Just purchased control switcher to handle channel changing duties on my dual rectifier solo 100watt head. It's three channels, and has solo boost and an fx loop, all with 1/4 inch jacks for what I thought was midi control. Unfortunately , I can't get the control switcher to properly handle the channel switching duties. If trying to use the momentary setting, the channel will switch quickly and then switch right back to the second channel, which would seem like the default channel on the amp. And in normal settings I have to constantly turn off one pot on the control switcher, then activate another. But I am worried because I am using a hd500 by line6 for external control, I can only send CC midi messages, meaning I have to consciously remember to switch to the default setting or I will have two active channels going at the same time, and possibly fry my amp. I am hoping someone can help, so I don't have to return the control switcher and sell the hd500 because of it being a pain in the ass to use while also trying to switch channels.
Thanks for any help that can be provided.
The 1/4" jacks are for external switching, either with a simple manual latching switch, or with a switch controlled by other means (ex. MIDI controlled switcher).
As you have discovered it needs to be a latching switch, not momentary.
It's not the Control Switcher's fault, you are experiencing the limitation of your HD500. I currently use a Control Switcher with a GCP to control my Mesa Dual Recto Roadster, and previously used a Behringer FCB1010 and Axess CFX4, both of which work flawlessly (using Program Change messages).
According to the HD500 Advanced Setup guide
Appendix B, pg 6 states:
"FS1 - FS8, LOOPER, TAP and EXP TOE SWITCH footswitches can each be assigned to send MIDI CC, CC Toggle, Program Change
(fixed), Bank Change (fixed) or Note On messages"
Have you tried using Program Change messages?
