An homage to Dennis Colin and the Aries System 300 modular synth

I’m putting together this site to share information about the development of the Alpha-Trianguli System 300 series of analog synthesizer modules. The design goal is to make a series of modules that closely match the original specs of the Aries System 300 modules.

Aries Music was a Massachusetts based company that designed and sold synthesizer module kits in the late 70’s and early 80’s. Many of the modules were designed by Dennis Colin, the famed designer of both the ARP 2600 and the multimode filter found in Tom Oberheim’s SEM modules.
