I tested MFB Tanzmaus, and can confirm: it does not react to Note Off message sent by Midi from external sequencer to Kick (Logic in my case, Tanzmaus OS v1_62).
It is very disappointing, because Tanzmaus manual states otherwise: (quote)
“Tanzmaus responds to the following MIDI data: MIDI_NOTE_OFF”. Maybe with other sounds, but definitely not with Kick.
I was hoping to get similar control over Sustain Time like what is possible with Korg Volca Kick (tested too):
Why it was so important? Being able to have a Kick (or Bass Drum) with controllable sustain would eliminate need to use (expensive analogue) compressors. I produce house/techno and almost always I need my Kick’s envelope look like on the right.
I will explain why almost every good sounding house track has an envelope like on the right in another note.
