<< I wanted to try something new... Here is the scenario: I have arrangement in place, (all RT / RD). I wanted to experiment with some MIDI percussion that are available in MIDI styles of BIAB... So, how do I pull only drums out of pre-made BIAB MIDI style into my own? >>

To pull only drums out of a pre-made BIAB MIDI style, the steps outlined by Pipeline are nearly correct.

Pipeline opened the correct window but chose from the Preset radio button rather than selecting from an existing BIAB style.

I created an all-RT Chord Sheet, forced the drum track to all MIDI, Opened the Select custom midi style for this track... from the Drum Track drop down sub menu. The drum track was selected by default in the Custom Style Menu Window.

I selected Gumshoe.sty, selected drums and the Drum Kit from the Gumshoe.sty loaded onto the BIAB Mixer track and played correctly.
