tremolo speed control

[calpolyengineer]

Hey all, I am thinking of building Craig Anderton's tremolo, but I want to add another input jack which would bypass the speed pot so that I can use a Toadworks Enveloope to control the speed of the tremolo. I don't know how to do this, or if anything else needs to be done to the tremolo to accomodate this option (besides the new jack). Any help would be GREATLY appreciated.

Also, here is the link to the tremolo schematic.

Find a way to disconnect the LFO output voltage from the LED part of that LED/LDR combo, then apply the DC voltage from your envelope follower to the LED.

You could use a part of the tremolous lune instead.
