wilkinsi Posted June 6, 2017 Share Posted June 6, 2017 The footswitch uses what looks like a six pin MIDI/DIN cable, and has 3 footswitches - channel toggle, reverb on/off and FX loop on/off. The amp doesn't have any 1/4" control jacks. I want to use my Helix to switch channels instead. Is this possible? If so, what adapter do I need?

mscbln1986 Posted June 6, 2017 Share Posted June 6, 2017 Hi there. If it is a MIDI jack, I suppose that the signal your current footswitch is sending to the amp might be simulated by the HELIX. Maybe you can connect HELIX (midi out) and amp via MIDI cable and figure out, which MIDI channel and programm change to be used. Have a look here (explanation of midi commands for RM100 amp): http://www.randallamplifiers.com/downloads/legacy/RM100%20MIDI%20guide.pdf cheers Quote Link to comment Share on other sites More sharing options...
wilkinsi Posted June 6, 2017 Author Share Posted June 6, 2017 The pins in the connector are not in the same arrangement as those on a conventional MIDI cable. They're two curved rows of 3 pins per row. Its been suggested its actually a 7 pin connection, though I can only see six. The RM100 has proper MIDI connectors, my RT50C doesn't.

cclement Posted June 6, 2017 Share Posted June 6, 2017 You need a 7pin DIN to a 1/4" breakout cable essentially. These folks might be able to help you.. they do another Randal footswitch adapter cable, so maybe they can build you one. https://btpa.com/Randall-Amp-Cables/ Quote Link to comment Share on other sites More sharing options...
wilkinsi Posted June 6, 2017 Author Share Posted June 6, 2017 Thanks for the link. I should've mentioned I live in the UK. A local music shop seems to think it wasn't possible. Quote Link to comment Share on other sites More sharing options...
