My template that I have spent months working on suddenly has so much latency that live playing is impossible. If I start a new project and add a VSTi the latency is fine. My UR44 buffers are set at 64. I’ve tried 96 and 128 buffers but I get the same result. I logged a support ticket but I thought I’d tap this resource as well. Anyone experience this?
The real culprit was IK Stealth Limiter. As soon as it is enabled latency goes through the roof. I guess it’s really for mastering and not designed to be on the master bus of a mix.
A lot of these type of processors are mainly for mixing or mastering where latency is not an issue. Other processors like multi-band compressors have the same effect. It is because many of them look ahead to see whats coming at them and in order to do that, they introduce a bit of latency. I used to use Amplitude 3/4 for my guitar until I was playing with an archtop and suddenly the slap-back echo of latency was quite disturbing. In the end I bought a Kemper Profiling Amp which solved that conundrum and made Amplitude redundant.
Other thing to remember is that latency inducing plugins have an effect from front to back in terms of signal chain. In older versions of Cubase a plugin that caused latency affected the whole project, now it’s only the tracks that contain the plugin.
But if multiple tracks go to a bus that has a latency inducing plugins however, it affects all tracks that go to that bus. So it’s a good idea to keep those plugins turned off, or out of your master output, at least while tracking.
iZotope’s Maximizers is similar. There are some settings that really tax my system. Best to switch them out while mixing, so that you can hear what’s in the mix, then in once you have the mix where you want it, and are ready to polish it.
Several plugins, like the UAD ones, have selectable tracking modes, where you can limit their latency for recording.
