I have a problem with connecting a TC Electronics G-System to my JVM 410HJS. The way described in the manual does not work. Preset switching is not possible. The Midi channels have been matched to Ch 1 according to the manual but programming is not working. The JVM doesn't receive messages (no fast blinking). Does the G-System not send useable midi data at all?
Thank you in advance!
Sorry...This worked fine with my ES-8. Try resetting the amp to ensure it is receiving on MIDI channel 1: Hold the clean channel button while you turn the power on. The channel indicator lights will flash. Then, press the crunch channel to confirm the factory reset.
It may be the G System, but I am not familiar with that.
The JVM will respond to program change (PC) functions. You would need to create these on whatever MIDI controller you're using. Set the channel and features you would like for a given PC and arm the JVM to save by pressing the footswitch/MIDI button twice...it should then blink. While it is blinking, save the settings on the MIDI device. (You need to read how to do this on your G System manual.) A successful save will be indicated when the footswitch/MIDI button stops flashing and goes dark. Repeat this process for up to 128 total different PC presets. The JVM does default to MIDI channel 1. I don't know if that can be changed.
I hope this helps.
I am having the same problem but with my Podhd500x. I learned how to midi control the JVM channel switching and it was working with no issues for about 1 month. Then the Jvm would not change channels anymore but in the beginning it would work intermittingly. Now it doesnt change amp channels at all. I will try to reset my JVM- I didn't even know that was a possibility until reading this post. I'm so hopeful now
