In BB 2016 I'd like to use the plug-in Antares Harmony Engine to add audio harmonies to a vocal track. BB accepts this plug-in that works very well when using some presets. When using Midi Omni or Midi Cahannel, it does not work. In other words: I'm unable to send midi data of BB Harmonies to the input data channels of Harmony engine.
Is there anyone who can help me? I apologize for my bad English.Thanks.

PG Music added some midi routing functionality during 2016 so it is important that your version of Band-in-a-Box is current. The current English language build is 438.

Summary of Changes for Version 2016 Build 438 (Sept 12, 2016)

Added: Improved support for time-based VST plugin features. VST plugins (such as JamStix, Addictive Drums, EZ Drummer, and RapidComposer) were previously not receiving MIDI synchronization information from Band-in-a-Box (eg. tempo, play/stop, song position, loop positions). This allows, for example, plugins like JamStix Virtual Drummer to generate and play drum arrangements in real-time.
