[sdiy] Boss PC-2, JoMoX XBase-09

[Drew Smith]

	Hey again, folks,

	Just getting into DIY - just finished my first project ("Electronics
Projects for Musicians"; dual filter), and I'm waiting on the delivery
of my new BassAce synth board and PIC.

	I know what I want my next project to be - a killer basskick.  I do
live-pa techno, and that's really the cornerstone that I need...
currently using a sample of a TR-909 kick on a Sequential Circuits
Prophet 2002+ sampler, heavily filtered with high resonance... it's
really nice, deeeeep and thick.

	However, I heard a live-PA the other week who used an XBase-09, and
that basskick blew me away!  So, I want one - but I don't wanna pay
$1200 CAD for a basskick!  Also, using that sampler as my kick is a
pain, and I'd rather be using it for vocal samples and leaving the kick
to a dedicated unit.

	So I've got the Boss PC-2 to start from - did some quick chatting with
the live-pa guy with the XBase, and discovered some more about it -
controls are similar, there's a pitch, sweep (only downward sweep
tho...) and decay, as expected, but there's also a knob for "Pulse"
(width?), a knob for noise (wondering what it's using as a source), and
one for "Harmonics".  There's also an EQ knob (passive filter?) and
another knob for "attack".

	So, all told, sounds like there'd need to be some serious modding of
the PC-2 before it became an XBase - a ringmodulator, a passive filter,
an envelope generator, pwm... sheesh.  My skills stop at "I wonder what
it'd sound like if I used a pot with double the value!". :)

	Anyone built an "ultimate basskick" circuit?  Is there one available on
the web somewhere?  Any recommendations or tips, or pointers to
documentation that's relevant? Remember, I'm a newbie to this, only
getting started, but I'm eager to learn. :)

	Cheers,
	- Drew.
