UJAM Basses ver 2 now drag export the midi pattern of current chord, I asked them to put the pattern and chord name in the file name.
I think they will have the same for Guitars and Drums soon.
The good thing with them is that they are session players playing the phrases as well as having a sample set of the instrument.
Watch for EZBass out soon.

The new RapidComposerVST beta has audio tracks as well as midi tracks in the VST. You can create phrases for any virtual instrument containing the keyswithes, they can be moved and will automatically fit any chord/scale. You can use it in Biab with Element as you can't chain midi plugins in Biab. It will import the BB Chord Output midi track.
