Otherwise Pam's should have ratcheting and bouncing ball envelopes, no? You can also (self)patch lfos or envelopes to its CV inputs and have that control clock rates or divisions of certain channels.

Aha -- you're right! I didn't realise that I could modulate the clock division, that is indeed the right move. Will need to play with that next time. I don't think that my version of Pam's (PNW) has ratcheting, but CV to clock will open a lot of possibilities in that direction.
