## What is Microtonal Lab?

Microtonal Lab is a complete microtonal music studio for iOS. Break free from the 12-note octave and explore the infinite space between the notes.

HARMONIC GALAXY
Discover musical intervals as a visual universe. Every dot is an interval above the root — its size shows consonance, its color shows its position in the octave, and its number shows the exact distance in cents. Pinch to zoom and new microtones emerge from the depths. Build custom scales by tapping intervals and save them to your library.

MICROTONAL KEYBOARD
A fully playable keyboard with exact microtonal tuning. Choose from sine, organ, pad, or jazz piano sounds. Activate any scale from the library and the keyboard reconfigures to show precisely those notes. Supports glide between notes for expressive playing.

STEP SEQUENCER
A 32-step sequencer with forward, reverse, ping-pong, and random playback modes. Assign any microtonal degree to each step, set velocity, and control tempo with an XY-pad FX section for filter, reverb, and delay.

LAUNCHPAD
A grid-based launchpad for live performance. Rows correspond to scale degrees, columns to time — tap to toggle notes and play your patterns in real time.

SCALE LIBRARY
Browse over 100 world scales from dozens of musical traditions, including Arabic maqam, Indian ragas, Persian dastgah, Javanese gamelan, and many more. Preview any scale with audio playback, then activate it across all views with one tap.

TUNING SYSTEMS
Switch between 12-TET, 19-TET, 22-TET, 31-TET, 53-TET, and just intonation. The app auto-selects the best tuning for any scale you activate.

MIDI EXPORT
Export your sequences to standard MIDI files with full microtonal pitch bend on each channel. Import directly into any DAW for further production.

FX
Filter (low-pass with cutoff and resonance), reverb (from small room to cathedral), and delay — all controllable via XY pads in real time during playback.

Microtonal Lab is built for composers, sound designers, music theorists, and anyone curious about the music that lives between the keys.
