Midi Stroke

Midi Stroke is a free music trainer for piano, drums and saxophone. Connect your MIDI instrument: a keyboard, an electronic drum kit or pads, a wind controller by USB or Bluetooth, and play along with a score that scrolls under a cursor. • Rhythm mode scores your timing note by note; Practice mode waits for the right notes. • A count-in, a visual metronome riding the cursor, and results at the end of every piece: your precision, your timing, where the mistakes were, and your progress session by session. • A library of studies, folk tunes and exercises; a scale and arpeggio generator; the 653 most common jazz licks of the great improvisers; 1,150 real drummers' grooves; theory lessons; and rhythm games that need no instrument. • Bring your own scores (MEI): repeats, D.C. and D.S. are written out so the page reads straight through. Midi Stroke is made in the open by Vibetuned, a non-profit for music and arts education. It is free software (GNU AGPL v3): the source is at github.com/vibetuned/midi-stroke. Music notation is engraved by Verovio (verovio.org), © RISM Digital Center, used under the GNU LGPL v3. Grooves from the Groove MIDI Dataset (Magenta, Google; CC BY 4.0); jazz patterns from the Weimar Jazz Database (The Jazzomat Research Project; ODbL); piano samples from the Salamander Grand Piano (Alexander Holm; CC BY 3.0). Bluetooth: the Bluetooth button next to the MIDI status opens Apple's Bluetooth MIDI view to connect an instrument; that is the only use of Bluetooth. The app plays with the silent switch on, as a music app, and keeps the screen awake while it is open, because it is played from an instrument rather than the screen.
