With the sound, look, and feel that started it all, the Cherry Audio/MRB VM900 Collection delivers the audio and visual experience of the legendary 1960s and 1970s-era Moog 900-series modules with spine-tingling impact and accuracy. Every detail has been expertly reproduced, for a virtual window into the halcyon days of early analog synthesis. Award-winning synth designer Mark Barton’s (MRB) proprietary DSP coding reproduces each and every sonic nuance with unprecedented accuracy.



The VM900-series designs remain true to the originals, and have not been altered or updated to reflect modern trends. Panel layouts and operation have been preserved in order to present a one-to-one early analog experience like no other. From oscillator drift to warm mixer overdrive to painstakingly reproduced panel art, it’s all there. And with 27 modules, the Cherry Audio/MRB VM900 Collection represents all of the commonly produced 900-series modules, including the early 901-style and later 921-style oscillators, both in single and “ABBB” grouped module versions. The coveted 904 ladder filter is also included in lowpass and highpass versions as well as an “ABC” combo version with the 904C Coupler module for endless filter curve flavors. The famous CP3 Mixer includes both early and later circuit styles for vintage-correct overdrive or purer tones. We’ve also included a unique Keyboard/VCO Interface module that allows three-voice chordal “paraphonic” operation and three highly-adjustable independent glides.



A classic modular system couldn't possibly be complete without the 960-series sequencer. Originally used by Klaus Schulze, Tangerine Dream, and Kraftwerk, this is the eight-stage step sequencer that set the standard, and we've replicated it exactly (along with the accompanying 962 Sequential Switch module). Actually, we added one extra feature - a 1/12 V quantized output for each sequence row, which greatly simplifies the creation of chromatic melodies.



Perhaps the star of the show is the VM1630 Frequency Shifter. Notoriously difficult to properly emulate in software and hardware, Mark Barton's advanced DSP replicates every nuance of this incredible-sounding module. From subtle vibrato, to wild phaser-like tones, to ring modulation-style alien swoops and metallic clangs, the VM1630 absolutely nails the jaw-dropping sound of this rare and desirable classic.

The Cherry Audio/MRB VM900 Collection is simply a “must-have” module set for all purveyors of vintage analog synthesis. It’s a no-brainer for existing Voltage Modular users, and for new users, it’s fully compatible with our FREE Voltage Modular Nucleus Edition, with no operational limitations. The Cherry Audio/MRB VM900 Collection for Voltage Modular includes all 27 modules, plus hundreds of presets and variations, for a fraction of the cost of a vintage Moog modular - just $79 - less than $3 per module! - and it’s available now at the Cherry Audio store! A seven-day free trial of the VM900 Collection is also available.
