Midi CC changes for 2 similar devices
« on: November 23, 2022, 05:35:32 AM »
I'll break down my configuration and my goal what whats happening IRL.

Config - I have two band members. I had a TC Helicon Playlive GTX that I send program changes and CC changes to using BH. I just picked up a second GTX for my partner. I'm on midi channel 1 and he's on channel 2 using USB midi (no 5 pin DIN).

My goal is to be able to send patch changes and CC changes (harmony on/off) to both units independent of each other. That way when we select a song, the correct patch is applied for each of us, and during a song, the automation controls harmony on/off so the singer doesn't have to worry about doing the pedalboard dance and constantly tuning on and off his harmonies.

What I'm seeing in real life though is a different story. The program changes are working as desired and patches are being applied as they should. No issues there at all. I can't get the CC changes to work right though. Any CC change goes to both GTX's. I have found through experimentation that CC changes are independent to Midi channels. I do see that the GTX lets me select independent midi and CC channels, where BH only allows me to specify the midi channel.

I guess my question boils down to this is there is a way to select separate CC channels (one for each GTX) in BH? Barring that, is there any way to be able send independent CCH changes to the units to control harmony toggling through the automation?

Control changes are channelized just like program changes are. The second bit in a control change string is the channel number. BandHelper builds this for you based on the channel you set on the MIDI Device page if you use the Control Change fields on the MIDI Preset page. (If you're using the Raw MIDI field instead, it would be up to you to build the hex code correctly.) You can see what data you're sending by clicking the MIDI icon in the top toolbar and looking at the Activity Log.

Thanks Arlo. As usual, you are awesome. I'll give that a shot and put in a ticket if I'm still stuck.
