Yes, it functions as a MIDI controller for DAWs like Logic and GarageBand, using per-channel pitch bend to maintain microtonal tuning accuracy in chords. ### Does 24-TET Keys: Microtonal MIDI support custom tuning files like Scala? No, the app currently supports 12-TET and 24-TET tunings but does not import Scala or .scl files. ### What is the difference between 24-TET Keys and a standard MIDI keyboard? Standard keyboards are limited to 12 semitones per octave. 24-TET Keys provides 24 equal steps, allowing for quarter-tone intervals that standard keyboards cannot play. ### Are there other apps for playing microtonal music? The developer offers a companion app called Fingerophone for standalone microtonal performance, but 24-TET Keys is specifically designed for MIDI integration. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
