Hi all, I am Francois, french guy who studied organ and some more in Versailles, then BA of sacral music in Germany, worked as Kantor for years and now organist of the Cathedral of Bogotá, Colombia. Electronic organs were for me till now tabou, but at least as a practice organ, I can only say yes to myorgan and Stiehr-Mockers. Projected configuration, smthg like an old computer, two homemade manuals with the electronic of Casios CTK-2100 (they have usb, yeah), Pedal homemade (no problem with woodworking, but what a thing the calcs for a radial-concave BDO!) with Casio MA-150 (!) and no name interface, a good sound card, 2 good but not too expensive medium-high speakers, one homemade bass spk and homemade console. Well, I know I could make it much cheaper in using MIDI-Electronics for the keyboards and Pedal, buuuut there is no way to get this kind of special electronic in Colombia!!!
