Ok, here's V3. It sounds WAY better and behaves WAY better than V1, so forget that one and try this one please! (I had posted, then deleted, V2 but it really did need the changes I just made to this to become V3.)
This one replaces the bypass footswitch with a momentary footswitch. So now it plays normally, use any amp you want etc... but when you want to trigger the effect you hold down the BOTTOM left footswitch (It's currently called "Position" which I tried changing the text for, but it changed back.... you get the idea though).
You have to hold teh footswtich down WHILE you play teh chord (like, before), for feedback to trigger, and keep holding it to get the feedback, although if the signal is strong enough and you have the compressor pedal on then it might still trigger if you play a note and then hold down the pedal. When you let go, feedback stops, although it'll stop itself when guitar volume fades enough from strings just fading as they do. It's not real feedback after all! I did add a reverb in the freqout path at the end, which you could bypass or edit of you like, cuz the way the feedback ends was so abrupt that I hated it, and the reverb adds a messy end to it that just sounds more like a real amp's feedback ending, to me.
I also turned up the sensitivity of the feedback and the volume of the feedback when enabled, since mistriggers aren't likely now due to you being able to let go of the pedal when you are playing normally.
Note that I purposely eq'd down the higher strings and higher notes on the guitar within the feedback trigger path (not in the regular guitar sound, don't worry), so higher guitar strings and notes don't do any feedback, because they don't feedback in real life as much as the low ones, and when they do they should feedback the real note, not an octave higher, which will be a much more complicated (maybe impossible with helix) task....(cuz I'd need to have two feedback systems, one for regular notes, one for octave notes, and so on.... ugh... but even the real freqout pedal doesn't do that)
I also added a compressor, tube screamer, and increased the amp gain, and all effects have foot switches now. I suppose I should add volume pedal and wah pedal too... I'll add that another day.
I reversed the paths so it's like this now: comp, freqout, screamer, amp, cab, reverb.
This one, to me, is really good sounding and actually useful! I sorta wish it would trigger reliably by hitting pedal without having to replace your chord, but whatever, this is good enough for now.
