major bug detected!

Hello. I am here to inform you about a major bug I have encountered that needs to be addressed and fixed as soon as possible! I played the midi file on the devices own midi playback and pushed "stop", only for the midi tape to start playing from the beginning again. It is impossible to stop the midi unless you close the app, and, well, it really gets annoying. Please fix this bug and I will give your app 5 stars.
