Ph34R the M0dd4gE

A beast of a machine, this is what happens when controlvoltage unleashes full m0ddage power on a x0x!

List of mods:
Internal:
bass boost mod; carefully-selected transistors in key places (not a mod, but a good idea);adjustable amount of resonance boost on accent (trim pot on underside of mainboard). Also increased env. amount range, goes down to zero and up to 3x normal maximum amount.

I/O mods: CV outputs from the sequencer for Pitch and Gate (same as stock, now with 1/4" jacks), also Accent and Slide gate-CVs. CV Inputs for Gate, Accent, Slide, Pitch, and Filter Cutoff. New audio I/O is on a 1/4" stereo jack providing VCO out/VCF in, for a pre-filter effects loop or clean external audio into the filter/VCA. See my thread in x0xm0dz for more details. VCF input goes well with the "gate always-on" switch I added.

Panel/control mods:
Devilfish-esque VCO-to-Filter overdrive;
Accent duration control knob.
VCO->VCF FM, has FM amount knob and FM waveform selector switch;
Resonance Boost switch, with trimmer for setting boost amount
Gate always on switch - VCA wide open with infinite sustain. Good for bubbling liquid legato lines or external filter processing. Filter falls to minimum unless you are using my envelope mutator, or hit the:
Momentary Gate-Retrigger button; this fires off the main envelope generator when pressed, so you can inject some variety into always-on lines or just goose the sequence when you want.
momentary Accent-on button, similar principle as above, fire an Accent on demand.

Envelope Mutator - my own little street-style RC envelope circuit, takes in a +5V pulse and bleeds it to ground thru a variable resistance. This is then applied to filter cutoff, where it interacts with all the other filter mods to create delicious new flavors of groove. The source is selectable between Gate (all notes trigger the env mutator), Accent, and Slide triggers via a miniature 3pos. rotary switch; there is a mutation on/off switch, a Mutation Duration knob, variable between ~5 milliseconds and 5 seconds, and I am about to add a Mutation Amount knob for added subtlety. Right now it is either off or full-on.
