As most of you probably know, there is a lack of a good program for
providing the relay function to connect the MIDI inputs to the MIDI
outputs under stop control if one is trying to use SoundFonts in a
way that resembles the control of a theatre pipe organ.

A year ago I acquired two Wurlitzer consoles that were is fair to
poor condition and I am in the process of slowly restoring those. My
plan is to restore the electropneumatic combination action and to use
the console to control a MIDI synthesizer to provide the pipe sounds.

I am basing the synthesizer on the Cinema SoundFont from Bruce
Miles. I am writing a program I call the Miditzer that provides the
relay function to connect the MIDI inputs to the MIDI outputs under
stop control. Miditzer has a long way to go but it is already doing
a pretty good job of simulating a Wurlitzer Style 216. There is a
graphical user interface that allows control of everything with a
mouse. I will post a screen shot of the GUI that will give you a
much better idea of what Miditzer does.

Of course, the keyboards are MUCH better controlled by MIDI keyboards
than by using a mouse. I do most of my practicing on two MIDI
keyboards loosely stacked on top of each other driving the Miditzer.
No pedals yet :-( Also, no stop control or combination pistons
except by using the mouse on the screen. No swell control at all
yet. But even with all these unfinished parts, I have been able to
learn quite a bit about TPO registration and maintain my meager
manual technique, perhaps even progress a little.

I will be making Miditzer freely available. I am trying to put
together a web site that explains how to set it up and use it and to
provide a download. If anyone wants to give Miditzer a try before I
get a web site up, just email me or post a message.
