Hi,
inspired by a post (in german) in the sequencer.de forum i've already planned to try something like this - when i have some spare-time. Actually planned is the use of signals from LFOs or other modular-CVs, but audio-triggers should be possible to.
I do not plan to use a AIN module at all, but a little trigger-conditioner connected to a free DIN pin or J5.
regards,
Mike
