I have just completed my second retrofit. I took a 1980 Schantz three manual console and installed Version IV Hauptwerk software and electronics. The organ is powered by a MacPro dual quad core ( 32 gigs of RAM) computer ( three hard drives and over 20 organs installed). All of the manual presets and all of the toe pistons are functional as are the three balanced swell pedals. The audio system is six Definitive Technology SM450's throug a 750 watt Marantz amplifier with a separate Supercube II subwoofer. The sound is mind boggling !!!!!!
My next project is a three manual drawknob Austin console. I will retain the function of the stops so that the organ will be a fixed specification. The audio system will be the same as above.
