For those who cannot, or prefer not to figure out harmony and good voice leading, Cochleor has released Harmony Improvisator (Mac / Win; $129 MSRP), an advanced harmonic composition tool that does all the work for you. The new Harmony Improvisator plugin, previously available from Jonathan Schmid-Burgk, has undergone a major reinvention; it now features Intel Mac support, a built-in synthesizer, a harmonic pattern sequencer, and more.

It creates perfect harmonic improvisation, following the rules of classical harmony theory and counterpoint. According to Cochleor, the plugin is so good that no professional knowledge of harmony or improv is required, so you don't have to worry about double-checking its work. Use the plugin to form complex cadences and harmonic frames for songs, soundtracks, and arrangements, in any style of music.

Harmony Improvisator is available as a VST effect plugin. To learn more, visit www.cochleor.de.
