Vortex Sound Research

Hey probably really obvious but I want to be able to modulate the clock from Pam's to change speed from like 30bpm, then to like 85bpm then too 140bpm.

Is there a way of doing this with a envelope generator such as ZADAR?

Here's what iv got currently, just made a patch when slowed down it sounds like a while different loop.
