[sdiy] TR-505 Help/info wanted

[bart]

Hi there all,

I am new to this list again (was subscribed but my hotmail account couldn't keep up with the messages you all wrote)

Can any body help me: I AM TRYING TO MOD MY TR-505 (i know it ain't analog, but still).
If anybody knows anything about this piece of shit ;-] 

Any help would be appreciated.

I was thinking about:

IC pinouts, schematics, service manual, idea's block schem's or anything else.

I heard it was possible to route external audio thru the envelope. (is this true?)
I heard it was possible to maybe put a decay pot on some sounds. (cymbals i reckon)

I know it is possible to put on some extra sequencer buttons (connect pins to ground) to alter the playing of your programmed beats, delete all sound in real-time, some more i will write down when i have some more time.

Any help will be appreciated,
Bart
