Hey, thanks for everyone's help. I took the hlx file created by eschworld and made the following changes:
1) Changed the Simple Pitch blocks to Pitch Wham blocks
2) Assigned each Pitch Wham to a switch (Footswitch 3 and Footswitch 4)
3) Set one to have Heel Pitch of 0 and Toe Pitch -12
4) Set the other to have Heel Pitch of 0 and Toe Pitch of +24
I think it would have been easier to understand what I was going for if I'd added that it's for the Black Keys song Lonely Boy. He uses a pitch wham dropping an octave in the beginning of the song and at one point in the middle. At the end he uses a pitch wham going up 2 octaves.
Thanks
