This library implements three things:
	- a set of structures which constitute the codes and registers of
	    the Yamaha dx7 synthesizer,
		dx7.h
		dx7_globs.c
	- a virtual dx7 using these structures,
		da_dx7_voice.c
		da_vdx7.c
		dx7_out_err.c
		send_dx7_bd.c
		send_dx7_pc.c
		vdx7.c
	- a set of midi command disassembler routines for the dx7.
		da_dx7_sx.c
		sx_dx7_1v.c
		sx_dx7_32v.c
		dx7_ctl_name.c

Routines from the third item are incorporated into the program mpuda(1carl).
See source directory of mpuda for how to incorporate other synthesizers
into the disassembler.
