4246823 - Waveshape generator for electronic musical instruments

Abstract
In a wave shape generator of the memory reading type, a waveshape memory stores sample values of a wave each value being represented by an integral address. A coefficient memory stores coefficients for nth order interpolation. Unknown intermediate sample values not stored in the wave shape memory represented by non-integral addresses and are approximated by multiplication of stored sample values of the waveshape and corresponding coefficient values on the basis of nth order interpolation. Use of the interpolation method assures smoothness of the wave shape with respect to time and thereby minimizes quantization noise while permitting use of relatively small memories.

MIDIPolis Io Jupiter 4 MIDI retrofit

http://midipolis.blogspot.com/p/manuals.html

"Io User Manual
1. Introduction
Io is a MIDI retrofit system for the Roland Jupiter 4 synthesizer. It consists of two boards that can be used either parallel or individually.
One of the boards is the Keyboard Assigner Extension and it enables MIDI control over pitch note, pitch bend, cutoff frequency, volume and portamento. It also synchronizes the arpeggio to MIDI clock and has two powerful LFOs on pitch bend and cutoff frequency. LFO settings are storable and recallable.
The other board is a complete replacement of the Jupiter's original patch programmer microprocessor with full MIDI specification and lots of functional enhancements.

"Wicks looper and Dinoaxe make noise.
You can find these noise making beasties here: http://makersmarket.com/sel..."

See the site for more. Some descriptions for the archive:

"The DinoAxe makes noise, the noise is weird.

This fun little device is a mini synth that uses two controls to make an interesting and diverse range of sounds.

The unit has two basic controls, Speed and Freq. The speed control has two functions; modulation and wobble. In Modulation mode the DinoAxe repeats the sound with a varying delay. In wobble mode the speed control varies the frequency in a sine wave pattern. The two functions are selected by rotating the speed control knob all the way counter clockwise. The Freq control varies the frequency of the sound, the first half of the control range is tones from low the high frequency, and the second part of the range is noise, noise, and more noise.

The output is via a 3.5mm stereo socket which can be plugged into earphones, a computer sound card, mixer or amplifier. I used a little vox amp in the video.

* The DinoAxe is powered by a 9v Battery which is not included due to shipping restrictions.

Happy noise making

"The Wicks Looper is a small handmade device that allows you the create real-time noise loops and sound effects.

This fun little device will allow you to build up a sound loop in real time using the tempo, sound and write controls.

The wicks looper has 3 main controls; The sound control adjusts the frequency of the tone in the first half of the dial and the level of noise in the second half of the dial, giving two distinct sounds. The second control is Tempo, which controls how fast the loop is played. Write the loop at a slow tempo then speed it up for a great effect. The third control is the write button, when pressed it writes a sound to memory which is then replayed next time the loop is run. With the sound control knob adjusted anticlockwise, you can add a rest to the loop by pressing the Write button.

The output is via a 3.5mm stereo socket which can be plugged into earphones, a computer sound card, mixer or amplifier.

* Item shipped from Australia, all prices are in US$.

* The Wicks Looper is powered by a Common 9v Battery which is not included due to shipping restrictions.

"The Wicks Looper – Acid Mix is a small handmade device that allows you the create very fast noise loops, by adding layers of sound in real time.

The wicks looper has 3 main controls; The frequency control adjusts the frequency of the noise, the first half of the range is tame, the 2nd half is uncut noise. The second control is Speed, which controls how fast the loop is played. The right hand side of this control plays the loop, forwards, turn the control to the left and the loop will play in reverse. Write the loop at a slow tempo then speed it up and reverse it, for a great effect. The third control is the write button, when pressed it writes a sound to memory which is then replayed next time the loop is run. With the Freq control knob adjusted anticlockwise, you can add a rest to the loop by pressing the Write button.

The output is via a 3.5mm stereo socket which can be plugged into earphones, a computer sound card, mixer or amplifier.

* The Wicks Looper Acid – Mix is powered by a Common 9v Battery which is not included due to shipping restrictions.

Q: What is the difference between the normal Wicks Looper and the Wicks Looper – Acid Mix?

A: The Acid Mix version plays loops about 4 times faster by making the sound played very short, it gives a ruff, out of control sound. The Acid Mix will also plays loops in reverse.

Happy noise making,

MOTM-101 Noise/Sample and Hold

via this auction

"MOTM-101 Description

'The MOTM-101 is an essential part of any synthesizer system. It is a dual-function module, where the Noise Generator is linked to the Sample/Hold section without the use of patchcords. Each section can operate independent of the other.

