Interesting post, and like many others have found, the recording instructions in the manual are pretty hopeless.
I have the PSR-SX700 and so I thought I'd do a short, simple guide as to how I do it, which may help. I can't see that the SX900 would be different, but as I don't own one, I can't say that definitely.
So here's the easy guide that answers a few of the queries.
Firstly. Set up the song that you want to play. So get the keyboard ready to play with the music, style, registration or whatever.So hopefully, you're now all ready to record.
1. In the SONG section, press the RECORDING button
2. Now press the AUDIO Quick Recording button.
3. Press the Flashing red REC button which will turn it OFF.
4.Now, in the top right press the 3 Horizontal Bar button which will open the format window.
5. Press the AUDIO REC FORMAT tab and then select from either WAV or MP3 format.
There are 3 settings for MP3 choose the one you want. I use the 128kbps setting but you can experiment to see the setting that suits you the best.
6. CLOSE the Audio REC FORMAT window with the X in the top corner.
Now you're set up to record in the format you want.
7. Press the REC button again, and it will start to flash.
8. Get your head together, because this is it.....and press the PLAY/PAUSE button, and start to play. Your recording now begins.
You will notice, on the screen, that the recording will be described as AUDIO 000-1 It may be different (see later)*
9. When you have finished your recording, press the STOP button.
The next step is important...
Press PLAY to listen to your recording. If you are happy with it, then you don't need to do anything further. it will automatically have been saved onto your USB stick as AUDIO-0001
BUT.....If you need to re-record it then you MUST press the REC button again.
*When you do that, the counter will move from AUDIO-0001 to AUDIO-0002
If you don't press the REC button, when you come to re-record, then the old track will start to play just as you start your new recording and it will sound awful. So to RE RECORD press the REC button, which moves the counter to the next recording track.
When you are absolutely happy with your work, then you can finish recording. You may by now have had several attempts at recording, and so you could well have files called Audio 0001/2/3/4/5/6/7/8 etc files. I did one the other day and had 14 attempts at it before being entirely happy.
So now....Go to your computer with your memory stick, and open it up.
You will see all these new files listed. Choose the one that is your final version, (make sure you've made a note of it), and transfer it to your pc. Rename it....So in my case AUDIO-0014 was renamed to "Sexy Eyes" . Then keep a copy on your PC and only keep this one file on your memory stick. It is now a named file and you can store it where you want on your instrument files.
Finally....Delete ALL the older (bad recording) attempts from your memory stick. That way, when you go to record your next song, you'll start the counter again with AUDIO-0001.
I hope this helps some of you. I had nightmares getting it working, but I can now do it pretty easily doing it this way. You will be able to do so too. Any issues...Ask.
There are probably many other ways of doing the same job, but this is simple, and it works. I'm not a professional musician, and working out some of the features on this super keyboard has taken many hours of head scratching, and experimenting.
