MidiSlayer is a desktop app for people who practise on a MIDI keyboard and want to read real notation, not falling blocks. Plug in the keyboard, pick a mode, play what is on the staff, and get instant feedback on every note.
Nine training modes: note flashcards, graded reading keyed to exam grades from Initial to Grade 8, intervals, chords, arpeggios, scale patterns, key signatures, a circle-of-fifths compass and chord progressions. A library of 69 public-domain scores with wait-mode practice, three arcade games plus a daily challenge, and a seven-lesson course for people starting from zero.
Free tier to try; one payment for Pro on two machines, no subscription. macOS, Windows and Linux.
