Pertaining to these mods...

I'm interested in implementing some of your mods, but I'm not seeing these reflected on the schem.

you say...

"Changes include:
# Removed depth control. (I used another depth control method)
# Removed drive control.
# Converted speed control to run off of an optocoupler. (You can use the LERA now)
# Converted LED driver to run LEDs off of V+ instead of ground. (Gave a nicer swing for my tastes)
# Various component changes to give a wider speed range."

Which depth control method did you use??
The rate control on the schem; I don't see any optocoupler there??

You would replace the 100K pot with the optocoupler. Most optocouplers only have two poles, the original Easyvibe circuit needed all three poles of the pot. The modded circuit I give there gets the speed control down to two poles so it could be replaced by an optocoupler. At the time people were asking how to adapt the LERA to work with the Easyvibe.

As for the depth control I forget what I did at that time. I used a different audio section from the Easyvibe so I think I changed the phase signal mix or something like that.
