I got a bit interested by the (so far vapor-ware) MOTU Volta, and its promise of synth CV control from a DC coupled soundcard. I've got a Hammerfall DSP Multiface with DC-coupled inputs/oututs myself, and figure it couldn't be too difficult to whip up a Pure Data patch to interface with my Dopefer + homebrew modules. Is it done via PWM? Has anyone successfully gotten this to work? What about recording CV?
best! D.
