"Dave Smith Instruments Ships DSM01 Curtis Filter Module

Acclaimed Synth Designer’s First-Ever Product for Modular Systems Now Available

San Francisco, CA—August 28, 2014—Dave Smith Instruments today began shipping the DSM01 Curtis Filter module, their first product for modular synthesizers. The module takes its name from the filter chip originally designed by the late Doug Curtis, which has been an integral part of the sound of Dave Smith’s instruments from the classic Sequential Circuits Prophet-5, all the way up to recent synths such as the Evolver, Mopho, Prophet ʼ08, and Prophet 12.

The DSM01 features a switchable 2/4-pole, resonant low-pass filter, as well as its own VCA. It is a standard 8HP wide, Eurorack-format device with interconnections made using 3.5 mm phone jacks. A carefully designed set of inputs and parameters allows voltage control of filter frequency and resonance. Filter slope is selectable between -12 dB and -24 dB. The module’s VCA features two separate outputs for the filter—one pre-VCA and the other, post-VCA. A unique feature of the filter is a Boost function that introduces harmonic distortion into the signal for more aggressive coloration.

“Having the widest tonal palette possible has always been the goal for modular users,” said Smith. “This product is our first—but significant—contribution to that world. We wanted to give modular users easy, affordable access to the classic Curtis filter sound, which I’ve always found very versatile and expressive.” The Curtis sound has often been described as saturated, brash, and powerful, and has also been fundamental to such vintage instruments as the Oberheim Xpander, Rhodes Chroma and Polaris, and Elka Synthex.

“The DSM01 packs a lot of sound-shaping power into a small package. We think modular users are going to get a lot of sonic mileage out of it,” said Smith.

The DSM01 Curtis Filter module is available now with a MAP of $179."

Moog System 1 custom 55/35 modular 3C - £25,000

The ultimate modular synthesizer. Originally conceived by Dr Robert A. Moog in the mid sixties as a less bulky, more affordable alternative to the famous experimental RCA Mark 2 (which filled several rooms), it became the instrument that made synthesized music popular, especially thanks to Walter Carlos' album "Switched On Bach", a massive hit in 1968. Other artists, like Tangerine Dream, Klaus Schulze and Emerson, Lake & Palmer also explored the possibilities of the Moog in mainstream music and even used it for live performances. But the modular systems were generally too complex and expensive for most musicians, designed as they were for studio composition of electronic music, and Moog went on to produce more performance oriented instruments such as the brilliant Minimoog.


System 1 consists of 2 cabinets.

"One Voice to Rule Them All
Dave Smith calls the Pro 2 his 'most powerful mono synth ever.' It shares the same exceptional ergonomics and playability as its 12-voice sibling, the Prophet 12, but carves out distinctly different sonic territory with an all-new dual analog filter architecture, a monster step sequencer, superwaves, digital bucket-brigade delay, and a lot more. Nothing else sounds like it and nothing else performs like it. The Pro 2 raises the bar for mono synths and redefines the word 'fat.'

A New Classic for a New Generation
The Pro 2 is a fusion of classic analog synthesizer design and cutting-edge digital technology. It boasts four high-resolution digital oscillators, plus a sub oscillator. The oscillators produce both classic and complex wave shapes and can frequency and amplitude modulate each other in any operator and modulator configurations you choose for harmonically-rich FM and AM sounds. A set of Character controls adds high and low frequency boost, bit and sample rate reduction, and tape saturation emulation to the Pro 2's sonic palette.

Two New Filters Based On Vintage Designs
At the heart of the Pro 2's gutsy sound is its all-new dual filter design. Filter 1 is a 4-pole low-pass design inspired by the original Prophet-5 filter. Filter 2 is a state-variable design inspired by the Oberheim SEM and can be continuously varied between low-pass, notch, and high-pass operation, with an optional band-pass mode. The two filters function in either serial or parallel, or anywhere in between. Two of the four oscillators can be routed through Filter 1 with the other two routed through Filter 2 for a broad range of tonal possibilities.

Advanced Sequencing
One of the most exciting features of the Pro 2 is its sequencer—possibly the most powerful step sequencer ever designed for a synth. With up to 32 steps and 16 tracks, it provides real-time input, rests, and variable-length sequences. It also syncs to MIDI clock and external audio input. Sequence tracks can control any parameter in the Pro 2's extensive modulation matrix.

Plays Well With Modulars
The Pro 2's flexible architecture opens the door to not only processing external audio, but also to interfacing with modular synths through its 4 rear-panel control voltage inputs and outputs and a dedicated gate output. Control voltages can be assigned and routed from within the modulation matrix and can run at audio rates for extreme modulation effects. Some of the many parameters that can be sent to the CV outputs include oscillators, LFOs, envelopes, and sequencer tracks, making the Pro 2 a natural choice for the center of your studio or live setup.

