Hrm, weird. Let me send you my Syphon Plugin. Theres a chance I might be using an unreleased version? Maybe? Hrm.
As for patch time, just replace it with an integrator, and use your ‘speed’ as the ‘value’ for the increase / decrease of speed. No need to put it in the iterator.
Did you remove other patches like Kineme patches, etc in debugging this?