NOISE GENERATOR

The Noise Generator uses 2 Zener diodes to create White Noise. This White noise contains spectral harmonics from near DC to well above hearing. This type of noise is useful for simulating cymbals, ocean waves, static, and other types of "nature" sounds. It is also useful in generating random signals into the Sample & Hold, and for aperiodic, high-speed clocking.

The White Noise is low-pass filtered at approx. 2500Hz to create Pink Noise. Pink Noise is useful for lower frequency sounds such as thunder. The Pink Noise is filtered even more to generate Random Output, which can randomly modulate filters and VCOs.

These three types of noise are found on many synthesizers. However, look closely and you will see the jack labeled VIBRATO, and its associated control pot! This is a MOTM exclusive: a high-Q bandpass filter (the panel control controls the Q) that generates sine waves centered around 7Hz of random amplitudes (and slightly varying frequencies as well). On the panel, a switch selects driving the bandpass filter with either white noise or the internal/external clock from the Sample & Hold section. When the panel switch selects white noise, the vibrato output is a 'wandering' sine wave, perfect for adding realistic vibrato and tremelo. If the switch is in the clock position, each time the clock cycles the output filter rings in a dampened sine wave (the ringing amount set by the panel control). When fed to a VCO, the VCO makes a unique "bbbooooiiinnngggggg" sound.

SAMPLE & HOLD

A Sample & Hold circuit is a sort of voltage memory: each time the clock generator cycles, the signal on the INPUT jack is captured and stored on a special capacitor. This voltage is buffered and fed to the OUTPUT jack. Even with many seconds between samples, the output voltage remains nearly constant (since no circuit is perfect, the output voltage will droop, but at a miniscule rate on the order of 1mv per second). The MOTM-101 contains an internal clock oscillator, whose speed is set by the panel control. A red LED flashes at the clock rate. Plugging another clock source (VCO, LFO, etc) into the EXTERNAL jack over-rides the internal oscillator.

Again, a Sample & Hold is a part of all synthesizers....but wait! Hmmmm...what's that switch marked Track/Hold? Another MOTM exclusive! In the HOLD position, the circuit acts like a "normal" S/H: the output is held steady at the start of each clock cycle. But, in the TRACK position, the output follows (tracks) the input when the clock is low (less than 1.5 volts) and holds the output when the clock is above 1.5 volts. If you are familar with TTL digital logic, this mode is referred to as a 'transparent latch'. From a musical standpoint, this can generate more unique sounds than other S/H modules.

The SLEW control adds portamento or glide to the S&H output. It can be adjusted from zero to 10 seconds.'"

Malekko Wiard Noise Ring

via this auction

"The Noise Ring is a digital random voltage generator which can output quantised random voltages. Used at high clock rates it acts as a digital tone generator (similar to a noisy digital tone-wheel).
Additionally there´s a internal clock generator with output plus a analogue white noise source.

Technical details:
Based on a shift register, the Noise Ring processes its 8Bit information and reads them into its memory as a repetitive random sequence. Stepping thru the eight steps of this sequence is done by external or internal clock. The rate control sets the internal clock rate.
The Change potentiometer affects, if and how many new data are read into memory. the more new data the more the sequence changes.
The Chance control determines if the new data that are to be writtten into memory (derived from the noise source) rather contain "ones" or "zeroes". You can input external data, eg an oscillator (!) into the Chance Input

The random voltage outputs 1 and 2 have an amplitude of 0-10V and give quantized voltages. Either it quantizes to 1V steps (octave intervals) or 1/12V (semitone intervals).
The External Rate control randomizes the internal clock (one of the random outputs is pre-patched to the ExtRate jack), but oyu can inout other signals as well.
Clocks in audio rates make the NoiseRing play digital tones which can range also into digital noise. The Change control has a big effect on the sound character.

Inputs and outputs:
inputs: Chance CV in, Chance in, Change CV in, Clock in outputs: quantised outputs 1 & 2. Noise out, clock out

Measures and weight:
3U Eurorack module, width 14HP, depth (from back of faceplate) ~3.5cm"

Anatomy of a Drum Machine: Roland TR-909 Emulator JOMOX 09 (HQ Sound).

Published on Sep 27, 2013 massivebeatzz·58 videos

"Test, Review, Jam - SOUND CHECK. Here's something you may want to read while watching:

Built from 1997-2005 this now legendary drum box was first reviewed in June 1997 by SOS (Sound On Sound Magazine) asking: "So what do you get when you cross '80s retro with '90s know-how?"

