Editor: MFX Harmony is a MIDI effect/plugin that can be used in any Cakewalk (SONAR, Music Creator) version that supports MIDI effects. It adds auto-harmony and extra voices to a single tone melody. The harmony follows chords that are placed in text events in the track.
After installation the plugin will become visible in Cakewalk in the list of MIDI effects with the name "Harmony". MFX harmony is used in non-realtime, that is you apply the effect on a track and after it is finished you can play the modified track. If the concept of realtime and non realtime usage of effects is not clear to you then please read about this in the help file (mfxhrmny.hlp).
Before you apply the effect, you must place chords in the track. These chords tell MFX Harmony which harmonies it can add. They are placed in text events (use the eventlist in Cakewalk) and have the prefixes "chord:".
