Hi all, I'm a vocalist/guitarist using midi files.. I'm looking for a sysex solution for my roland sc8850. The global reverb level is 40 and I would like to turn it off, or reduce it on channel 2 only. I use channel 2 for the bass and usually have CC91 set around 10. Using sysex I have switched on the effects for this channel only and selecting the compressor to try and improve my bass sound. By doing this, its not responding to CC91 set at zero and the reverb is too much at a level of 40. (paging down within the compressor window, the reverb level is at 40). I think what i'm looking for is an Effect to Reverb level set around 10..or off completely. Can this be achievable by a sysex message or even a LSB or MSB setting? I have studied the manual from front to back but I just can't see it. Any advice would be well appreciated..
