After you save the mp3 to your SDcard with Jukebox software, you can play it back on your 7000. You can then sync your playing the keyboard on the 7000 with the Audio file. Then save both the Audio and Technics file as a Technics file.
Now when you play back that Technics file it will play the combined performance. Of course both the original Audio and Technics file must be on the same card, and the Audio File must be in position 1 of any Audio folder for the sync to occur, and to load as one.
As far as singing along with a TechMidi file, the only way I know would be to record the TechMidi file to your computer, then with the appropiate recording software add your voice(s) Load the final performance to an SD Card via Jukebox, and then play it on your 7000 as an Audio file. After that, if you desire, you can sync the audio(play along on your 7000 with the Audio file) and save it as a Technics file.
If so futher desired you can record
that performance back to your computer, and add even more singing, etc. Then again save it back to your SDCard via Jukebox.
This is what I mean about the endless possiblities. I suppose you could do this forever and ever
By the way, you do not HAVE to play along on your 7000 to sync with an Audio file. Just let the Audio file play through, then save it as a Technics file. This way, you can put the Technics file anywhere you want on your SD Card..any folder..Favorites, etc. You can have Elvis singing in your Favorites list..cool
The important thing to remember is you have to keep the original Audio file in position 1 of any Audio Folder. So if you want, say, 10 Audio files saved as Technics files, you would need 10 folders, with each song at the top.
#1 in Folder 1
#1 in Folder 2
#1 in Folder 3
etc... Not sure why, but it works.
I hope I didn't confuse anyone. It's not that hard. If you have the writing kit, experiment, have fun, and maybe you can find other "cool" things.
