Re: Nice mods.

Since I repaired the oscillating part of the MG/LFO I gave the KLM-367 a little mod for increasing the LFO speed. I wanted to increase it by an order of magnitude, so according to the series capacitor equation, I can do that by putting a new cap of say 0.033uF in series.

I actually soldered a 103K one (cap code) to get around 0.01 uF.

Results: as expected, my LFO now goes to audio rate or so. I get all types of sounds like vowels or formants to noise at extreme values of Frequency and Level. Very cool.

Side-effects: when my MG Frequency is a 0 and Level is >0, the MG is still there.

Now, what I would like to do is connect the Envelope to the MG Level. The question is: how?
