4 Tracks is VERY SIMPLE to use !! it mimicks a little metal device, the ergonomics of 4 tracks will be hard to beat !
It allows you to record in multiple takes. I developped it to practice the guitar but it could be used for anything.
4 tracks plays back prerecorded tracks while you record a new one.
To use 4 Tracks, although you can use the iphone microphone, it is best to plug in your headphones with microphone and play or sing up to 4 tracks.
Now you can still play your favorite instrument away from home, 4 Tracks comes with an internal synthesizer and you can play with a keyboard or a guitar type controller.
