Thanks pipleline. The plugin looks good and I've decided to tackle it. One thing though, In RealBand, when a RealTrack has a RealChart I can get RealBand to generate some midi for the RealTrack also. Although this midi is not meant specifically to drive an instrument, it does often contain some useful stuff that can be used in DAW tracks. I'm not sure that the plugin can make use of the 'Chart' data in this way. Is that the case?
