Actually with his help I ended up changing and fixing a lot of driver issues on the recently purchased used CS3.7. It was a mess when I bought it.
I run the Convolution files he provided on ROON. There is no way I would attempt this Convolution creation on my own. I am very competent on a computer but also smart enough to know what I do not know.
BTW - Mitch mentioned to me that he is looking at DSP for headphones in the future. I want to see what he can come up with for the RAAL SR1a.
