This problem occurs in my laptop(Dell Inspiron 7000, intel i7-9750H with native Thunderbolt 3 interface, Window 10 20H2, Universal Control is the newest version).
When I turn on the real-time monitoring in Studio One Pro 5.2.1 which is the latest version, there is a noticeable latency from in to out, even if the Buffer size is the smallest(maybe 6 or 8 samples). That's crazy because when I use it in the same way in Studio One Pro 4.6(the latest version of S1 4), it works normally.
I don't hope that I should use the 4th version of S1 when I record sounds with Quantum 2. So why this problem occurs?
My PC(Windows 10 20H2, too. Intel Core i7-10700K) works normally as well.
By the way, can I monitor the recording sounds without latency, such as "Hardware(Directly) Monitoring" in other interfaces? When I using some VST plugins with noticeable latency, I cannot focus on what I'm recording but on the sound delay.
