Could anyone please help me out. How do you tell your sequencer program(I use cakewalk) to transmit system exclusive mesage (for instance: change cutoff frequency) to your midi synth. (I've menaged to record this information from JX-8P to cakewalk and now It's saved in sysex wiew, but I don't know how to activate this thing back to the JX-8P.) I'm dealing with this for about a week and I'm getting really frustrated. I've even dreamt about it. Really! Thanks for help!!!
