I am too, looking for a Convolution Reverb with a nice simple GUI
I would love some with simple GUI like that, but cheaper
" not all the other Convolution Reverbs, with all the messy GUI "
EastWest Spaces , looks nice, but too expensive for me at the moment !
I would really love it, but as the
OP said :
"
I know that Spaces doesn't use the Play engine, however my general concern is just with East West's quality. Their programmers don't seem to be particularly good at making software that works well. Also, their management seems to be in a bit of denial about that fact. They have claimed that certain things are impossible, that are in fact not such as being able to handle fast bounces. "
bad programming, is a " NO GO " for me,
quote on the "
certain thing is impossible " i guess that is a EW statement ?
LOL, well some things can actually be hard to do
but to me that is just : "
we don't know " how to program it
I tried the FXpansion BFD3 demo, sounds great and i really would love it, but :
it drain's CPU and memory of my system that is result of bad programming really.
Yeah i know, too low on ram, bla, bla bla......, but that ain't the discussion here
Point is :
I have tried a lot of software, that run's smoothly on my system
If it do run on a low / mid tech system then it is :
well programmed and optimized, it will also most likely be very stable too.
Actually there is bad programmers in the big Companies too, yes it's true.
I have tried SIR 1, nice interface .....
but it seem due to the fixed latency of 8960 samples can cause trouble in the system and crash it.
It can also be Bitbridge itself ..... , had several experiences
first step is not to use 32bit plugins so you don't need to go through bit-bridge
( JUST NOW AND THEN ) the sound may hang or cause other sounds to disappear, strange !
Statement from the SIR ( SIR 2 ) webpage :
" It offers zero-latency processing with low CPU-consumption and non-destructive audio processing of impulse responses."
I have tried it, and i have experienced similar problems of the audio disappearing, like with SIR 1.
I have tried other Convolution Reverbs, they work and none of above problem's is present at all.
But then again... Too messy GUI
Plz tell if some of you could find a great cheapsimple GUI Convolution Reverb 
Anyway here's some free Impulses :
