copperfield? the magician? because it would take magic to do such crazy things?

Well one thing that would be really cool would being able to somehow pitch shift frozen parts. Because it’s really fun to arpeggiate and sort of use the freeze to have an organ forming a bass line, but if I want to go into a heavier part from that, sometimes it isn’t ideal just to unfreeze and let the pitch shifter follow you. I’d sort of like to be able to take that frozen part to “11” with me if you sort of know what I mean.

Also maybe being able to choose the functions of the 2 secondary buttons. So that if I’m not using the expression button, I could use it to scroll through expression modes. If those switches had assignable functions it could really open up a lot of new possibilities. Perhaps one of the assignable functions could be a special option for different expression modes- turn on an LFO in addition to the expression, allow for pitch shifting of frozen parts, etc.

Other things- if there was a little flip switch above the envelope control to change between filter and volume, separate attack and decay controls, etc.

An FX loop would be cool as well

or a PWM expression mode even (if that’s even possible)

being able to choose whether a voice will be effected by the expression pedal or not, so you could pitch shift only one voice if wanted

Or even just a plain add on pedal for the HOG
4 jacks
-expression in (plug your expression pedal into)
-instrument in (for the envelope)
-instrument out
-expression out (to plug into the HOG expression in)
3 modes: step sequencer, envelope (slow and fast like on the Polyphase), and LFO
when bypassed, you use your expression pedal as normal
when not bypassed, you can choose between having a step sequencer, your pick attack generated envelope, or an LFO being your expression pedal (and your expression pedal could maybe control speed or depth)
if a sequencer’s too much, maybe just a sample and hold or step LFO

What’d be cool is that it could be used with any other EHX pedal that uses an expression pedal
