Trouble shooting tips:
For running DRFX.exe program, a sound card providing MPU401 compatibility must be installed in the PC,
typically the game port.
Midi out of this MPU401 board must be connected to MIDI IN of the SDP-20.
(MPU401 board is doing the conversion from parallel PC data into MIDI OUT
serial data).
Check also in the Control Panel, Multimedia, Midi, that midi device selected is your MPU401 board midi device.
The midi device selected in this setting is the midi device used by DRFX program.