Delays, Envelopes, LFOs, Arpeggiator, and a Multitude of Modulation
The Pro 2's delay section provides three digital delays with pan, and high-pass and low-pass filtering controls. A fourth delay is a digital bucket-brigade delay (BBD) for analog-style effects. There are four loopable five-stage envelope generators, four syncable LFOs with slew and phase offset, a full-featured arpeggiator, and a sixteen slot modulation matrix with dozens of modulation sources and destinations.

Monophonic by Design, Paraphonic by Choice
The Pro 2 was designed primarily as a super-powerful monosynth, but it’s also a true, four-voice paraphonic synth that allows you to control each of its four oscillators individually with their own envelope. This makes playing four-note chords not only possible, but very expressive.

Package all of this power in a three-and-a-half octave, semi-weighted keyboard with velocity and channel aftertouch, add two backlit pitch and mod wheels and two location and pressure sensitive touch sliders, and you've got one of the most feature-rich, awe-inspiring synthesizers ever created."

Dave Smith Instruments Introduces DSM03 Feedback Module

via Dave Smith Instruments

"Third Eurorack Module for Modular Systems Now Available from Acclaimed Synth Designer

San Francisco, CA—October 13, 2016—Dave Smith Instruments today introduced the DSM03 Feedback Module, their third offering for modular synthesizers. At the heart of the Eurorack-format module is a tuned feedback line with adjustable parameters for Amount and Tuning. It also features a newly-designed, resonant, low-pass filter for further signal processing. A noise source is also provided with Trigger In as well as Attack and Decay envelope controls to allow Karplus-Strong-type plucked string synthesis.

According to Dave Smith: “We adapted the feedback feature originally found in our Evolver, Pro 2, and Prophet 12 synths. The idea is that you have a tuned feedback loop that takes the audio output, runs it back through the filter, then through a delay line so you can perform Karplus-Strong synthesis—or just use it for mangling sounds.”
With regard to the filter, Smith added: “The 4-pole, resonant, lowpass filter is a new digital design, based partially on classic analog filters of the past, but with over-sampling and numerous tweaks in the signal path. There was no attempt to copy or duplicate a specific, existing filter. We simply wanted to provide a great-sounding design that works well both in the feedback context and as a stand-alone tone-shaping tool.”

The DSM03 module is a 10HP wide, standard Eurorack-format device with interconnections made using 3.5 mm phone jacks. A set of inputs allow individual voltage control of feedback amount, tuning, low-pass filter frequency, and filter resonance. The module provides one audio input and one audio output as well as an audio trigger input for the noise source. The digital filter’s signal path provides full 24-bit, 96 kHz resolution for superior audio fidelity.

Said Smith: “When it comes to designing our modules, we like to provide things that are slightly esoteric, but still fundamental to the Dave Smith sound. Tuned feedback has been a part of the tonal palette of our synthesizers since the Evolver, so we wanted modular users to have access to it, too. It offers a lot of really fun, creative possibilites.”

The DSM03 module is available now with a MAP of $275."

Prophet '08 Soft Strings

Published on Oct 9, 2017 Sacred Synthesis

"I've been focusing on the Poly Evolvers for a full nine months now. I deliberately did so while the Prophet Rev2 fervor was at its height, and now that it's slowly passing, I thought I'd return to the Prophet '08.

Somewhat in imitation of the 'Soft Strings' piece I did on the Prophet 12, I thought I'd begin with the Prophet '08's version of the same patch. This sound uses the usual Keyboard-Module pairing and panning at the mixer for stereo breadth and depth. Only one keyboard was used, and every note is Prophet '08 except the bass, which is, as usual, the Evolver Desktop controlled by the Hammond Pedalboard.

By the way, the photographs used throughout this channel were all taken by my wife. These are the glorious local places that we weekly walk or hike in western Massachusetts. The present picture was taken just this afternoon, on a humid drizzly Columbus Day, as the remnants of the hurricane "Nate" passed through the area.

PRO ONE vs. PRO 12: analog vs. digital Prophet 5 - Harlem Nights

YouTube via harlemnightsmusic | September 26, 2010

"An analog versus a digital voice test of the Sequential Prophet 5 (rev 3) synthesizer (1978):
- L channel = Sequential Pro One synth (1981)
- R channel = Creamware Pro 12 synth module (2006), in single voice mode

Mostly focusing on basic sonic quality, not features. Envelopes and filter levels were matched to eachother by ear (the number settings differ). Pro 12 was played with EMU Xboard 61. No added fx or EQ. Both were recorded through the same mixer and soundcard.

