Korg d3200. I can't play or burn cds all of a sudden. Says no disc after inserting a disc. What up?

If you contact Korg, they can send you a dowloadable link to burn the software to a disc.

I will assume you want to sync the two as one. I have one of these sitting in a closet. The 3200 will record 12 tracks at a time if I remember correctly. I believe the Korg will sync to Midi Time code. I just wonder if the midi implementation allows for start and stop code. Anyway, I found this information:
x2. MIDI messages used by the D3200 Note On (Note, velocity), aftertouch, pitch-bend:
The D3200 uses these messages to control effects.
Program change:
The D3200 uses these messages to switch scenes.
Control change:
The D3200 uses these messages to control mixer and
effect parameters.
MMC (MIDI Machine Control):
MMC messages can be transmitted from the D3200 to control an external MMC-compatible sequencer or recorder. MMC messages received from an external sequencer or recorder can be used to control the D3200.
MTC (MIDI Time Code):
The D3200 can transmit or receive MTC messages to
synchronize with an external sequencer or recorder.
MIDI Clock:
The D3200 can transmit MIDI Clock. It can also receive MIDI Clock if you have selected MIDI Clock for the tempo track and are recording the tempo track.

6. Playback
(1) Set channel 1 to play.Turn the REC/PLAY key on. Then press the channel key of track 1 (the track you just recorded) to set it to Play (key lit green).
(2) Return to the beginning of the song.Hold down the STOP key and press the REW key to return to the beginning of the song (?p.37 "2. Location").

If you have electronic expeerience, take it to a repair shop. You can cause more damage okiong around if you don't know what you're doing.
Past that, contact Korg customer service for the schematic and parts list. The part should be available from Korg directly of from Mouser

The import needs to happen from a computer (or a CD-RW) >D3200, not from a flash drive or backup drive.

yes- check out the m-auduo studiophile speakers & there are other brands that are better depending on your wallet.

If the buttons are just sticking at their sides in the panel, lube with a tiny bit of CRC 226 on a Q tip. Get the CRC226 at Home Depot in the electrical dept. If the button mechanisms have failed or plastic hinges have broken then replacement is only option. Losing 4 of these to same problem is RIDICULOUS... time to change brands.

See if you can download the original "demo song" into the unit and see if the demo works. Should be able to find that on the Korg site under support.

Unless you are electronically adept and have certain tools I would NOT attempt this yourself. You could damage the circuit board causing great repair expense.

Korg is a great company and when you contact them they will help you. They can tell you how to get the CD and/or how to download and burn it to your own CD. then you can boot up the device
