just to clear things up a bit … the sysex file is ONE file, which will cointain IIRC 128 sounds.

they cannot be individually loaded into the A4 ,

before sending the sysex file, you must specify in the A4 where you want those sounds to be saved … either POOL and I recommend after the POOL into a Sound Bank (use the sound manager) …or directly into a sound bank… this is confusing as fuck at the beginning (just like anything from elektron… can you guys imagine working there =? they must kill themselves at their friday afternoon meetings :stuck_out_tongue: )
