I don't think so, Olen. Only in the Listening Room, which also has GPO demos. I think it would be good if, in that forum, everyone prefaced their subject line with either JABB: or GPO: as I am particularly interested in hearing other JABB demos now.
Or, we could start a thread in this forum for posting demos (or continue this one for that purpose), but I think they should also be posted in the general demo section so more people can find them. I suppose it's up to the moderators how they might want those distributed.
In any case, FWIW, here's my recent demo of some JABB horns used in a rock context - Steve the Superhero.
