Bastl Instruments - MicroGranny 2.4


The popular MicroGranny2 is a monophonic standalone granular sampler/sample player in miniature format. It records and can read WAV files from microsD card and processes it via granular algorithms. Adjustable parameters are start and end point of the sample as well its sample rate and bit crushing - for modulation an attack-decay envelope generator is available. Via MIDI you can control all parameters, transpose the sample or play different grains by individual notes.
The unit has an Arduino chip which can be hacked.
