Hello everybody,

So I have this Korg LP-350 piano which has MIDI I/O. I want to send MIDI info to my audio interface, and from there to my computer.

I have the MIDI Cable in the the LP-350's MIDI Output, and of course the other end in my audio interface MIDI Input. However, I can't get the LP-350 to send any information. My audio interface (Presonus AudioBox USB 96) works perfectly fine, so I guess there's something that I'm missing with the LP-350.

Has anybody gone through the same problem or knows how to make it work? Anything will be helpful!

Thanks!!

(By the way, I have already checked my DAW's MIDI connections, tried every connection possible but nothing happens)

The MIDI Out port on the LP-350 needs to be connected to the Presonus MIDI In port.

The MIDI data being sent from the LP-350 consists on Note On, Note Off, Velocity, and other messages. It doesn't contain audio data.

If you want to receive the LP-350's audio signals to the computer via the PreSonus, connect the LP-350's Line Out jack to the PreSonus' Mic/Inst inputs 1 and 2, using a suitable cable. Set the PreSonus inputs 1 and 2 to L & R.

Hi,

When you say that your audio interface works fine, do you mean that the MIDI IN works fine with another instrument?
What about the other direction? Send from your DAW notes to the piano (MIDI OUT on Presonus to MIDI IN on piano)?
You can try also to use the software MIDI-OX as a monitor of MIDI IN events on the Presonus. This to rule out incorrect settings in the DAW.

Good luck.

Which DAW are you using? There should be a MIDI setup menu somewhere. There is no need for Korg MIDI drivers, since it is the PreSonus that is the USB MIDI device. The MIDI data coming across the DIN connected ports is relatively agnostic.

Hi,

To rule out your piano itself and MIDI cable you can try the following:

* Disconnect all MIDI cables from the piano
* Check it plays ok
* Set up the piano in Local Off mode. I.e. the piano will still transmit MIDI notes to the MIDI DIN OUT port but no longer internally to the sound engine -> hence no sound anymore
* Check that the piano indeed makes no sound. So the keyboard is internally disconnected from the sound engine.
* Now make a MIDI loopback: run your MIDI cable straight from MIDI OUT to MIDI IN on the LP-350. No other devices needed in between.
* Check that your piano makes again sound

If the last step is ok, this proves that your Piano transmits and receives MIDI notes properly and that your cable is ok. Then the problem must be elsewhere (audio interface, driver for the audio interface, settings in DAW)

At the end, don't forget to open up the loopback and switch to Local On mode.

From the manual:
To switch between the Local On/Off settings, hold down the TRANSPOSE/FUNCTION button and press the [PIANO 1/L] sound select button. Each time you press it, the Local setting will alternate between On and Off.

Good luck
