Using Midi Control Changes with G-Lab GSC 3 and 2 H9

Alas, this really sounds as if you should be talking to G Lab.

The H9 Manual will tell you how to use MIDI CC to control BYPASS and TAP TEMPO, but we cannot tell you how to set up your controller to send the correct messages.

Note that there is some confusion as to whether these messages should set a state, or toggle (change) it. If this is your issue, give us full details.

Its easy to set up, but it doesnt work, I have the same configuration  using two H9’s. You have to assign one H9 MIDI channel 3 as its the one with ctrl and prog changes. Assign a program change (eg 127)on your H9 to toggle Active/Bypass and then on your GSC-3 program assign a midi prog to your switch of choice and add the ctrl change. Why it doesnt work I cant figure out. if both companies adhere to the MIDI to the standard then it should. I hoop its clear trying to explain this stuff is difficult enough

ie, On your H9 set midi recieve channel to 3 | Set “toggle Active / Bypass” to 127 in “program change recieve map” |

      on your GSC-3 select Preset of choice (say 25 for e.g) and assign it to midi channel 3  | on selected preset add change for prog 25   |  assign Ctrl number 127

For Eventides information: I have assigned  program change to 127 to test if the GSC-3 sends the program nummer and it does, so the question is why does your equipment not toggle when it recieves the signal assigned? this was not a problem with my Space bx.
