THE CMS 2607






CMS is proud to unveil for the first time, our new synthesizer the CMS 2607. We took all the features of the original ARP 2600, some circuitry from the 2500, combined them with our world famous upgrades, added more cool stuff and then squeezed it all into a 6 space rack mount heavy duty enclosure. This particular incarnation is the "2500 version" that features a beautiful heavy duty brushed aluminum front panel. We are also currently making standard versions using gray and blue paint similar to the original ARP 2600 factory color schemes.

We are currently making the prototype version for some select customers.



Additional features of the CMS 2607:

6 spaces high, yes! 10.5 inches.

Heavy duty .100 thick precision machined front panel.

Sturdy, custom designed rear enclosure.

Octave switches.

Sync switch that syncs VCO-1 to VCO-3.

VCO3 has all 4 waveforms!!!

Uses the discrete wave-shapers from the 2500 - they sound much better and produce better shaped waveforms.

Both VCO-2 and VCO-3 actually produce a sine wave, not a rounded triangle like on the 2600.

PWM on all 3 VCOs.

The famous CMS 4012 CX filter comes standard issue. Better sounding but true to the original design of the early 2600 filter.

The filter has 2 modes: CMS and ARP. The ARP mode maintains the original factory 4012 circuit. The CMS mode features the CMS 9004 dual mode filter.

The VCF has an additional High pass / Pseudo-notch out depending on the mode switch setting.

Improved AR generator circuit.

3 position time range selectors on both envelope generators.

CMS 4019CX high slew rate VCA is standard equipment.

Voltage processor 2 becomes the Post Filter Distortion circuit from the ARP Centaur when the PFD switch is engaged.

Schmitt trigger or trigger detector for externally triggering Envelopes, SH, Etc. Doubles as a distortion device.\

Separate Ring Modulator AC / DC switches facilitate a 2nd VCA.

A dedicated LFO.

S/H clock has sine out for additional LFO modulation.

Tripped out Electronic Switch has way too many uses to list here.

17 inch, 3 spring, rear mounted reverb tank w overdrive circuit.

2 pedal circuits with front panel output jacks.

Rear CV buss and Gate buss inputs.

Convenient front panel CV and Gate output jacks.

Rear mounted "slider LED disable" switch - disables the slider LEDs only.

2 1/4 inch line level outputs for stereo effects.

High quality Alps controls.

American made enclosure and printed circuit boards.

Notable similarities:

High quality Switchcraft jacks.

All critical audio processing is performed by discrete, hand selected, low noise, matched transistors.

Factory Version

The factory version has been delayed. We sincerely appreciate your patience in this matter. We also have to be honest with our customers. You may want to consider ordering the hand made version if you want a 2607 sometime soon.

Our ultimate goal is to produce an affordable factory made version of the CMS 2607. CMS is an expert service and restoration center for vintage ARP instruments. Transitioning to mass production of a complex musical instrument requires considerable re-tooling and expense.


Here is a photo of six 2607s in action in the CMS lab during a live demo recording. There are 6 2607's being controlled by 2 Roland MPU-101 four channel MIDI to CV converters.
