ARP / Aries Mega-2600

Via CMS:

"The information on this massive integrated 2600 style synth is limited. A former ARP engineer told me that this was a side project of a ARP/Aries engineer for the Boston School of Electronic Music. It has 8 VCOs with PWM and sync jacks, 8 multimode VCFs with voltage controlled resonance, 16 VCAs with linear and exp modulation, 4 balanced modulators, 4 preamps, 4 envelope followers, 4 voltage mixers. All the circuitry is precision made on plug in vector cards with gold plated connectors. CTS pots. Spun aluminum knobs, 1/8 inch switchcraft jacks, large lambda power supply, many multiples. Custom silk screened front panel. This machine is presently being restored at CMS and will be for sale soon. Only one in existence."

This is currently on the upcoming auctions page of CMS, along with a Synthi AKS. This one in via Dave.

Update: be sure to check out the comments of this post below.

Update2: You can find the Boston School of Electronic Music website here. Based on the copyright date of 2015 - 2016, I'm guessing it launched in 2015. If anyone knows otherwise, feel free to leave a comment.

Update3: You'll find some additional info on this system and who created it here.


  1. The very same (beautiful) synth has its pic here too :
    But it is named Rivera Music Systems. Go figure...

  2. Interesting. Thanks frederic. Post updated.

  3. This is a Rivera 5000 that was owned by the late Rudiger Lorenz.
    I have a photo of it in my hands as I write this with Lorenz' handwriting on the back. He owned the synth and unless the one Phil has is the same one, there's more than one out there.

  4. ive got one too. its total crap.

  5. so is your validity

  6. It seems as though this synth has no envelope generators. :(

  7. Ron Rivera worked at Arp and designed many of the later modules for the Aries Synthesizer. Ron's company was called Rivera Music Services (RMS) and in addition to designing the Aries modules Ron designed a series of modifications and enhancements to the Arp 2600 and the mini-Moog. I haven't seen Ron in many years and didn't know that he had created this instrument.

    Ron taught a course on electronics at the Boston School of Electronic Music and I taught there as well.
