I am learning how to control a Roland A-01 using sysex and an app called MidiDesigner. I have managed to interpret the manual for values between 0-127 that only use one byte and are written as “0aaa aaaa” in the manual.
What I cannot understand is values of two bytes that control parameters with more than 128 values such as tempo (40 - 240) and pitch of each sequenced note (-1 - 127) and they are represented as two bytes of “0000 aaaa”, “0000 aaaa”.
Basically for what I have done so far, I haven’t grasped the principle. Any help would be very much appreciated as I am desperate to understand this.
