The purpose of the test - the validation of DP's play a waltz by Chopin.
Found that in my test suite (http://yuri-pavl.com/piano-test) lacks Kawai.
(now in the collection of 12 tools and 19 voices).

Help to test - pass through Kawai my MIDI file and get the MP3, it is desirable to disable reverb.
This MP3 please send me (yuri.pavl @ gmail.com) or give the download link!
If you have another tool, which is not yet on my list, too, will be very much appreciated!

Thank you!

I'd like to send you a mp3 rendered with my Kawai CA 63, but unfortunately it is not possible for the CA93/CA63 to convert a MIDI file stored on USB memory to an MP3/WAV file. The 'Convert to Audio' function only works with recorder songs stored in internal memory.

supertorpe, is it possible to connect to a computer via USB and transfer MP3 recorded in the internal memory to the computer?

The problem is the location of the MIDI file, it's not the location of the MP3 file.

The piano only save an mp3 from a song stored in internal memory (those songs I play and record directly at the piano), thus it can't save an mp3 from a song stored in an usb drive.

I add Kawai MP10 into test (thank you Michael!) and another bank SV1 and Pianoteq 4 Blutner.

About recording - Michael gave links to instruction pages:
======
Page 44: The CA93/CA63 digital piano also supports the playback of standard MIDI File (SMF) song files stored on a USB memory device...
Page 45: The CA93/CA63 digital piano allows recorder songs stored in internal memory to be played back and saved (converted) as an audio file to a USB device in either MP3 or WAV format.
Page 76: The USB menu contains functions to load and save recorder songs from/to a USB memory device.
Page 77: The Load Song function allows recorder songs stored on a USB memory device to be loaded into the instrument's internal memory.

Hi ,

is iit not possible to play the midi file to your Kawai by using a computer (sequencer) and record the playback to the USB stick ? Worked for me on the mp6 and es7. I assume the CA is not much different in that respect ?

So import the midi file in the computer , make sure there's a working midi connecties between computer and Kawai, put the Kawai into record to USB mode, start recording and play back the midi file from the computer. Stop when the midi file is done. Save and send the mp3 or wav recording.
