A configurable, virtual MIDI Piano Roll for your smartphone, tablet and PC making this the best thing to happen to Android for the sheet-musically challenged! My own clever workaround to Android's High Audio Latency truly makes this one-of-a-kind, you won't find another App like it. Keep in mind this is not a Piano Hero or Rock Band game.
SG57 Productions is the developer of the app which can be found in the Music & Audio category. The latest update of the tool was launched on Oct 10, 2014 and MidiRoll has been set up by over 100 users. People rated this application 3.5 on Google Play.
