Cannot record knob movements

Some sequencers / software feature a filter for removing unwanted data
from an incoming MIDI stream. "Controllers" is usually an option. The
sequencer must not filter out this data. Consult the sequencer /
software's owners manual for details. The only knobs which transmit
MIDI data on the Bass Station Keyboard are: frequency, resonance, mod
depth and env1 and env 2 attack and decay.
