increase/decrease volume with buttons

Hi csxdy,

It's messy but it could be possible by setting things up so that pressing those buttons switches MidiBridge scenes which in turn issue a volume controller message which differs for each scene. Assuming steps of 16, that would be 8 separate scenes. Assuming 'scene channel' in MidiBridge prefs is set to 16 (we'll hijack that channel for our scenes) you'd put a variant of the following Stream Byter rules (applied to Akai SS25 Kb in port) into scenes 0 to 7:

scene 0

# convert SS25 seq buttons to volume, scene 0
B0 5A 7F = CF 07 +C # seq dn, select scene 7
B0 5B 7F = CF 01 +C # seq up, select scene 1
CF = B0 07 00 # set volume to 0 when this scene loads

scene 1:

# convert SS25 seq buttons to volume, scene 1
B0 5A 7F = CF 00 +C # seq dn, select scene 0
B0 5B 7F = CF 02 +C # seq up, select scene 2
CF = B0 07 10 # set volume to 0 when this scene loads

The numbers in bold would vary for each scene.

I haven't tried this out myself, so the above may not work straight away. Might need some tweaking, but that is the general premise. Get back to me if you need more detail or it doesn't work.

Regards, Nic.
