So its not a real pipe organ? So why does it have so much of a delay? Is it the organ or the acoustics? I've never played one with actual pipes, but I would hate to have to play one with a delay.
If I were you I'd be on that hammond every sunday 
all pipe organs have delays because they use air which is forced through a pipe
the longer pipes are wider and longer
and require more air
if you think about a garden hose when you take the gun off the hose
the water just pours out but if you put your finger over the opening you get a faster stream of water
well the bigger pipes have slower moving air because it is a bigger wider longer pipe
so the delay on the manuals is almost imperceptable
but it is still there
but the delay on the pedals is a little more noticable.
so can you play uptempo shouts on a pipe organ
not really
but anything is possible
which is why my (fake pipe organ) and all allen and roger organs have delays
because real pipe organs have delays if you wanted to imitate a real pipe organ you have to program in a delay
otherwise a true pipe organ player will feel he was playing a cheap imitation
for example those theatre organs have no delay at all
and a true pipe organ player will never look at them like they are real
my organ although it uses amplifiers is an organ that today would run a few hundred thousand dollars
precisely because they really made the stops sound like a real pipe organ
in its day it was a very close approximation of a real pipe organ
some of the stops dont sound that good
but with todays technology we could probably update it for about 70 thousand dollars
but I seriously doubt that will happen
actually I do play the hammond every sunday
but not by choice more because the MOM cant play the pipe organ and I think she doesent like the attention I get when I get a chance to play it.
they are different instruments and require a different touch
many of the voicings you can play on a hammond would sound terrible on the pipe organ,
however the techniques that we learn for pipe organ sound fine on the hammond. because the hammond was originally trying to replicate a pipe organ
(they did a terrible job at that)
I find that the more time I spend on the pipe organ the easier the hammond is to play
so you would be cheating yourself out of a free education if you didnt take advantage of such an instrument if you had access to it.
like a few weeks ago I was playing a hammond at a church and started to do a two foot pedal run
and their organist who was a beast dropped his jaw
I am no beast but for that momment I was
and that came from training on the pipe organ
after a while the hammond becomes like toy in comparison
the pipe organ has 4 manuals and four banks of stops flutes reads horns and strings several 8 ft 4 ft 16 ft 2 chimes etc
plus all the couplers
it is like having an orchestra at your finger tips
you can layer horns and strings and chimes on one manual
and have another manual playe a flute and french horn duet on the solo manual
while the choir manual plays a soft string patch
then you can set the pedals to play a flute if you wanted
you are only limited by your imagination,
