Blitz690620 Posted April 23, 2018 Share Posted April 23, 2018 Hi, Is it possible to use the built in expression pedal on the Helix to control an external device (in my case a Big Muff Pi). If possible : how is it done? Thanks, Blitz. Quote Link to comment Share on other sites More sharing options...
phil_m Posted April 23, 2018 Share Posted April 23, 2018 Does whatever version of Muff you’re using have an expression pedal input? Quote Link to comment Share on other sites More sharing options...
Blitz690620 Posted April 23, 2018 Author Share Posted April 23, 2018 Yes, there is an expression pedal input. Blitz. Quote Link to comment Share on other sites More sharing options...
phil_m Posted April 24, 2018 Share Posted April 24, 2018 With EHX pedals, the expression jack can use either a standard TRS expression pedal connection or a CV source (which the Helix has). You just need to use a TS cable with CV. Once you have a cable connected from the Helix's CV jack to the Muff's EXP jack, you can go into the Command Center on the Helix and set it up so the CV jack is tied to the either the Helix's on-board expression pedal, an external expression pedal, or a footswitch.
