	Well, it looks like my Polysynth keyboard scanner and voice
	assignement. It was done all discrete logic (no FPGA I mean).
	This kind of assignment seemed to be the only reasonable mode.
	And I didn't know about other circuits then. That makes me,
	hmm, a genius ;-))

	It is no problem, really. Actually now I can't see other way than
	uC/software for this kind of job.