They wrote:
XBase 09 is serious about emulating the Roland TR-909. Like the 909, it is an analog drum machine, and it sounds just like the 909, and more! It offers the same types of analog controls that the TR-808 and TR-909 did such as tuning, level, decay, snap, etc. However it provides more of these controls for more sounds than the originals ever did and has MIDI implementation and Patch memory making the XBase 09 a much more versatile machine than those originals.

Kick and snare are true analog, not emulation and not sampled. The Hihats, cymbal, ride, rimshot, claps and noise sounds are samples but are still quite tweakable. All your edited sounds can be stored into the 100 patches of memory. Use the built-in LFOs to modulate the Bass drum pitch, Snare Tune, Snare Snap, Snare Noise Tune, HiHat Tune or LFO 2.

The XBase 09's built-in sequencer is also more advanced yet faithful to the style of its mentors. Step or Real-Time programming just like it's done on the 909 and 808! However, on the XBase, any edits to the sounds will also be stored with the pattern or song! This really liven's up your beats and allows you freedom and control to do things not easily possible on the original beat boxes! There's also an extensive Shuffle mode. Of course the XBase 09 is also happy as a simple drum tone module, with all editable controls accessible using MIDI. The controls also send MIDI data when tweaked so you can record real-time edits into your external sequencer.

The XBase09′s editable controls include...
Bass drum -- TUNE (controls the pitch envelope amount), PITCH (VCO tuning parameter), DECAY (controls the decay time), HARMONICS (changes the harmonics of the VCO using a diode limiter), PULSE (square wave impulse), NOISE (clap-like sound), ATTACK (controls how much of the PULSE and NOISE mix is added), EQ (smoothes the sound with a filter).
Snare drum -- TUNE (controls the pitch of the two oscillators), NOISE TUNE (tunes the noise filter), XSNAPP (controls the proportion of noise), DECAY (noise decay time), DETUNE (detunes the two oscillators), NOISE TUNE (tunes the noise filter).
Sample section -- OH DECAY (controls the decay time of the analog volume envelope for sample assigned to OHH), CH DECAY (same but for CHH), HH BAL (controls the volume balance between the samples assigned to OH and CH), TUNE defines the playback speed (pitch) of the sample."

Noise Engineering's Desmodus Versio Goes Chameleon with Custom Firmware Support

You might remember when Noise Engineering's Desmodus Versio reverb module was announced back in August, there was this little included note: "Desmodus Versio isn’t just a reverb, though: it’s a DSP platform. Its firmware can be changed via USB, so it can be transformed into a completely different effect with new firmwares coming late 2020. Are you programming savvy? Open-source support will be released later this year."

Well, it looks like that time has arrived.

via Noise Engineering

"In August 2020, we released the Desmodus Versio, Noise Engineering’s reverb. Maybe you heard about it. We were pretty excited about a lot of things about it:

It’s a pretty kick-ass reverb.

It’s a DSP platform that users can update via USB, so we could create lots of alt firmwares for people (more on that soon. Very soon.).

It’s based on an open platform, so from the beginning, we knew we wanted to open it up so people could create their own firmwares too.

So we asked the software engineers at NE to help us less programming savvy folks talk about how this works.

First thing to note: writing custom firmware requires basic understanding of the C / C++ programming language. If you are not proficient in C / C++, there are plenty of resources or even other modular platforms to get started on!

Ok, onward.

UNDER THE HOOD - DAISY!

If you look at the back of your Versio module, you should see a mounted yellow board with a micro-USB port. This is the Daisy Seed, an embedded audio platform created by Electrosmith. It is the main processing unit on the Versio hardware, i.e., where programs are downloaded, or 'flashed.'

We opted for the Daisy platform for a lot of reasons, but the biggest was that it would be the best customer experience. At the time that the Daisy Seed became a contender for us, we had been developing, in parallel, a similar board (called George). Moving to the Daisy Seed board allowed us to speed development, decrease cost for our users, and take advantage of the large (and growing) community behind the Daisy ecosystem

Daisy is powerful and handles stereo in/stereo out with ease with up to 24-bit, 192 kHz audio processing, 64 MB SDRAM, and 8 MB of flash memory. Got an idea that you want in Eurorack? If any embedded processor can handle it, it’s probably this one."

