Jamzone professional backing track alternatives
I just downloaded Jamzone which is a great backing track type app, with independent tracks (including voice), which shows the lyrics and chords in real time. Very good audio quality, etc ... but it does not have configurable cc #, each song costs $ 2.99 to $ 1.60 (package c / 50) and all english. (I need Brazilian music too)
Any professional alternative (multi-track) with lyrics support + midi + sf2 besides cc #?
The idea is to pay for the app and not the songs.
