Speed Trainer

Break down challenging songs into manageable slower loops.

The app ships with an example song and loops. Explore that first to see how Speed Trainer works.

Add Your Songs

Multiple ways to import music.

Drop files via Files app or Finder: place your audio into the “Speed Trainer” folder for Music Practice Toolkit.

You can also add from your on-device music library, record audio directly (grant microphone access), or use Wi-Fi upload. For Wi-Fi upload, enable the option, type the provided address into a browser on the same network, and follow the instructions.

Sharing Loops

Perfect for music teachers.

Each song file has a matching .json file describing the loops. Share these files together; the .json must have the same name as the audio file.

Share a single song by opening it and tapping the export button. To share multiple songs, use the deck selector icon on the main list to pick several items, then export.
