Shown above is Harrison Organ Works pilot project which started out as an Allen Organ 903-3 digital organ. The original Allen triple computer sound generators will be used for the antiphonal organ and for chorus effects. More digital to analog boards will be added to the Allen computer boards with separate traveling wave generators for each DAC to enhance the original stops. Several virtual organ high speed computer systems will be added with the LCD monitors shown at the top and the additional draw knob side jambs added with reversible virtual draw knobs. Also, 60 ranks of EPROM stored sound generator boards are to be mounted in the amplifier racks. If we use our multi-plexed design there will be 300 Eproms for the 60 ranks with one Eprom memory per octave per rank. The computers will allow the organist to select multiple organs to play at the same time and the virtual draw knob stops (instrument selectors) to select multiple instruments for each stop by means of special organ selector pistons. So, this instrument will have the sound of multiple organs and multiple orchestras playing simultaneously. With 16 second samples of all stored waveforms and multi channel tri-amplified sound system, the reality of the sound should be astounding.
