Tracks & Instruments
The Rack is the vertical panel on the left edge of the screen that manages all instruments in your score.
Track Types
Reflow has three track types:
- Tablature — for guitar, bass, banjo, ukulele, and other fretted instruments. Shows fret numbers on string lines.
- Drums — percussion staff with drum kit mapping. Uses specialized noteheads for different drums and cymbals.
- Standard — traditional staff notation for piano, violin, flute, vocals, and other instruments. Supports one or two staves (e.g., grand staff for piano).
The Rack

The rack has two display modes:
- Compact — track icons with solo/mute buttons. Click a track to select it.
- Expanded — full track names, volume/pan sliders, instrument selector, and tuning button. Click the rack header to toggle.
Adding Tracks
Click the + button in the rack header to add a new track. Choose the track type (tablature, drums, or standard) and instrument from the menu.
Reordering and Deleting
In expanded mode, click Edit in the rack header to reorder or delete tracks.
Multi-Track View
All tracks are always visible in the score. Click on any staff to make that track active for editing. Use the rack or arranger to solo or mute individual tracks during playback.
MIDI Instruments
Each track can be assigned a different MIDI instrument for playback, giving you access to the full General MIDI set — 128 instruments from acoustic piano to synth pads. Change the instrument in expanded rack mode.
