Just tried the tape stop feature...fun! Not sure I'll ever actually use it, but fun.
I was more interested in the new quality modes, hoping the HQ mode might reduce aliasing. I'm not clear on whether "normal" is what's been newly-added, or if it's the "high quality" mode. Whichever it is, HQ does not appear to have any effect on aliasing. It's apparently not an oversampling option. "Normal" generates fewer upper-level harmonics, which accounts for its greater CPU efficiency. So if you're tempted to use "normal" for mixing and "HQ" for rendering, be aware that they won't sound the same.
