Thanks Al. By the way, Notes is correct about how it works, but BIAB makes it easy using the .PAT file, this way:

1) Right-click on a track name in the BIAB Mixer
2) Select MIDI PATCH
3) Select Higher Bank Patch (from .Pat file)
4) if you don't have one loaded, or it's the wrong one, find the one for the Ketron and then click the UPDATE button
5) you should now be able to scroll down through the patches.
6) caution: I don't know about the Ketron, but many of these .PAT files (I've written several)do not work correctly if you select an instrument at the top left, rather than leaving it at ALL PATCHES

And of course, before you do any of that above, go into BIAB Preferences, MIDI Output Driver, select the Ketron as the MIDI Output device, and uncheck the DXi box if it was checked. In the pull-down for Synthesizer/Sound Card, I don't think you will find an entry for the Ketron, so just select General MIDI Instrument Misc.

Questions/problems? Let us know. I don't use a Ketron so my directions are general. Others here are using it, though, and may have better ideas for the settings.
