sounds like the rich reverb that it is, and it is a “mix-friendly” optimization.
It is important to distinguish between Reverb Time RT60 and Convolution length. The
ear is more sensitive to the slope at the higher gains, so while shortening RT60 will
sound like a smaller reverb, shortening the Convolution length will simply sound less
linear at the lower IR gains.
IR-1 HTDM
There are two different Digidesign stream managers (HTDM Enablers), and the one that
many HTDM Instruments install and use is 128 rather than 512. For better performance
with IR-1 the 512 Stream Manager is required.
