My first post: EX800 Chorus Delay Time Mod

2017-06-02 by ashdot@...

Hello!

It's great to find this excellent community.

Thanks to you guys I've already transformed my 32 year old EX-800 into a synth that I finally like!

I installed the filter frequency and resonance pots and managed to control the chorus rate and feedback.

I would like to control the chorus delay time and this is where I would like your expert advice.

I see the built in LFO going into pin 7 of the MN3102 and I see from schematics of other chorus units that you can use pins 5 and 6 in tandem with pin 7 to create a variable delay.

How would you go about it?

Many thanks!
