Ok, awake again. :)

PLEASE EXCUSE THE WIDE PICS! (they make great desktop backgrounds, heheheheh)

Here's my Simmons SDS-800 drum brain, plus modifications:

Mods are: installed PAIA MIDI2CV8 MIDI-to-CV controller board, set to be eight trigger outputs. Since the SDS-800 only has four voices to trigger, I made the other four triggers go to 1/4" trigger-out jacks. :) Also removed the power switch (who uses those?), removed the attached power cord (UGH, HATE THOSE) and replaced with a "Euro" style connector... which just happened to fit almost exactly into the hole where the power switch was. Also removed the headphones jack and replaced with a MIDI activity light.

Also *sort* of visible at the top middle is an extra knob (the one with a small, blurry brass screw in the side) - this is attached to the second decay envelope I built onto a 1" x 1" circuitboard and installed. I was in there the other day, cleaning some dust out of the pots, and *man*, was my soldering work poor back then! :)

My SH-101, plus modification:

Mods installed - a Synhouse MIDIJACK - oh, and a MAZDA emblem I found on the side of the road in Costa Rica. My girlfriend hates it that I pick up shiny things off the side of the road. :)

Oh, and one more, a much older one:

From about four years ago; the SDS-800 again, with no modifications yet, being triggered by the indy-outs of a TR-707 - downside, the kick envelope doesn't start to decay until the trigger signal goes back to zero. The kick sound on the TR-707 is short, but still a few hundred milliseconds long - the trigger mods done later brought that down to 5ms, which results in a MUCH snappier kick!

The device on the right is the cool part - it's a dual lowpass filter built in a Canadian military ammunition case. With the top on securely, it's waterproof to something like 100 meters. :) The front panel was cut out of the side of an old computer case with my Dremel tool, then painted black, then labelled with a silver pen, then sprayed with clear plastic sealant. It looks very homemade. :)

Also in that pic, near the top, you can see a poor view of my first mod ever, a Boss PC-2 Percussion Synth - I tried to add a few mods, some successfully, some not so. :) Easiest mods - switching the oscillator from square to sine to none, switching the "beater strike" on and off, and an early (failed) attempt at adding an extra decay envelope.
