Jalmus is a free, open source
music education software helping the musicians,
specially pianists, to improve their sight-reading. You
can train to read music with both exercises on notes or
rhythms.
New in v2.1
Bugfix: turn off keyboard sound.
Bugfix : Tempo settings for rhythms reading.
Bugfix : “route” keyboard sound to an
external midi device to avoid latency when
playing notes.
