On my ‘big’ computer, desktop i7, Windows 10, 24GB RAM, Fireface 800, Omnivocal distorts horribly unless I increase latency to the maximum 1024 samples, and then it just distorts a bit! Exported audio is OK of course.
On my laptop, i5, Windows 11, 8GB RAM, onboard audio with ASIO4ALL it’s fine and glitch-free.
That’s weird, I run Cubase on a somewhat old setup (Ryzen 1600AF, 8GB RAM, 1TB NVME, Radeon RX6400 4GB, Windows 10) using Voicemeeter at 256 samples and Omnivocal works a treat, only slowing down when it has to change voice or recalculate all the pitches with text. Maybe something that was setup in Cubase, TotalMix or a combination of both is causing the issue?
