i had a 4 track cassette based recorder and used it in conjunction with a boss dr. rythem section....i got great results. the dr rythem section has 4 digital tracks on its own. you have a drum track, and 3 tracks to do bass, guitar, keyboards...or what ever. it is real simple to use and seems to have alot more variety of built in drum patterns that most other similar devises i see. I wouldn't hesitate one second to recomend it for creating songs...and getting pretty damn good results on tape when your thru.
the buttons are layed out like a guitar neck (6 rows of buttons) so... if you can play guitar you can program key, strings, horns, ect...
also, you can push a button and switch it to the "chord" mode and the first 3 rows of buttons are the root note of the chord and the 2nd 3 rows of buttons are the type (major, minor, diminished, sustained, 5ths..6ths..7ths..in major and minor ect.....) every damn chord type you can think of. when you do a chord in this mode ...one little window with a key board shows you how to do it on a keyboard and a guitar chord chart shows it on a guitar neck.
so...you can do 4 tracks on the boss unit and put that on one track of you 4 track and you'll have 3 tracks left to do guitars and vocals...mix it down to stereo and go to your computer and burn a cd.
I have learned alot about chords and keyboards with this thing.
peace
