Ok folks,
I have liftoff!!
The redirector works.
I have a problem now with latency between the realtracks style and the piano playing the melody via MIDI.
I think the piano is ahead of the realtracks audio. It could be the other way round but I am fairly sure.
Does anyone know how I can somehow adjust the latency for this?
In Band-in-a-Box for Windows there is a latency adjust setting. Open preferences using Ctrl + E then select the "MIDI Options" button. Latency adjustment is in the left column.
