Hello. I am currently using an ART SGX Nightbass with the X-15 Foot Controller. I've had it for about 5 years now. I really like it, but it sometimes does dumb things; like, some of the levels on my presets drop. I have had to redo the levels in them twice within a year. I am otherwise satisfied with the quality of the unit, but I think I am ready to buy something a little more updated. I haven't seen anything new from ART. Are they still in business? I know they are located in Roch, NY. If there are any high grade processors out there that are Midi capable and quick to learn, I would be interested in hearing about them. I heard a rumor that ADA is out of business, and their product was hot in their day.
