I have an H9 Max and an H90. I am using the Q-Wah algorithm. I am trying to get the very quick toe down – heel down “quack” effect (Jerry Garcia used it sometimes and my Boss AW-3 did t very well but is broken).
I tried using the envelope shape and the quick toe down portion is good but to get the filter to close, I have to play the note “staccato”.
I tried the ASDR, which is what I think should work but I can’t find a way to make the “S” sustain time very short and then “D” decay quickly.
Maybe there is another algorithm or setting that’s better suited to do this? After all these years I still don’t think I have fully discovered all the capabilities of these pedals!
