Best for trance music. I've also added 10 jack sockets, so there is many more things you can do : Proper CV Gate Input / VCF Cut Off CV / PW /VCA (volume limit control) / MOD / Portamento CV Switch Input / Accent CV Switch Input / Selector for accent (VCF/VCA) / Ext Aud input for VCF / Ext Aud input for VCA. Well, there is plenty more I can add to the MC-202, but there is really not much space in the MC-202 box, I've almost use every single inch of space in there. I could of use a wooden case just like my TR-606 mod, but I couldn't be bother to spend so much time just to make a wooden box.
Mods on the MC-202:
1./ LFO switch : You can choose from Super Slow Sweep / Normal / Crazy Fast
2./ Proper CV gate Input : The MC-202 does have CV/Gate In's and out's. However, it's a known problem that the CV/Gate Inputs have slight problems, since many data are actually quantised before they reach the Synth section. This is because the CV/Gate In's are routed and pass through the internal sequencer CPU then out back to the synth.
3.) VCF Cutoff cv (input) : When a jack is plugged in, the CV is ADDED to the VCF Cutoff Frequency slider setting.
4./ PW CV : When a jack is plugged in, the CV is ADDED to the PWM Slider setting
5./ VCA (limited Volume Control) : The VCA CV In doesn't produce any dramatic effects, it acts like an extra Volume Control.
6./ MOD : Actual MOD on the MC-202 goes from the LFO Sine output to the MOD Slider. So it is possible to tap a CV IN to the mod...
7./ PORTAMENTO CV SWITCH INPUT ( +5V will turn Portamento OFF. 0V will turn it ON. ) : Note: +5V will turn Portamento OFF. 0V will turn it ON.
8./ ACCENT (VCA) CV SWITCH INPUT ( +5V will turn ACCENT ON. 0V will turn it OFF. ): +5V will turn ACCENT ON. 0V will turn it OFF.
9./ ACCENT (VCF) CV SWITCH INPUT: +5V will turn ACCENT ON. 0V will turn it OFF
10./ Selector for Accent -> VCF/VCA (toggle switch): MIDI AUX GATE Out to switch between going to the VCA ACCENT and the VCF ACCENT. When switched, AUX GATE is going to BOTH Accent VCA and Accent VCF, and this actually activates the Accent VCF.
11./ Ext Audio Input to VCF Source Mixer: all the VCO's and Sub-Osc are mixed at the VCF Source Mixer
12./ Ext Audio Input to VCA"
