Not a 4 track, an infinite "sound-on-sound" recorder.
Its fine, its free, its fun. You dont get 4 discreet tracks. The 2nd track is a combo of 1 AND 2. The 3rd can be recorded with trk 1 only and/or combo track 2 or both using dB slider. You can improve quality by turning DOWN initial tracks. Over-compression is the cause of the noisy quality. Theres a 4 count wait before you can record. It WILL let you get your ideas down, the whole point!
