Modded TR-909

via greg on the AH list:
"i did the colin fraser mods (all fantastic), plus:
extended ranges for most of the decay and pitch controls
snare pitch envelope alteration switch (removes pitch decay or increases depth)
snare noise filter frequency
snare vco2 pitch
tom pitch eg cut
tom vco2 pitch
tom noise level
rim shot pitch
clap pitch
clap number (of "claps")
clap speed
clap reverb level
hh swap switch (swaps open and closed samples)
crash and ride extended pitch switches
trigger mute switches for all sounds
noise shift register tune (adjusts the rate of the noise down to digital crunchiness)

most of these were pretty easy with the schematics, swapping resistors, etc.

i think all these mods are quite useful.