The following is a demo by Cinematic Laboratory of the Ampla Versio, an 'all in one' VCA, VCFA, ADSR with chorus running on the Desmodus Versio.

Playlist:

1. The Bat Verb | Part 01 | Noise Engineering Desmodus Versio

I am always curious when Noise Engineering comes with something new and they never disappoint. I love reverbs. I am lucky to have the Erbe-Verb, Milky Way, Z-DSP, Clouds and ZVERB but I was pretty confident the Desmodus (Vampire Bat) Versio (Versatile) would add something new to my collection. And it did. This is just a first-patch so there will be a part 2 soon. Trust me, this video is only scratching the surface.

Note: I wrote that the DV doesn't have a High Pass filter but that's not true. It has a filter that is neutral at 12:00 and becomes high pass CW and low pass CCW. What I mean it doesn't have a filter that makes sure the very low frequencies (below 80Hz) aren't 'reverberated' (high pass) which can go totally out of control and drives the module above the digital 0dB brick wall. Digital distortion is not pretty and you should be aware of it before going live. I also need to add that it happened only once during the making of this video. Just remember that infinite reverb and ultra low frequencies can cause serious trouble that goes way beyond 'mud'.

2. The Bat Verb | Part 02 | Noise Engineering Desmodus Versio

Desmodus Versio is a reverb - with a built in delay and distortion - and lots of other cool ways to turn your room upside down and fold a cathedral. DV's first batch had a little bug (I totally missed it), but NE's been working around the clock to create a fix and roll out the 'flash your DV' website. This also shows us how easy it is to install new firmware or future applications (which are coming soon). I am not sure, but I think the code will be open source so we can write our own reverbs and FX. I'll definitely dive into that when more info is available.

3. The Bat Verb | Part 03 | Desmodus Versio + Lyra-8

I had this idea of running the Lyra-8 through the Desmodus Versio and see what would happen. Then I realized it helped me (a lot!) to tune the Lyra-8 while playing live. So this video showcases the 'beyond infinity' setting on the 'regenerate' knob, where the reverb trail just plays on forever - but you can still hear a bed of the notes you've played - and add more. It can get pretty magical.

4. The Bat Verb | Part 04 | Ampla Versio firmware | Desmodus Versio

Noise Engineering promised to bring new firmware / applications to the Desmodus Versio reverb. Because it's not a reverb, it's a platform. This means you can completely change the application inside the module. Today NE released Ampla Versio, an 'all in one' VCA, VCFA, ADSR with chorus. In stereo. And this one is a worthy addition to the 'never too many' VCA's.

5. The Bat Verb | Part 05 | Imitor Versio firmware

"Noise Engineering has just released a new firmware for the Desmodus Versio, the 'versatile imitator'. It's a twelve tap delay with tempo sync, delay timing skew, circular stereo panning, distortion, tralis that rise and fall, shimmer and harmonically related pitch shifting. POB has done an excellent walkthrough on all features (see link in video), so I'll just focus on how it sounds in various patches. the IV is also available as a dedicated module with its own faceplate, and faceplates can be ordered for your DV if you're planning on permanent use.

Please note the IV is a delay that's designed to be discovered so make sure to spend some time with it. I noticed it features a lot of sonic textures which are also found on some of the best delays around. So this one may be the droid you've been looking for in just 10 HP. Highly recommended!"

MOOG The Source

images and videos via
this auction
"The Moog Source is a monophonic microprocessor-controlled analog synthesizer manufactured by Moog Music from 1981 to 1985. The Source was Moog's first synthesizer to offer patch memory storage. The design was also the first (and only) Moog synthesizer to feature a flat-panel membrane keyboard to replace the standard buttons, knobs and sliders.

In addition to the memory capable of holding 16 presets, the Source features a 37-note keyboard, and two VCOs that can be selected between three waveforms and three octaves. Programmed presets can be saved to a cassette interface to free up the onboard memory for additional new patches. The 24dB/octave VCF has parameters for keyboard tracking, cutoff frequency, resonance, and envelope amount. There are two ADSR envelope generators that can be set in single or multi trigger modes, one for the VCF and one for the VCA. For modulation, the Source features LFO and sample and hold.

