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; the CV ins are expanded with the included SPA expander module. Does not record samples, great for drum playback. These modules are in great shape.
