Hey Mike, classic vintage gear woes! If your X3 floppy drive is dead, try using a USB floppy drive on your PC to copy the .SNG files. Once you have them on your computer, you’ll need a special tool to convert Korg’s .SNG to standard MIDI. There’s no official universal converter, but searching for Korg X3 editor software or community tools like sng-to-midi converters might help. You can also try importing SysEx data into Cubase if you can extract it. If nothing works, recording the MIDI output live from your X3 (if it powers up) is the last resort. Retro gear can be tricky, but the tunes are worth it!
