What Transkr is
Transkr converts monophonic and polyphonic instrument audio into musical information such as notes, melody, harmony, and rhythm. While you play, it outputs MIDI events and shows notes, intervals, chords, key, and tempo in real time; it can also transcribe recorded audio. Supported sources include guitar, bass, voice, piano, violin-family instruments, and saxophone, with suggested guitar and bass finger placement. You can import WAVE, AIFF, or MP3 files and export Standard MIDI File, MusicXML, or compressed MusicXML (MXL). Features include polyphonic pitch detection, beat, key, note, and chord tracking, plus a polyphonic tuner. Transkr is available on macOS and Windows as a standalone app or DAW plugin. Setup guides cover major DAWs including Ableton Live, Logic Pro, Pro Tools, REAPER, and Studio One Pro. The 14-day, all-feature trial requires no credit card. A perpetual licence costs 99.00 USD once at the introductory price, regularly US$129, with lifetime free updates and no recurring fees.
