I’ve been trying to get the H9, Empress Reverb and Boss ES-8 to talk to each other. I can control the Empress fine when it is plugged in o the ES-8 directly. However, when I add the H9 before it, I can’t get it to work. I have the H9 on channel 2 and the Empress on 3. The H9 works fine when connected directly to the ES-8. I have the Midi set to Thru+CC. I also tried Thru.
