BitWiz as Percusive Accompaniment

Paulinko

A demo of how to use the MIDI notes for drum apps (e.g. PolyBeat and FAC Drumkit) to control BitWiz via a StreamByter script which converts the MIDI drum notes to MIDI CC. The same technique can be use with other MIDI sources and drum apps like DrumComputer for example.

Here’s the StreamByter script:

# StreamByter - Audeonic Apps
# use note input to output CC13-20 on CH1 to control BitWiz
IF LOAD
set name NoteBW
END
# assumes desired output will be CC13 through CC20 on channel 1
XX = X0 # remap everything to channel 1
# convert all note off messages to note on with 0 velocity
8X = 9X XX 00
# assign each note to one of eight CC13-20
math I0 = M1 % 8
math I0 = I0 + D
ASS M1 = I0
# convert note velocity to CC value
NX = BX

Here’s an example BitWiz script that uses eight variables x, y, a, b, m, n, u, and v.

//mirror pad synth xyabmnuv
c=(x+y+a+b+m+n+u+v)/8;
t * (x/2) | (t >> (y/16+c))
| t* (a/4) | (t >> (b/32+c))
| t* (m/8) | (t >> (n/64+c))
| t* (u/16) | (t >> (v/128+c))

Thanks, @Paulinko.

A really creative and smart use for Bitwiz.

The composition in your video sounds amazing

I will spent this week experimenting with your script!

You’re welcome. You might want to change the value for the note off values to 01 or 40 in the StreamByter script.
