When I try to transmit any data from computer or to recive from KP3, I get error message that conection is paused

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.

Take it appart rub it with pure alcohol an put the touchpad together again

Try www.rswww.com (RS/ Radio Spares). They are normally really good.

You would need to use a TRANSFORMER type stepdown. If you have used one of the cheap ones intended for hair drier type appliances you have damaged your unit. You will have to send it to a repoair facility in that case. Here is example of CORRECT type:

This may be or not be a solution, but most times you have to format the SDHC card so that it is recognized by your Korg

Usually in any type of situation when data is being transferred and the connection is prematurely lost there is data lost and or file corruption.

My suggestion:

Connect the Boss Rc 50 to your computer and backup its entire contents to your computer if possible.

Next perform a Hard Reset: While simultaneously holding down the "PLAY MODE" and "LOOP SYNC" buttons, turn the power on. Everything should be restored to factory settings.

If your backup was successful, then you can transfer desired files (one at time) to determine if the are usable. If a file causes errors or malfunction, then most likely it is corrupt.

Hope this helps

You need a powered USB hub -if your hub is powered you need a better powered hub (some of the cheaper units don't transmit data without fluctuating)

I agree, it's probably either the power supply (has it a fuse?) or the power connector or the power switch or an internal fuse. Probably a simple fix.

You likely have lost the internal memory data. This can be due to a power surge or that the internal battery has been depleted. The battery may need to be replaced.

You should reset the unit and reload the data, The manual is available online. Search Google for it.

The manual STRESSES the importance of backing up the data.

If you don'thave the backup, you MAY need to find another SR-16 owner to clone the data from.

simple bro. . .. flick the korg kaoss pads setting to send . . u will find this on the back. . . i thin you have it set to direct. . flick it over to send and then let em know if it works. . . and could u answer ASAP what cords you used to connect the kp3 to the send return on your mixer. . .thanx