There's quite a lack of proper Pro 12 demos on internet, hence I made this one for others deciding about it... A HQ mp3 of the test can be found at: www.harlemnightsmusic.com/PRO_ONE_VS_PRO­_12.mp3

To my ears, the Pro 12 held up surprisingly well in this test against a famous analog bass synth. Main sonic differences were in the filter and pulse width range. I would say the basic sound

In a polyphony test, against a real Prophet 5, this difference may be larger, as the oscillators will be summed. But if you play the Pro 12 in two voice unison with a slight detuning, you still got six phat voices and won't be far off :-)

Next time: more music!

Enjoy

Dave Smith Instruments Tetra

via Dave Smith Instruments
"•Affordable, fully programmable poly synth with a 100% analog signal path.
•Classic, real analog sound—including legendary Curtis analog low-pass filter.
•Four-part multitimbral capability with four separate outputs.
•Combo Mode for huge unison patches, stacked sequences, and "modular-style" poly sounds.
•Expandable: poly chain with other Tetras, Prophet '08, and Mopho for expanded polyphony
•Just 7.9" x 5" (20.07 cm x 12.7 cm).
•Free editor for Mac OS and Windows.
Overview
Tetra is our next-generation analog poly synth. Tetra takes the award-winning sound and features of Mopho, multiplies them by four, and packs them in a box less than half an inch larger!

Tetra has multiple personalities. It is a four-voice, analog poly synth, a sort of “mini Prophet.” It's a four-part, multitimbral synth with separate outputs, essentially four Mophos in one very compact box. And it’s a voice expander for other Tetras or the Prophet ’08.

Outside the Box
Physically, Tetra is similar to Mopho, with four assignable parameter controls per program and a row of controls dedicated to the most commonly used performance parameters. All of the parameters can be accessed from the front panel and Tetra is fully programmable. A free, downloadable editor is available for Mac OS and Windows to facilitate more comprehensive tweaking.

Most of the rotary controls are detented encoders, but Cutoff and Resonance are potentiometers, allowing full sweeps with a single turn. The Push It button is a manual trigger to play notes and latch sequences on without the need for a MIDI controller.

Audio is output in mono, stereo, or per voice, via the four audio output jacks. There is also a headphone out. MIDI communication is by standard MIDI in and out jacks or USB. Poly Chain Out is a special, dedicated MIDI output to chain multiple instruments for increased polyphony.

Under the Hood
The voice architecture is based on the Prophet '08, but with the addition of a sub-octave generator for each oscillator and a fully programmable feedback loop for each voice. That breaks down to two DCOs, a resonant low-pass filter, three DADSR envelope generators, four LFOS, deep modulation routing, an arpeggiator, and a 16 x 4 analog-style step sequencer per voice. Feedback is capable of producing effects ranging from mild distortion to fairly extreme harmonic instability. (That's a good thing.) The possibilities are nearly endless. And the audio signal path is 100% analog.

Tetra a la Mode
In Program Mode, Tetra is a four-voice, polyphonic synthesizer with four banks of 128 programs. As with the Prophet '08, each program contains two layers—each layer is essentially a separate patch—that can be used to create keyboard splits or stacked sounds. Banks 1 and 2 are the Prophet '08 factory programs; banks 3 and 4 are a combination of Mopho and new programs.

In Combo Mode, a different program can be assigned to each of the four voices. Combos can be used for mammoth unison patches or for triggering up to four different 16 x 4 sequences—each with its own program—simultaneously. Combos can also be used to create "modular-style" polyphonic patches, where each voice plays a different program, with a slight variation on the same sound or even a drastically different sound.

In Multi Mode, Tetra becomes a multitimbral sound module capable of playing four monophonic parts on four MIDI channels, with separate outputs for each voice. Coupled with a MIDI sequencer and DAW, Tetra can play complex arrangements or analog drum parts with each part individually processed and recorded to its own track.

This One Goes to 12...and 16
Up to four Tetras can be poly chained for eight, twelve, or sixteen voices total. When used with a Prophet '08, up to two Tetras can be poly chained for a maximum of sixteen voices. In addition, the Prophet's front panel controls map directly to almost all of Tetra's parameters, so the Prophet acts as a programmer and control surface. And a Mopho can be connected to Tetra's Poly Chain Out for five-voice operation."

Playlist:
1. Oberheim OB-X - Rosen Sound Demo

The OBX was the first major "answer" to the Prophet 5 synthesizer, and at least in our opinion, was the best answer anyone could've given.

The OB-X is based on the basic design of the (S)ynthesizer (E)xpander (M)odule also from Oberheim. Like the SEM, it features two discreet VCO's with saw and pulse, two envelopes, and the low pass section of the SEM filter. It also added noise, a release control, and cross modulation (similar to the Prophet's cross mod). The prophet's cross mod was a bit more dynamic, though. A flexible LFO section is also featured.

None the less, the OBX is in a species all of it's own in many ways. It's one of the very few mostly discreet programmable polyphonic synthesizers, and more than that spec, it sounds unique and absolutely marvelous.

