[sdiy] Boss PC-2 mods?

[Drew Smith]

	Hey folks,

	Been poring over the schematics for the Boss PC-2 "Percussion Synth" -
I'm loving the use of this thing as a basskick for techno, but as
before, it's not quite "snappy" enough.

	Basically, I'd like to increase the speed of the envelope - there's a
knob for "sweep" and another for "decay" - but I'd like to increase the
attack, or better yet, add a knob for it.

	I'm kinda lost tho.  CyborgZero (Rob) filled me in that you need to
spike the oscillator with a higher voltage in order to get more of a
sharper attack, and I've accomplished that by just using a higher value
of powersupply - tho I figure this isn't the best idea, and I'd rather
approach it on a better level.  Would it be as simple as replacing R26
and R27 with variable resistors?  Or perhaps the "sweep" pot with a
different value, greater than the 1k?

	I'm still new to this. :)  Any suggestions are welcome, I'm trying to
make this into a more TR-909-sounding basskick...

	Cheers,	
	- Drew.
