I’m using a HP Pro Book 650 3ghz 4th generation laptop with 8G of RAM. I have a Behringer UMC 404HD audio interface. After about 10-15 seconds of fast chording with sustain using a piano voice, my sound totally breaks and I end up with a loud buzzing sound. Is this my computer being too old and slow? Or is there a setting I need to change. My desktop is about the same spec only with 16G of Ram, and I have no issues.
