I recently built a new PC - Giga-Byte Aorus Elite board, Intel I-9 10850K, 32GB RAM, Sapphire Pulse Radeon RX 580 8Gb, RME Fireface UCX via USB.
Seemed to be working but today using Cakewalk all keyboard input is delayed to audio by around 500ms (hit key, wait for sound), and when I click on a midi note on screen (PRV) the sound is delayed 500ms or more.
RME Firmware update done, current USB Driver installed (18.104.22.168 dated Jun 2019)
Tried PreSonus Studio One 5 to see if problem existed there too. No delay between note trigger and audible response.
Anyone have any ideas?
