boyerclan6 Posted September 5, 2017 Share Posted September 5, 2017 I recently purchased the Mesa Boogie Mark V 35. Is there any way to channel switch this amp using the HELIX? I would certainly appreciate any input on this. Quote Link to comment Share on other sites More sharing options...
pilottes Posted September 5, 2017 Share Posted September 5, 2017 The only way would be a MiniAmp Gizmo with the special cable for the Mark V. That worked flawlessly for me when I had my M V. Quote Link to comment Share on other sites More sharing options...

pilottes Posted September 5, 2017 Share Posted September 5, 2017 You only use the MIDI out from the HELIX to the MIDI in of the MiniAmp Gizmo. You have 128 preset in the MiniAmp Gizmo that you can use. If I can remember, the MiniAmp Gizmo would receive a MIDI Program Change Command and pick the saved config and switch the Mark V accordingly. The saved config would include the selected Channel, the reverb state on/off and the boost (if you have that on the 35) state on/off. The config on the MiniAmp Giszo is easy to do. You press the appropriate buttons corresponding to features you want on the front, activate the write mode on the MiniAmpGizmo, send the MIDI PC by selecting the HELIX patch you want it associated. The MiniAmp Gismo will flash and thats it. Quote Link to comment Share on other sites More sharing options...
reginaldStjohn Posted September 5, 2017 Share Posted September 5, 2017 I have a Mesa Boogie V 25. I just use the cable that came with the footswitch for the amp and plugged it into the Helix Amp switch jack. I then use the control center to assign a footswitch to switch amp channels and another one to switch the EQ on and off. Works great for me and requires no extra HW.

pilottes Posted September 5, 2017 Share Posted September 5, 2017 From the MB web site they show that the two models are different in the way they implemented the footswitch. Different cable and connector. Quote Link to comment Share on other sites More sharing options...
markos7 Posted November 6, 2018 Share Posted November 6, 2018 There is the smallest midi interface for Mesa Boogie amps. http://eng.emcustom.eu/midi-interface.html Just replace original footswitch with midi interface and one midi cable and one cable from interface to amp footswitch socket. No external power needed. Quote Link to comment Share on other sites More sharing options...
