Here are a few I have heard about:
Poor Man's Duophony
KB CV OUT ---> S&H IN
KB TRIG OUT ---> S&H CLOCK IN
S&H OUT ---> VCO2 ONLY EXT CV IN
Tune both VCO to unison, make sure both are turned up in the mixer, set EG2 Release to 0, avoid excessive Pitch modulation to better hear the effect. Playing some notes gives this result:
- On each staccato keystroke, VCO2 will give the pitch of VCO1 from the previous keystroke. So you have to hit a key twice in order to make both VCOs the same pitch. Nice for canon-like melodies.

And Neandrewthal PMed me the following regarding MS-20 + Moogerfooger pedals:When I first got my MS20, I noticed that the filters don't track the
keyboard at all. I plugged the keyboard CV to the filter CV in, but
then the filter tracked the keyboard slowly in the lower octave, then
went screeching off in search of tweeters to kill! I soon realised
that the filter was tracking exponentially. I looked at the schematics
and sure enough, both the VCOs and the VCFs have exponential converters
on the modulation inputs. So, if you stick a V/Octave input into the
modulation inputs and adjust the MG level for correct scaling, it all
works and the filters track too.
Here's how you do it.
1. Plug the performance wheel into the keyboard CV input (middle, right)
to disconnect the keyboard.
2. Plug the V/octave CV from your MIDI/CV converter or another synth
into
the Total jack (top left).
3. Plug S-trigger from your MIDI/CV or synth into the MS20 trigger
input.
4. Play a note on your MIDI keyboard or the controlling synth, and
adjust
the MS20 performance wheel until you get a sensible pitch.
5. Adjust the VCO mod levels until playing an octave on your MIDI or
other
synth keyboard gives an octave out of the MS20. Then adjust the MS20
performance wheel to coarse tune the MS20 and use the tuning pot to
fine tune it.
6. The filter mod level pots adjust filter tracking in the same way.
7. Enjoy.
There are some more (with sound samples!) at http://www.korganalogue.net/korgms/mstt.html.A few of my favourite patches with the foogers:
Env.1 (triggered by keyboard) out to the cutoff on the mooger filter. If that signal is split and put to the MS-20's HPF it makes a good double resonant bandpass.
LFO out to the mix of the mooger filter(which is completely closed) for instant tremelo.
Osc from the mooger ring mod to VCO1/VCO1 CV in for FM.
Triangle LFO from ring mod into sample and hold(clocked by MS-20's square LFO) to LPF for stepped filter sweeps and to VCO CV for
quasi-sequencer action.
