Gentlemen, I found a July 2005 post by Dave McMahan on the GEM forum where he explained how to use BIAB to create Genesys styles. I copied his reply and it is pasted as follows:

This is fairly easy to do. Here is the basic concept;

First a little information about styles-
The Genesys features up to 8 tracks of accompaniment per style. Each style can contain up to 4 variations, each having a specific accompaniment phrase for major, minor and 7th chords. Each variation has its own intro, fill and ending with specific phrases for major, minor and 7th chords.

The Genesys gives you the ability to create your own custom styles by recording one track at a time into each of the phrases as described above. This is not hard to do, but does take some time and practice to create good usable styles.

Now to your question-
The Genesys has the ability to record incoming MIDI on multiple channels simultaneously. By setting the Genesys to respond to External MIDI Clock and then entering the Style Recorder, you would choose the phrase you wish to record, arm all 8 tracks and then start the external MIDI device, in this case your PC running BIAB and the Genesys will record all tracks coming from BIAB (up to 8) in one shot. All you have to do is be sure to set the proper phrase length (from 1 to 16 measures) and start BIAB at the appropriate location for the phrase you are recording. Do this for each phrase of the style and you are done. NOTE: It is not necessary to create separate phrases for major, minor and 7th chords. The Genesys will alter the major phrase accordingly if a minor or 7th chord is played. However, it is nice to be able to have additional variances when minor or 7th chords are played so it is worthwhile spending some time recording these specific phrases in my opinion.

If you want to give this a try and have any difficulties, please let me know.

Best Regards,

Dave
