[[ A STRANGE MUSIC TOOL FOR MANIAC MUSIC LOVERS! ]]
MIDIWriter is a unique app that converts keyboard input into MIDI note messages. Each character you type instantly produces sound. You can also enter a phrase and play it back as a sequence with adjustable tempo and loop options.
KEY FEATURES:
Built-in Sound Engine:
No external app required! MIDIWriter includes a built-in General MIDI sound engine with 128 instruments and 9 drum kits. Just type and hear the sound immediately.
Phrase Playback:
Enter any text and play it as a musical sequence. Adjust the tempo (1-480 BPM), enable loop mode, and let your words become music. Space characters can be used as rests.
Drum Mode:
Switch to drum mode to play percussion sounds. Choose from 9 GM drum kits including Standard, Room, Power, Electronic, 808/909, Jazz, Brush, and Orchestral.
MIDI Output:
Send MIDI to other apps or external devices. Configure MIDI channel (1-16), program change (0-127), and destination. Works with Virtual MIDI and MIDI Network Session. Can be used simultaneously with the built-in sound engine.
Keyboard Support:
Use the on-screen software keyboard, or connect a Bluetooth/USB hardware keyboard for a real typing experience. Supports Japanese input with proper IME handling.
MIDI Network Session:
Connect to Mac or other iOS devices over Wi-Fi to control CoreMIDI-compatible sound generators remotely.
Dark Mode & Rotation:
Full support for light and dark modes. Works in portrait and landscape orientations on both iPhone and iPad.
