Strange, but Mixbus 3 seems to perform at 256 buffers pretty close to the same as Sonar at 128. When using amp sims I of course want the latency to be as little as possible.
Mixbus will not work at 128 here. I get pops in the sound and the dsp spikes out of control, but at 256 it's fine. On startup at 256 it says latency is 5.3ms. I assume this is roundtrip.
Sonar at 128 has 7.3ms roundtrip latency.
After testing this morning they both feel the same to me. Do any of you know how to test this better? I'm not sure where to look for roundtrip latency in Mixbus 3, but I'm starting to think I could actually record with it. If I ever wanted to.
