## What is MRT2 Studio?

MRT2 Studio is an on-device AI instrument for creating evolving instrumental music in real time on compatible iPhone and iPad devices. Download the model files once; generation then runs locally, with text always optional.

• Hum an idea, import an audio reference, or guide with MIDI
• Arrange Intro, Verse, Chorus, Bridge, and Outro sections
• Shape genre, lead, bass, texture, drums, tempo, temperature, and CFG
• Record and share stereo 48 kHz WAV files
• Core local generation, all three control methods, recording, and WAV sharing are free

Privacy: prompts, audio, MIDI, and files stay on device during generation and are not sent for cloud inference. Pseudonymous product analytics and crash diagnostics use PostHog EU by default; they exclude prompts, audio, MIDI, file data, prices, and transaction IDs and can be disabled in Tools > More. No tracking.

MRT2 Pro is an optional auto-renewable subscription. It unlocks extra performance scenes and separate MIDI and drum CFG controls. Monthly and annual plans provide the same Pro access; eligible users may receive a 7-day free trial of the annual plan. App Store displays price and eligibility before purchase.
