ahhh great! Pam's and Steppy work wonderfully. And yeah, at minimum you want one envelope per sound you're making. Another pair of ADSRs and/or Scenes will let you be a lot more flexible. One other fun trick for hats is to set the waveform of one channel on Pam's to be a short decay envelope and have it at x2 or x4 tempo. That frees one of your actual envelopes for other duties. Plus you can do some euclidean things or random skips. Good times!
