I Was Running Midisoft Studio 4 and playing Midisoft MK-4902 Keyboard with no problem. Next day keyboard wouldn't work because the MIDI input file (MPU-401) was not installed. Anyone know why this file disappeared? Anyone know how to install a new one?
I have tried to use system recovery several times,to go back to,when the MPU-401 was still installed, but for some reason the recovery would not complete. I also tried to copy a MPU-401 file from another computer to the Windows system32/Drivers folder but this didn't work either. I have seveveral other Audio Production programs that need this file for making inputs.
Please give me any help on this that you can.
