Another issue is when I check a box in the PEQ (usually right after restarting MC), or check any of the main boxes in the DSP Studio tree the DSP Studio loses focus and the main MC window comes up. Very annoying when doing lots of work in the DSP studio.
This happens to me pretty regularly, but (strangely) it only seems to happen when I bring up Holm Impulse. It's like clockwork, everytime I start Holm it starts losing focus whenever I click one of the main DSP modules. I only bring this up because I do most of my DSP fiddling when I'm doing measurements, so it took me a while to realize that was what was causing it. I have to quit JRiver and restart with Holm closed to make it stop.
And that's not the only weird interaction between Holm and JRiver; for example JRiver outputs to a different soundcard than my system default, but when I start Holm, even though it's only interacting with the default sound device, it resets the soundcard that JRiver is playing, which kills playback and sometimes crashes JRiver.
I don't have any more info about the other issues, but I thought I'd throw that out in case you have the same issue.
I'd also offer another vote (+1) for more customizable crossover slopes (odd order filters, etc.); as it is if I want an odd order filter I just dial it in as part of my convolution because rePhase has a lot more crossover flexibility, but I'd rather do as much as I can in JRiver's DSP (without having to use three shelving filters).
