Does anyone know of an expression map for the Spitfire Union Chapel Organ? I picked this up a few years back, but have shied away from any sort of organ writing. But a composer friend has gone through the looking glass and I’ve volunteered to help him get an acceptable render.
I revisited the organ, and it’s pretty nice–3 manuals and pedal–with a decent number of available stops and the ability to place them in any combination (keyswitched). A complete expression map would be a pretty complicated thing, with all the permutations. And of course there would be a ton of playback and playing techniques required. I’ll probably do a simple subset to get through this little side-project.
But I wonder if anyone has tackled this before. I don’t mind being lazy if I can 
Thanks,
Michael
