No I was not talking about styles. A combo is the association of specific patches for bass, piano, guitar, strings... Until BIAB 2012, there was a button on the upper left corner named "Combo". You could scan through 10 combos
Maybe you got rid of this possibility because it does not apply to real tracks. However when a style is made of only MIDI tracks, it was interesting to try different combos
