hernan93 Posted June 14, 2021 Share Posted June 14, 2021 Hello. Can anyone please, tell me if it is possible to turn on/off the wah block from my chain with the movement or "some switching" in the helix floor with the Mission L6 EP1 expression pedal connected to the Exp2 Jack? Thank you in advance. Quote Link to comment Share on other sites More sharing options...
theElevators Posted June 15, 2021 Share Posted June 15, 2021 When you connect an external pedal to your Helix Floor or LT, it becomes EXP 2. There is no way to wire the toe switch on the external pedal -- the external pedal will always be EXP 2, while the built-in pedal will always be EXP 1. On the Helix rack, it IS possible to wire the toe switch of the external pedals. If you have a missions pedal with the toe switch, that switch is useless on your Helix LT or Floor. What you can do is enable your wah-wah or any other block, when you move the EXP pedals past a certain percentage. For example, I have a song that has frequent wah-wah on/off, and I set it up that it turns on when I move my foot past 5%, and then turns off when less that 5% (heel position) after 500 ms. You can also use the EXP pedal to turn on any other effect, like envelope filter, which I also do in one song. One word of caution with external pedals: if you are planning to use the external EXP pedal instead of the built-in one, to prolong the life of the built-in one or something.... do NOT build your presets/snapshots with it connected. There is a weird bug/feature on the Helix. When you disconnect the external pedal the state of the EXP1 / EXP2 selection can be "stuck" when you switch between the snapshots and not respect the saved state of EXP1 / EXP2 inside snapshots. So basically you turn on the wah-wah, and then go to another snapshot where the wah-wah was turned off, but it still is on. This can lead to confusion on stage when you can't hear things well, and you may continue to play with your wah enabled with a harsh sound. I show the issue in my video, if you are interested: Quote Link to comment Share on other sites More sharing options...
hernan93 Posted June 15, 2021 Author Share Posted June 15, 2021 Thank you for the time to reply. I understood very well the problem and the workaround. The 3% or 5% threshold will work for me. Quote Link to comment Share on other sites More sharing options...
