Works great, like synthesia I use it to play midis so I can double check that I'm reading sheet music right, works great. You can slow it down, pause, rewind, and shows all octaves/keys, unlike other apps I tried.
As good as it gets If it could play slower than 30%, it would be very useful.
Fantastic Learning Tool. Best of its kind on the Play Store. An awesome app for anyone who wants to learn any song on piano - Just find a MIDI file, load it in MidiRoll, select the song and begin learning it in no time. This is a close as it gets to Synthesia. Stable with smooth playback and navigation. Developer is quick to answer questions and fix bugs. This immediately found a spot on my home screen. Looking forward to future updates!
Great Had to re write my review, crashes are fixed and the update made it work. I finally got to use it and its working well! Dev replied quickly and now I'm happy with my purchase.
yes you ARE superman no wait, you are GOD for creating this extremely fun and useful app, and its only $2 wow your the best dude
Just crashes just crashes every single time I open any type of a midi file.
