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. AUv3 PLUGIN Use MicrotonalLab as a plugin inside GarageBand, AUM, Cubasis, Drambo, and any AUv3-compatible host. The full step sequencer, tuning system, and SF2 instruments are available directly in your DAW. Record sequences as MIDI regions with automatic tempo sync. 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 piano, strings, marimba, vibes, bass, pad, flute, or synthesized waveforms. 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 16-step sequencer with microtonal note assignment per step, velocity, gate, and swing control. Syncs to the host tempo in AUv3 mode. 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 world scales from dozens of musical traditions, including Arabic maqam, Indian ragas, Persian dastgah, Javanese gamelan, and many more. Preview any scale, then activate it across all views with one tap. TUNING SYSTEMS Switch between 12-TET, 19-TET, 24-TET, 31-TET, and 53-TET. Full access to all scale degrees in the sequencer for every tuning system. 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.

Verdict
The clearest difference is price: Virtual Guqin at Free against Microtonal Lab's $6.99. Virtual Guqin also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.0 vs 18.0). Microtonal Lab's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
