I'd been waiting for my voodoolab pedal switcher and commander for quite a while until it arrived 2 days ago. I hooked them up immediately with the Damage control Time Line and Glass Nexus. but I was wandering why the commander just changed the program on the Timeline and did nothing with the Glass nexus. I was desperate. until then I read the manual and found out that the commander only send program change message to MIDI Channel 1 only. and the Glass nexus receive only Program change message channel 2. I was not used to MIDI things. so I wasn't aware with this kind of matter at the time. Now I 'm just clueless. I don't know what to do with the Glass nexus. is there any way I can utilize the Glass nexus in my rig to its maximum ability? why Voodoolab makes the commander to only compatible with Midi channel 1? is that because they want to protect their Groundcontrol pro's ability??? why damage control makes the Glass nexus only to respond only to midi chanel 2?
