Senior Music Transcriber — MIDI & Notation (Generative Music)

Mercor is hiring senior music transcribers to produce multi-track MIDI transcriptions of full compositions for a frontier generative-music AI lab.

This is the highest-skill music-understanding work: separating the parts, identifying every note — its pitch, timing, and velocity — and the underlying harmony, then writing them down as symbolic ground truth, one instrument per track and aligned to the audio.

You'll:

• Transcribe full mixes (or provided stems) into accurate multi-track MIDI
• Capture pitch, onset, duration, velocity, harmony/key, modulations, and polyphony
• Follow a consistent MIDI spec (quantization, tempo map, drum mapping, pitch bends)

You're a fit if you:

• Have professional transcription / notation experience (session work, arranging, engraving, or equivalent)
• Are fluent in a DAW or notation tool (Logic, Cubase, Reaper, Pro Tools, Sibelius, MuseScore, etc.)
• Can transcribe polyphonic, multi-instrument material accurately by ear
• Have strong music theory (harmony, voice leading) and rhythmic precision

Details: Remote · flexible hours · a sample transcription for calibration before staffing · background check + confidentiality agreement required.
