Free Minimoog Model D Software Synth For Linux, Mac + Windows
Idle Foundry has released CA-72, a free software synthesizer modeled on the published circuit of the Minimoog Model D (c. 1972–73).
Every board was transcribed from the original service documents into SPICE netlists and simulated in ngspice. The real-time model was derived from those simulations and tested against them, factory calibration included.
Features:
- POLY: a whole instrument for every note, up to ten voices
- ENTROPY: every voice built from its own batch of parts
- SPREAD: the voices across the stereo field
- FEEDBACK: the phones-to-input overdrive trick, built in
- VST3 and CLAP · macOS, Windows and Linux
- Free and open source (GPL-3.0)
CA-72 is available now as a free download.
