I have had no luck posting my images via Imgur or Google Photos to this forum (I used to use Photobucket without issue, but I'm not paying them when other resources are available). I'm gonna try Flickr now.
I would like to show what I did yesterday on a whim with the old Dverb 2.0 test on PT 2019.5 and Mojave 10.14.5, it's insane. I had the session set for 48KHz/24 bit/1024 buffer, max 384 tracks in session, one with the test tone, 383 with 5 D-Verbs each and in record. I had it record for 5 mins with no glitches, snaps, crackles, pops or errors all the while the CPU meter was 100% red most if not all the time. Never seen anything like it in all my years here and this was with an Antelope Zen Studio+ hooked up via USB, not what you call a "High Performance" setup for an audio interface.
