When I:
- select "80s Sequencer Bass" as a preset
- hold down a few notes on on the MicroFreak
- press the "Hold" button on the MicroFreak
From what I can see, the MicroFreak sends a MIDI CC 64 message with a value of 127 when I press Hold on the MicroFreak and somehow that is setting the Filter Envelope to the Sustain value for the VCF Envelope.
Is this a an "undocumented feature"?
