I received PCB and soldered components.
This SD MIDI][+ card would have below functions.
MIDI IN/OUT: Passport MIDI card compatible.
MIDI Sound Module support
MIDI IN-> Play (Sound module required): will work as a MIDI sound module.
AUX Output Pins for special device.
I need to make firmware for it.
After some fixing bugs, I will order final board and then we could have good MIDI card for APPLE II.
