OPNMIDI Player

A simple OPN2 and OPNA Synth based MIDI Player with use of libOPNMIDI

It's a small and simple MIDI player with OPN2 (Yamaha YM2612) or OPNA (YM2608) FM synthesis. The player can play any MIDI, MUS, or XMI file you will have on your device. Player has General-MIDI and Semi-XG compatible bank timbre bank made from imported instruments from various Sega Megadrive/Genesis games, ported from OPL3, or originally made. Optionally you can use external timbre bank file in WOPN to get the different sounding of your music.

# Key features of the libOPNMIDI synthesizer:

* Pan (binary panning, i.e. left/right side on/off)
