I'm finishing up a .ini file to control a Roland GP-8 (effects processor) with BCR2000. I got everything working, but I cannot get my head around how to turn each effects on/off.
The manual (http://cdn.roland.com/assets/media/pdf/GP-8_OM.pdf) explains on page 34 that the 8 effects are split into two grops each consisting of four effects. As far as I can read (and forgive me, I only started out learning of midi sysex yesterday), this gives me only two parameters to address using 4 bytes. My current problem is then that I cannot effectively turn one effect on (using a button) without influencing the other three effects within the same parameter.
Is it possible to do this in some clever way?
The Roland GP-8 is pretty simple, so I have plenty of buttons to use on the BCR meaning that I could figure out the best 'pairings' and enable these via buttons, but I wonder if there could be a more elegant solution that allows me to turn effects on/off.
I have defined my model as stated below and use the following commands to turn on a specific effect (in this case the Phaser algorithm):
00 00 | 00 - 01 | val ; Effects on - Phaser
