The record

Purpose: The plugin converts music into MIDI files for multiple instruments directly in a digital audio workstation.
Instrument detection: It can detect up to eight instruments, including vocals, piano, drums, bass, guitar, synthesizer, strings and wind instruments.
MIDI output: It generates unquantized MIDI containing recognized melodies, chords and rhythmic patterns.
Workflow: Users drag audio into the plugin and drag generated MIDI back into their DAW.
Plugin formats: The plugin is available as VST3, AU and a standalone application.
DAW compatibility: Klangio says the plugin is compatible with all DAWs.
Free preview: The free preview mode can be used without a stated usage cap and lets users view and play back generated MIDI before upgrading.
Export limitation: The plugin exports unquantized MIDI only; other note formats are offered by Klangio Transcription Studio.
Internet requirement: An active internet connection is required because audio is uploaded to Klangio AI for MIDI generation and returned to the device.
Accuracy limitation: Transcription accuracy depends on audio quality, instrument count, mixing and effects, and the page notes that the AI may struggle where a professional would.
Use cases: Klangio describes using the plugin to layer recordings, reshape sampled music and turn performance sketches into editable MIDI.
Support: The product page directs users to a Help Center and Support Chat for answers and issue resolution.
Security and compliance: The plugin requires audio uploads to Klangio AI, and the product page does not state a security certification or compliance standard.
Company: Klangio GmbH says it is a music software company based in Karlsruhe focused on AI-based music transcription tools.
Price from: $0.71/mo
