This module is basically Bastl's popular MicroGranny in a Eurorack module. It has an SD card for holding samples with two channels that choke each other due to monophonic playback. There are start and end controls, grain sweep, attack and decay, and sample rate/crunch parameters. There is one CV in, assignable to any parameter(CV ins can be expanded with the optional SPA expander module). Does not record samples, great for drum playback. This module is in good shape with just a little bit of wear.
