Question - FX 8 midi switching

[BobDoubleJack]

hi folks
I’m running the fx8 mk II into a jvm410hjs and have set up midi switching - it worked great at a gig last night for the first hour and a half, then either the fx8 or the amp stopped responding correctly to the stored CC commands and I had to resort to tap dancing effects and the jvm footswitch. Lead set up is 4cm, and a midi cable from the midi out to the midi in of the amp.

My question is, should I also have a midi lead going to the midi in of the fx8 and the midi out of the amp, or should one cable be enough ? Is the single cable causing the confusion? As I said, worked great for our first set, then not so much for the second.
Cheers

I only use one midi cable. midi out to in on my Mesa TC-50. Works flawlessly. I would suspect your cable might be the issue? Did it work after resetting the FX8?

Hiya, I switched it off then back on and the same issue. It worked fine for a while then started switching to different channels then not at all

If you're using MIDI control, you shouldn't also use the footswitch. This will possibly cause the default amp parameters to change and unexpected (likely opposite) things will happen when receiving MIDI commands.

Yeah, what tj said. The TC50 manual warns you to not use both a footswitch and MIDI simultaneously. I would guess its similar with the Marshall.

Thanks very much everyone, I hadn’t considered that. I’ll do a midi and footswitch program reset and start from scratch.

Thought I’d post An update, I reset all the midi programs and the footswitch programs and start from scratch , which has mainly worked in the each scene now changes to the correct channel. However, I can’t seem to toggle the clean green channel onto master vol 2. A partial success ! Haha

Another update - from partial success to relative failure !
Worked well for around an hour last night and the amp stopped responding to the switching. Bugger ! Any suggestions welcome

 

[BobDoubleJack]

Just spotted the new update , will give it a bash !

I had problems with the 410HJS using a Mk1 FX8, but a firmware update quite a while ago fixed it. I wonder if the Mk2 has had a similar issue.

Downloaded the update today so will try it out
