bismark m16 is a MIDI player app that loads SMF (Standard MIDI File) for the GM (General MIDI) specification as Song files. Song files are managed in the "m16" folder of your iCloud Drive and kept in sync across all your iOS / iPadOS devices. You can also bring MIDI files in directly from other apps using "Open in m16" or the Files app. 16 icons across the top of the main screen represent the 16 MIDI channels. Tap once or twice on an icon to mute or solo that channel. Long-press an icon to open the Part editor, where you can adjust volume, pan, reverb send, chorus send and delay send, and choose the instrument for each part. During playback, the icons show live performance information in piano roll, circle or MIDI analyzer view. Along the bottom of the screen are transport buttons and a slider for play/stop, seeking the song position, and changing key and tempo. Now Playing information — including elapsed time and playback state — is also shown on the Lock Screen and in Control Center. m16 supports background MIDI playback, so you can play along on your favorite instrument app while m16 plays the backing track behind it. m16's built-in synthesizer plays through the GeneralUser GS SoundFont. If you'd rather use your own gear, m16 can send its output over CoreMIDI, or Bluetooth MIDI to external modules and other Virtual MIDI compatible apps — and can even hand off playback entirely to bismark's companion synthesizer app, bs-16i, for a wider range of instrument sounds.
