4 channels of soundchip-style sounds, with frequency CV control and Gate control (note on/off).
Channels 1 and 3 are square/pulse (4 MHz clock rate) with 5 preset duty cycles. Extra modulation options are 1>2 sync, 1^2 ringmod and 1^3 ringmod. Channel 4 is either a NES-triangle or one of several flavors of pitched LSFR noise.
Bonus features: 8-step sequence recorder for each channel (individually clocked by the channel's GATE input) ; input CV quantizer ; DIY MIDI interface.
These merchants probably sell this module. Huh?