Features:
* 2-VCO
* Micro-processor-controlled
* Programmable monophonic synthesizer
* 16 memory locations
* 3-octave, 37-note (C-C) keyboard
* Arpeggiator and a digital sequencer with memory for two seqences of up to 64 notes
* First to use digital parameter access for programming, a method now commonly found in today's synthesizers, using membrane switches, a two-digit LED display and a single data knob
* VCOs have three available waveforms (sawtooth, triangle, and pulse; with pulse width modulation) and three available octaves (32', 16', and 8'). VCO2 can be detuned at fixed intervals and it can be also synced to VCO1
* Mixer section features levels for VCO1, VCO2 and Noise
* VCF (24dB/octave) has parameters for keyboard tracking (off, 1/2, and full), cutoff frequency, resonance, and contour (Moog's word for envelope) amount
* Two ADSR envelope generators, one for the VCF and one for the VCA
* Envelopes can be set in single or multi trigger modes
* LFO (triangle and square waveforms) can be routed to the VCOs and the VCF
* Sample-and-hold can be routed to the VCF
* To the left of the keyboard is the pitch bend and the modulation wheel, along with two octave-switching buttons
* These and a volume knob are the only dedicated controls.
* Back panel includes audio out, cassette interface, a recessed pitch knob (for fine tuning), and CV and S-trigger inputs and outputs
* 16 factory pre-sets are: Lead 1, Lead 2, Horn, Flute, Clav Bass, Vibes, String Bass, Harpsichord, Organ, Trill Voice, Taurus, Synthevox, Sax, Wind, Snare Drum, and Lead 1 (duplicated here so that if you wanted to, you could use this extra slot to move patches around).
* Programs are saved and loaded via a cassette interface.
* Moog's Source was their first to offer patch memory storage as well as some other new features.
* It boasted 16 memory locations so you could finally save and recall your synth patches.
* A cassette-tape jack was also implemented to transfer your patches to and from an external tape and free up the on-board memory for additional new patches.
* In an effort to modernize with the eighties, the Moog had replaced all buttons, knobs and sliders with flat-panel membrane buttons and a single data-wheel assignment format.
* Parameters are edited not with hands-on sliders and knobs but by assigning a selected parameter to the dedicated data wheel.
* Those famous monophonic Moog sounds are still inside this synth which has two fat analog oscillators and the legendary 24 dB Moog filter."

M0SS 101 DEMO video upload by Andrew March

"A quick demonstration on how to build a patch with the M0SS-101 synthesizer."

From the creator of WVR, the the M0SS 101 virtual analog monosynth is currently seeking funding on Kickstarter.

"M0SS-101 is a virtual analog monosynth built for a pure, hands-on subtractive synthesis, packed into a compact, rugged guitar pedal enclosure.

With 26 buttons and a single encoder, M0SS-101 gives you intuitive access to a deep 42-parameter virtual analog synthesis engine. Press a button to select a parameter, turn the encoder to modify it, and monitor your signal flow via the LED system.

Using a MIDI controller, you can map any parameter via simple MIDI learn, making it easy to integrate into your setup. Up to 17 presets can be saved and recalled for quick access to your favourite sounds.

The 26 RGB LEDs use colour and brightness to represent signal flow, modulation paths, settings and selections. A separate row of 11 LEDs at the bottom gives you instant visual feedback on the currently selected parameter. I aim to offer an affordable, compact, and versatile instrument, without sacrificing features, ergonomics, or most importantly, fun. I hope you'll enjoy playing this synth as much as I have :'-)"

Gotharman's zaTurn Now Available

Demos in previous postw here, also on Gotharman's here.

via Gotharman's:

"Gotharman’s has today released a new polyphonic modular synthesizer, called zaTurn. It has a number of modules, which are divided into 4 groups, to make polyphony possible. It comes with some newly designed self-oscillating 12db dual LPF/BPF analog filters." 10 zaTurn’s are currently available for pre-ordering from EUR 1709,- 10% off at www.gotharman.dk .

Additional details:

"Zaturn is a polyphonic/multi-timbral modular synthesizer with memory. All connections between modules, module settings, sequences and sample assignments can be memorized for instant recall.
Like many other Gotharman instruments, each preset contains 2 versions of the preset, that can be morphed between. With one knob, you can morph all the settings of a complete modular system!
It will also hold all your samplings and wavetables in memory, even after a power recycle.

Zaturn has a number of build-in modules, which are divided into 4 equal groups, A, B, C and D. Within each of these groups, it is possible to arrange the modules in 2 parts, so Zaturn has 8 parts in total. Each part can be trigged separately, and they have their own separate output module.
Keeping the modules in groups, made it possible to add the Favorite Sound system from SpazeDrum!

