I would kill for some proper VST emulations of old home organs. As in ones that I could hook up a MIDI organ to and play with 2 manuals and bass pedals, operate an automatic rhythm unit, make registration changes on the fly, and has presets for whole organ setups. Hauptwerk is cool but doesn’t cater for the cheesy end of the organ spectrum, and the other organ VSTs are usually set up for single-keyboard use.

I think Arturia should get on it and release a full-on Grandma Organ V collection. They’d sell dozens!
