The main purpose of NoteTrainer PRO is developing the ability of quickly reading and playing notes "at sight." The program generates a random sequence of notes in the range selected by the user, and controls the speed and accuracy of their playing. Instead of random notes can be loaded not very complex melodies in MusicXML format and practice by studying them. Input the notes possible not only with MIDI-keyboard, but from the PC-keyboard, as well as using the virtual keyboard.

ChordEase makes it easier to improvise over complicated chord progressions. No matter what the chords are, you can play as if they were all in the key of C. You don't need to play sharps or flats, because ChordEase automatically adds them for you. Though ChordEase is intended for jazz, it could be useful for any type of music that modulates frequently. ChordEase alters your notes in real time in order to make them harmonically correct, while preserving their rhythm and dynamics. By delegating rapid music theory calculations to ChordEase, you gain freedom to concentrate on other aspects of improvisation and performance, such as feel and aesthetics. ChordEase is a translator that takes MIDI notes as input, and produces MIDI notes as output. The input notes are mapped to the current chord scale in various ways, so that the output notes fit the chord progression of a song. Multiple performers can play through a single instance of ChordEase, using any number of MIDI instruments.