Our unit features encore midi

Book your rental package with Rosen Sound and see the rest of our synth catalog at www.rosensound.com/rentals

2. Moog Minimoog - Rosen Sound Demo

3.SCI Prophet 5 - Rosen Sound Demo

In a lot of ways this needs no introduction. One of the most iconic poly synths ever made, and the first synth to offer true programmability with polyphonic architecture.

The Prophet 5 offers your basic amenities in a poly synth with 5 voices each with 2 VCO's, a low pass VCF, a VCA, two EG's, one LFO with multiple wave shapes available, with POLY MOD as the icing on the cake. This lets you make FM type sounds and is part of what makes the prophet 5 unique.

Our unit features factory midi

4. Oberheim Four Voice - Rosen Sound Demo

This in our opinion is one of the finest synthesizers ever made in terms of overall sound. The features are of course many and the synth as a whole is very flexible and powerful, but the sound it outputs is nothing short of mesmerizing.

The FVS features 4 Synthesizer Expander Modules (SEM) each representing a polyphonic voice. This means for one patch, each SEM must be setup identically. This may seem like too much, but it's actually a very enjoyable process that causes you to think different about the patch your making, the polarity of your modulation per voice, and subtle differences you can set.

The synth can also be used in a powerful unison mode, allowing each SEM to be adjusted separately for a crazy 4x dual oscillator synthesizer each with a multi mode filter to be fired at once.

Each SEM is as or more powerful than your standard mono synth, featuring 2 oscillators with saw and pulse each, PWM, FM, 1 LFO, two EG's, a bi-polar filter modulation control, and the sweetest Oberheim filter ever made featuring a bandpass filter and a sweepable LP-HP filter. These filters are special in the way that when the resonance is turned up, there is no loss of volume or low end.

Additionally, our FVS is an early model with no programmer (a feature loathed by many anyway). Instead, it features 2 dual mini sequencers with a common clock available. This means you can do 8-step 4 note poly sequencing between the four SEM's, or split the keyboard with one sequencer playing 1 SEM and 3 note chords on the other side of the keyboard.

Functionally, our FVS is very much in tune and has been stabilized to survive travel and tuning consistency. It is in tune as soon as it's turned on, and we provide a quick start guide for our rental customers to learn how to easily program and tune the machine.

Our FVS also features MIDI in via a modified YARN's module installed inside. This allows through basic midi and if desired (more complicated) midi scripts to play it polyphonically (default on boot), sequence each SEM assigned to a separate channel (enabling MPE), or played in Unison. All of these features can be harnessed by utilizing SYSEX or the Yarns editor, all which is provided on a thumb drive for rentals.

5. Moog Memorymoog - Rosen Sound Demo

To start, let's forget the internet-lore or an "unreliable" and "impossible to tune" machine. Our service shop is known worldwide for our work on Memorymoogs and stabilizing them for real production use.

Now, let's introduce you to (what we consider) the pinnacle of Moog synthesizers. With 3 oscillators + ladder filter per voice, flexible and intuitive modulation, and a knob per function, the Memorymoog is not a force to be reckoned with, and is in what we consider to be the top 3 best sounding synthesizers ever made.

From lush pads, 18 oscillator unison leads, heavy bass, and even gentle timbres, the memorymoog is sure to be a staple piece for your session in any genre on music. Plus it has everyones favorite feature: an arpeggiator!

Our rental memorymoog will arrive with an expression pedal and 12 custom patches (87-99) made by our resident in house programmer, Eli Goss. These 12 patches are the juice that will fuel modern productions to achieve sounds unobtainable by any other synth, with plugins not even worth a mention.

6. Oberheim OB8 - Rosen Sound Demo

One of our staple synths in the collection. The lore of the OB8 is that it's a less-exciting OBXa, however, with some choice mod's which we've done to ours, they are sonically identical.

The OB8 is one of the most flexible synthesizers available, which includes deep LFO routing from the front panel, and a PAGE 2 function that transforms every knob and button on the synth to do even deeper modulation, including quantized LFO's, musical "OBXA" style detuning, envelope routing, and more.

Additionally, our OB8 has been fitted with a Pratt & Read keybed, which brings the true feel of American poly synths to the experience, while also having the amenities provided by the B5 EPROM including factory midi.

7. Sequential Circuits Prophet 10 - Rosen Sound Demo

The Prophet 10 is more than just 2 Prophet 5's in one box; featuring an active EQ per voice, deeper modulation, and more performance capabilities with it's dual manuals and CV pedal inputs. This prophet 10 also features midi in and out.

8. Oberheim Four Voice Sequence

You could do an entire score with this #oberheimfourvoice. With quad poly sequencing and split modes the sky is the limit. Available for rent through us! Contact us for rates and availability. And yes, it has midi!
