MIDI is a standard about controlling audio devices.
You can control musical instruments with separately sold MIDI adapter for iPhone/iPad.

The internal FM synthesizer processes only note on, note off, and sustain control, and ignores the others.

This app may sound even if the device is silent.

The internal synth receives signals of the selected receive channel.
The synth will not sound if the channel is different.

Do not hesitate to write a review if you encounter some troubles.
