TuneCanvas

Free App that lets you drag notes on to a musical staff to create songs. There are 4 instrument tracks and 1 percussion track. A keyboard is included for play along

Tune Canvas gives you a palette of musical notes and rests that you can drag on to a staff. You can play 4 instruments and one percussion track simultaneously. Each instrument track is color coded. You can control the volume, instrument and transpose each track separately. Tune Canvas can export your musical creation to a midi file. The only time an Ad is played is when you save/load a file.
