Hi,

You mentioned that you go to the StylePicker and choose a new style. Do you mean that you are changing styles at a bar? (i.e. F5 bar settings).

The problems you are seeing are probably a result of changing between a MIDI style and RealStyle in your song. Band-in-a-Box cannot switch from MIDI to RealTracks (or RealDrums) on a single track. There are ways to work around this limitation - for example, you could use two different tracks, one for MIDI and one for the RealTracks part, and then mute/unmute each track as appropriate. Is that what you are trying to do?
