Problem with MIDI in VH4

Hello!
Some time ago I bought a Diezel VH4 (2004 year of production). Unfortunately the MIDI is doesn’t working well. Sometimes working, sometimes not. Sometimes it doesn’t respond to MIDI orders. For switching I’m using TC Electronic G-system IB Modifed. Have someone has the same problem?
 
Hello!

Unfortunately this is a common issue with some MIDI devices and Diezel amps. I found that sending a sequence of MIDI PC and 'ghost' CC messages will help to ensure seemless program changing. So please check if it's possible for the G-System to send multiple MIDI PC and CC messages per preset change.

You can find more details about this in the recent Diezel service manual (page 53) where that workaround is described for the Fractal Audio Axe-Fx III.

The service manual can be found here: https://www.diezelamplification.com/support/

Best regards
