It’s working out pretty well, except that when I send a program change to call up a certain program, everything freezes.
How do you have things hooked up? What’s first in the chain? Are you using DIN MIDI?
Also, I have set up foot switches to control overall on/off, effect A on/off and effect B on/off. It works but the LEDs on the H90 only reflect the on/off status with the master on/off. Am I sending the wrong kind of messages to the H90 for the individual effects?
You won’t see the states in SELECT mode. In PERFORM mode, if you have the switches assigned to act/byp the screen tabs will reflect the state by saying either Active or Bypass and the LED buttons will light up or not.
