries is proud to announce a major breakthrough in analog VCO design, the amazing Zeroscillator. Liquid Smooth Analog Design The Zeroscillator is a full-featured electronic- music- quality analog VCO capable of linear frequency modulation through zero hertz and into negative frequencies. This makes it capable of the FM Synthesis stuff, wild and crazy sounds simply not available from traditional VCOs, and timbres not available from digital FM synthesizers. Of course, Zeroscillators also make insane LFOs! Traditional FM Synthesis oscillator implementations, such as the DX-7, are sine wave only. The Zeroscillator also makes available sawtooth, reverse saw, triangle, pulse (with PWM), and a special set of four quadrature outputs capable of unique bi-phase wave morphing, (more on that later). Look Ma'... No Aliasing! FM sounds take on their vibrant life when the amount of modulation is varied dynamically. In the analog world, this requires a special VCA to regulate the depth of frequency modulation, (often called the "modulation index"). Since this is required almost universally for Linear FM patches, the Zeroscillator has this VCA built-in. We decided however, to take this feature one extra step beyond and provide you with a four-quadrant multiplier instead of a traditional two-quadrant VCA to expand your modulation possibilities into the unexplored. The output of this multiplier is available at the panel, so you get a free ring-mod function and an interesting pick-off point for self-modulation patches called Mod Out. In addition to it's precision 10-turn tuning knob, the Zeroscillator has 1V/octave plus attenuated exponential inputs and can behave just like the VCOs you're used to. You are not forced into any specific modality and are free to use all or any subset of its 7 different modulations: 1-Exponential FM 2-Linear Through-Zero FM 3-Linear FM Dynamic Depth Modulation 4-Bi-Phasic Waveform Morphing in Quadrature 5-Pulse Width Modulation 6-Variable Sync (from none to hard synch) 7-Time Reversal The through-zero capability may be switched off which bars the oscillator from reaching into the negative frequency netherworld. If the linear modulation goes negative, the oscillator simply stops, restarting when the modulation returns to positive territory. This results in another class of sounds and is also very interesting and rhythmic when used at LFO rates. Now back to the Quadrature Outputs with Bi-phase Wave Morphing. These four outputs present the oscillator waveform at four different relative phases separated by 90 degrees (0, 90, 180, 270). If the 0 and 90 degree outputs are presented to the left and right speakers respectively, a definite stereo spread effect is obtained, and when the oscillator beats with its modulator, harmonic characteristics shift back and forth across the stereo image. This effect is unique to the Zeroscillator. Quadrature Waveform Voltage Controlled Wave Morphing in Four Phase Quadrature At LFO rates, the quadrature outputs can be used to control quad panning or create circular illusions. Remember, when the Zeroscillator is heavily FM'ed, the waveforms fold back on themselves and create patterns that look nothing like the waveforms on the label. This ain't your Daddy's oscillator! You can also morph the waveform coming from the quadrature outputs from triangle to sine to square! The 0, 180 pair and the 90, 270 pair have separate morphers which can move in tandem or opposition to each other. The morph is not simply a waveform crossfade, but a true morph which creates all the in-between waveforms in its travel and it can even be modulated at full audio rates! The morph is also constant-power which means the perceived loudness does not change as the harmonic content is being radically altered. With the morph feature, youll find yourself not needing a filter in a great many patches. We even threw in the kitchen, (Sync that is)... The Zeroscillator has Variable Synchronization from, "no sync at all... "to Totally Hard Sync". You just dial-in the right amount for your particular patch, (for classic FM type synthesis, you'll be glad you have this control on a dedicated knob). Finally, there is the mysterious "Time Reversal" Input, (which is actually what occurs when the oscillator passes into negative frequencies). Your external signal here forces the waveform to reverse its direction of travel as seen on an oscilloscope. The resulting effect is most similar to hard sync, but a completely separate circuit, and they both may be used together. Traditionally, a VCO was something that gave you a tone, a starting place from which you built your sound with other modules. The Zeroscillator however, is practically a synthesizer unto itself."
