Production Guide: Integrating Converted MIDI into Your DAW
Learn how to route separated tracks, avoid common transcription artifacts, and achieve professional musical results.
Channel Routing in FL Studio & Ableton
When importing our Standard MIDI Format 1 files, always choose "Import separate tracks". This automatically routes Track 1 to your lead synth, Track 2 to your polyphonic pad or piano VST, and Track 3 to your sub-bass channel without messy overlapping notes.
Acoustic Vibrato & Dynamic Velocity
Our deep learning engine extracts realistic velocity contours rather than flat 100-velocity blocks. If driving physical modeling synthesizers or acoustic sample libraries, enable dynamic velocity sensitivity in your plugin settings for expressive phrasing.
Eliminating Audio Ghost Notes & Clutter
For optimal transcription fidelity, avoid files with heavy cathedral hall reverb or intense stereo chorus. Clean, dry vocal takes and distinct acoustic instrument recordings yield over 92% pitch accuracy straight into your piano roll grid.
