midi-tuutti

A midi player for playing backing tracks while practicing.

How To Get It?

See Releases for experimental builds. Download one for your operating system, unzip it and:

• On macOS: Run image/bin/midi-tuutti
• On Linux: Run image/bin/midi-tuutti
• On Windows: Run image/bin/midi-tuutti.bat

For developers: see build and run instructions below.

Current features

• Mixer (controls note velocities instead of channel volume)
• For each mixer track, show instruments in a tooltip
• Click track that can be muted in the mixer
• Tempo multiplier (adjust song tempo by a multiplier)
• Constant tempo (override song's tempo)
• Jump to next/prev measure
• Remember latest program (instrument) changes, pan, pitch and other channel specific adjustments at the beginning of each measure. Meaning: even if you skip measures, these adjustments are not skipped.
• Repeat infinitely
• Keyboard shortcuts
• A bit unreliable playback

Keyboard Shortcuts

• Play/stop - space
• Prev/next measure - left/right
• First measure - home
• Tempo adjustment or fixed tempo up/down - up/down
• Switch tempo mode - ctrl + space
• Switch between player and mixer: tab
• Mixer controls:
  • Tracks 1-10 - 1/Q to 0/P
  • Tracks 11-16 + click - A/Z to J/M
  • Example for track 1:
    • volume up - 1
    • volume down - Q
    • toggle solo - shift + 1
    • toggle mute - shift + Q
• Full screen - f11

Midi Devices

Currently only the default Java Runtime midi device is supported. You can get better sounds by copying a sound bank to $JAVA_HOME/jre/lib/audio. See Java Sound API: Soundbanks for details.

Ideas

• Remember last n files
• Select click sounds
• Play click for one/two measures before playback
• Skip empty measures (ones without any notes) at the beginning of a song

Enable engine trace logging with: -Dmidituutti.engine.trace=true

TornadoFX layout debugger: ctrl+shift+d

Build a jar with: ./gradlew build
