Brought the midjay home. I will test it extensively this upcoming weekend. As it plays mp3 and wave files plus midifiles, means I can use many many backingtracks available for guitarist, not worrying about PC trouble. Plus I can synch .TXT files with any file type, which means I can finally throw away my text book.......maybe not quite.
The SFX are wave files are of course very real. The only gripe I have is being used to the Yamaha OS, the Ketron way of thinking is something I again must relearn. I owned an MS100, so it shouldn't be too hard....
The 10 playlists with up to 10 .mid or mp3 or .wav are a great feature that I can see being used right away.
I'll let you know more later.
