MIDI Encoders for the DIY'er with a vintage
organ console!
We picked up a dated theater organ and have converted it to MIDI to
run the Hauptwerk virtual organ software. This Rodgers 321A
"Trio" circa '75 is now playing samples from Paramount
Organ Works as well as a variety of classical organ sounds. The Rodgers Trio was a fine
analog instrument for its time and we were pleased to give it a new
lease on life with the Hauptwerk virtual pipe organ software.
The console is virtually empty. The electronics were replaced
by my own MIDI circuit designs, and we've added a couple of swell
pedals and toe studs which wouldn't be found on a normal 321A.
This endeavor was accomplished with a "surplus" organ console, a
handful of new circuit boards, software from Hauptwerk and an existing computer and sound system. The
acoustics of a larger hall are provided by Reaper audio and the
LiquidSonics convolution reverb plug-in.

My latest project is still in the garage awaiting some finishing
touches. This console was an Allen 603-D and was built as a
two manual instrument. I've added the third manual, resizing
the coupler panel and raising the music desk about two inches.
With this project the drawknobs are fully functional. The slot
for ancient punched cards is no longer needed and I am thinking of
having a custom label engraved to repurpose that slot to accept
"TIPS".