Part 1 and 2 in Group A can each be set in polyphonic mode, so that Zaturn can be up to 2 x 4 notes polyphonic. Modules in groups B, C and D can be linked to Group A, to get the same sounds on each polyphonic note, or they can be unlinked to have different sounds on each polyphonic note.

Like most other Gotharman instruments, each of the 8 parts can also just be in monophonic mode, for 8 completely separate parts.

Zaturn comes with a set of newly engineered 12 db dual self-resonating analog filters, with a special character. Each Group has one dual analog filter. These filters are arranged as LPF and BPF in parallel to each other.

8 Patch Points are also available, for inter-connection of the 4 Groups.

1024 preset, 1024 songs, 64 favorite sounds and up to 8192 samplings can be held in its internal FLASH memory.

Unlike the Anamono X, which had 2 separate bus systems, one for audio and one for modulation, Zaturn only has one bus, that handles both audio and modulation, so everything can be connected to everything.

The modules of each Group (4 groups in total):
- 2 standard Gotharman Oscillators (8 in total) - Waveforms, pitched noise, drum oscillators, samplings, wavetables.
-1 Oscillator B (4 in total) – A special oscillator with a manipulative sine wave.
-1 Noise Generator (4 in total) – While the oscillators can output pitched noise, a simple unpitched white noise generator is also available.
-1 Dual analog filter (4 in total) – 12 db LPF and BPF in parallel, with a special character.
- 1 digital filter (4 in total) - 27 filter types. Standard filters, triple filters, sharp filters, tube filters...
- 2 VCA's (8 in total) - with ADSR envelope, 16 different characteristics and a clip parameter. Can be trigged by any source.
- 2 Effects Processors (8 in total) - Many of the LD effects plus a new reverb, a wavefolder and some new pitch effects.
- 4 LFO's (16 in total) - With variable waveform and curve. Key syncable.
- 2 Envelopes (8 in total) - ADSR + decay envelope with loop options. Can be trigged by any source.
-2 Sample and Hold Generators (8 in total) .
- 1 Ring VCA (4 in total) – With several modes, like Ring Modulator, AND, XOR and Mix.
- 2 Output modules (8 in total -1 for each part) - Handles the final output level and the stereo panning."

Patch Notes #26 - Generative Eurorack Jam

Published on Nov 25, 2016 Voltage Control Lab

"Exploring a generative patch using the Ornament & Crime Turing Machine mode along with some slightly randomized drums from the Varigate and some smooth tones from the DPO and Clouds.

The Ornament & Crime is in Quantermain mode, generating a single Turing Machine on channel D, clocked by the Make Noise Tempi and Turing probability modulated by a channel on Analog Memory. Tempi is also clocking Brains and Pressure Points, one channel of the connect Analog Memory module is routed through channel 3 on Maths, and then into the Ornament & Crime CV4 input.


This is the crux of the generative voice. The slowly stepping Analog Memory switches the O&C 100% chance of a randomized value on one step, then around 5% chance on the next step, and 0% chance on the last two steps. This means every 4 bars or so, the phrase is randomized to a degree.

The generative sequence is routed to the Make Noise DPO, onto the MMG filter via the Final output and then to the Optomix. The signal is then passed through Mutable Instruments Clouds running the Parasites firmware in Oliverb mode (updated this easily via the SpektroAudio ALTRNT website), and on to the Malekko Mix4 and out. The Malekko Varigate 4 is triggering an envelope on the AD/LFO, which is opening the Optomix.


Clouds is being heavily modulated. A sine wave LFO from the TipTop Audio Z3000 is modulating the decay time control, while the triangle wave is modulating the pre-delay. The right output from Clouds is fed back into the Z3000 waveshaper input and the sine wave out from the DPO modulation oscillator is routed to the FM input as well, further complicating sine and triangle waves. The stepped and smooth random outputs from the Make Noise Wogglebug are also modulating Clouds reverb size and damping filter respectively.


Tempi is clocking and resetting the Varigate which is already triggering the generative voice. In addition, one channel is triggering the Noise Engineering Basimilus Iteritas which is acting as the snare. The BI is then passed through Mutable Instruments Warps in Parasites firmware delay mode, and out to the Mix4.


The kick and hihat are both sequenced on the Varigate as well, triggering the Roland Scooper via a few envelopes on the ADLFO.


The bass is sequenced via the DU-SEQ (clocked by Tempi), which is playing Mutable Instruments Braids. A looping envelope on the Intellijel Dual ADSR is modulating the Braids color input, giving some motion to the bass tone.
