Improsax

Choose an original study or import a chord chart as text or JSON. Ideas follows the harmony; Solo provides three repeatable takes; Exercises offers six graded drills. Set a practice span, transpose the concert key and select your instrument's written range.

Play auditions accompaniment on MIDI channel 1 and the practice line on channel 2 through the selected preview instrument. Pause retains your place and releases held notes. Export saves the current practice material as a MIDI file. Instrument presets control notation and register; choose the playback sound in the host's MIDI output instrument selector.

The public module includes original educational studies. Imported charts use the same preparation and playback path. PDF, images, MusicXML and encoded iReal links are unsupported; direct-file URL imports depend on browser CORS. Native and plugin formats are not qualified.
