fb 4 notes
visual feedback of table data for bidirectional midi-controllers (f.i. novation launchpad,livid base). 4 elements of a table are mapped to midi - notes.
Inlets
int32 offset in the table
int32 velocity on modulation
bool32.rising redraw
Outlets
None
Parameters
int32.mini map the step to midi notes
int32.mini map the step to midi notes
int32.mini map the step to midi notes
int32.mini map the step to midi notes
int32 note velocity if step > 0
int32 note velocity if step <= 0
