The Riffs are Midi saved in a BIAB format so that they can be used in BIAB but it is very messy and not worth the trouble. However, experiment in RealBand which can import the first Riff complete with Style and Midi backing tracks. Additional Riffs can then be imported by opening separate files for each Riff you wish to use, save as a Seq file and then use File > Load Scrap to bring them all into the same Seq. That is only the starter. Have fun.
