CS-50 !!

	weird blinking lights has a cs-60 in our analog aresenal,
	as well as a cs-10.  both fine, fine, amazing synths.

	btw, got the sbk-80 syncing both the old roland gear as well 
	as the r8mkII and the other midi stuff tonight.  just took 
	a little hacking, as well as some manual reading.  it's like,
	in the end, to have the r8 be the master and the rest be the
	slaves, but we'll see if that is possible.  does not look all
	that promising from this angle, however.
