Here for comparison are some archival photos dating from the latter half of 2009.
First, with 3 Behringer UMX-61 keyboards in place. Hauptwerk was running from a single core PC under Windows XP with 2 GB of RAM (this machine not in view). Two ancient Mac computers in view - one to left and one on floor - not related to the installation. To the right - assorted analog audio gear, including a Behringer Virtualizer for adding reverb, controlled through the mixer on top of the stack. To the left- an Ahlborn-Galanti 201 archive module, which predates my Hauptwerk experience. On the single touch screen - the Jensen theatre organ. Sitting on the bench - a Korg NanoKey being used as "pistons". The self-built bench dates from 1997 and stood in my school classroom until 2001, hence the acquisition of graffiti. As yet there was no music rest.
A couple of months later, a crude self-built melamine structure to hold an ex-pipe organ music rest is now in place. This same music rest remains in use today, now mounted on an adjustable bracket from Otto Heuss in Germany. The 3rd manual has been temporarily removed. Primitive PC now in view, on right under monitor. Windows XP had by now been tweaked to make 3 GB of RAM accessible. The archive module is still in use. Silver Octopus "Trio" is on the screen which - like the archive module - delivers dry sounds. The quailty of the "Trio" exceeds that of the module, and not long after this photo was taken the module was removed to storage, where it remains. Audio gear is no longer on a separate table. The Korg NanoKey has been replaced by a NanoKontrol. Hauptwerk at this stage didn't have "auto-detect" so configuring the pistons was a tedious process. A second touch screen has been added. There are still no swell pedals, so swells were controlled by hand from the sliders on the keyboards.
To all console builders out there, and especially to those just starting out, take heart. My creation evolved over more than 6 years. There is still further work to do as I intend one day to reconstruct the swell pedal/toe piston setup.
