Just fine here. How about telling us what your system configuration?
My interface presents to windows as multiple playback devices, and as it turns out, the DL-Processor can't handle routing/mixing to multiple devices. So in situations like mine, you need a program like ASIO4ALL or VoiceMeeter for DL-Processor to output to, and those programs have to handle any routing/mixing.
I previously used VM-B as the windows "playback device", then it would duplicate that audio across multiple devices, and then I would DSP each device in EQ_APO (like the mono sub output shown). I could still use VM-B if I wanted, but I would have to output the sub signal on channel C (aka 3), and then route C to L/1 in EQ_APO. I'm not sure if I could do it entirely in VM-B, but maybe, as there is a lot of "bus" settings.
I found another way to do it with my specific interface though, because it presents 1x ASIO device that handles all 6 of its outputs at once. But then it looks silly because I have sub on Main 1/2, and speakers on Line 3/4, so then the VU meter ends up showing sub-L-R, but whatever.
And it's a good thing I didn't rush things the other night, because like I was worried about, pushing that "Test" button sent full volume test tones to the speakers! And that was with the gain slider and windows volume control turned down (it ignored them). Luckily I had gone and turned all the gains down on the amps before proceeding.
