 The keydesk of 4/89 Mighty Allen Digital Church Organ.
The console of this fine organ is custom made to order from exotic woods. It features a Moving Combination Action and multiple levels of memory. The house organist for the All Faith Chapel, Raymond Blume, had this to tell us about the 4/89 Mighty Allen Digital Church Organ. We quote him in blue text below:
The organ has 89 stops, with the capability of adding more stops to a Division, selected from one of the three Voice Expander modules. Only one stop per Division can be attached through these MIDI modules. Of the three expanders, the two external units are currently in the process of being hooked up. The other expander is built into the console of the organ on a pullout below the manuals and is the only one speaking at theis time.
Only 4 Divisions can be selected from the expander, so a judicious choice of Divisions gives the best results. There is a shared swell shoe for the Great/Pedal Divisions. There is another set of speakers located on either side of the cross in the front of the Chapel, so altogether, there are 4 locations of speakers. The balcony speakers are accessed from the Antiphonal tilt tablets, with the exception of the Choir, which is accessed from a drawknob. The Antiphonal speakers can be used alone or in tandem with the Main speakers, or Main speakers alone.
What I find even more rewarding and useful are the four 32-foot Pedal stops, including a Contra Bombarde. The instrument is divided into six Divisions: Great, Choir, Swell, Solo, Pedal, and a Floating String Division. Couplers are more than adequate for an instrument of this size. The Great/Pedal, Choir, and Solo Divisions can be used in an unexpressed state.
There is the capability, with a tilt tablet, to change the "tuning" of the instrument, as well as one which can choose between a church type organ tremulant and a theatre type organ tremulant. There is a full set of toe studs. The left side studs duplicate 10 of the General Pistons, and the right side studs are devoted to controlling the Pedal stops and the manual to pedal reversibles, 32 foot reversibles, and the 2 different tuttis. The reversibles are duplicated with thumb pistons. There are a number of other controls for special uses.
The organ has 16 programmable and lockable memories. The MIDI from the expanders work on a modulus technique, so that the expander settings programmed into, say Memory 1, will propagate to other pistons. I believe this is modulo 4, but I've forgotten that information. I've found this to be problematic when more than one person is programming memories, as another organist can change the registrations on any of the MIDI inputs from the expander, and it affects all the other inputs on that modulo.
When we first got the organ, it was like having new rules for most everything (and we graduated from a 3-manual Allen Organ). Many facets of the instrument are not readily apparent, and I think, are learned only by experimenting and playing the instrument. I agree with your description of it as being a Mighty Allen, because it is just that. And to think, the new Allen Organs have made improvements to this instrument we have today.
I enjoy the theatre organ, but have spent the past 46-plus years playing in churches, so I never had the time to develop any theatre organ techniques. Perhaps you can give me some instruction. If I should become passable at it, I might even want to join the theatre organ group.
 The left stop jamb of the console.
In this picture, we are looking at the left stop jamb of the console which houses the Pedal, Swell, and Floating String Divisions. Note the two Allen Voice Expander Units and the Recording Computer. The original 89 rank disposition, equivalent to approximately 100 ranks, can be expanded further via these expanders. One might say there are 300 ranks available, although the same stops are available on each expander.
One of the many unique features of this organ is a Floating String Division that can be coupled to any manual or the pedals. It can be coupled to any of the other divisions, but it does not propagate. For instance, if the Strings were coupled to the Swell, coupling the Swell to any of the other Division will not couple the Strings. If you want the strings to be available on several divisions at once, the Strings drawknob must be pulled on in each division.
To the left of the console are three black boxes attached via MIDI. The top two are the external Allen Voice Expanders. Beneath the two expanders is an Allen Performance Recorder, which allows an organist to record what he/she is playing and then play it back, including all stop knob and expression pedal changes.
 The back rail of the console.
Here, we are looking at the four manuals and the back rail containing the intradivisional couplers. Note the dozens of pistons below the manuals. The interdivisional couplers are on drawknobs in each division.
 The right stop jamb of the console.
Finally, we swing around to the right stop jamb of the console which houses the Great, Choir, and Solo Divisions. The third voice expander is built into the organ and its controls are housed in a drawer under the stop jamb.
Raymond had this to add about this fabulous instrument. We quote him in blue text below:
There are some other things that are interesting about the instrument.
The Swell, Great, and Pedal Divisions have second voices on some of the drawknobs. These are controlled by another drawknob in the affected division.
On the Swell, it is the English Swell. On the Great/Pedal, it is second voices, which affects both the Great and the Pedal.
There is a Zimbelstern, operated only by a toe stud on the right side above the General Toe Studs.
There is a Choir Unison Off coupler that didn't immediately seem useful, but there are certain registrations which can take advantage of this. For
instance, if one wanted to couple Choir stops to the great, such as flute, viole, flute 4, octave 2, but wanted to use the expander to provide a clarinet alone on the Choir. The Unison Off would suppress the Choir setting, but still couple it to the Great. The expander would provide the clarinet, which isn't affected by the Choir's Unison Off coupler.
