Hello. I am trying to setup my band (4 vox, 2 guitars, bass, eletronic drums, acoustic guitar) through a Signature 12 MTK mixer and Studio One 5 Professional - the flow is: instruments into the mixer (direct mics for vocals, mics on the guitar amps, bass and drums direct in the mixer, acoustic guitar direct when needed); mixer multi-track into Studio One through USB; output from Studio One back to the mixer (not sure if only the main stereo output from Studio One or each channel separately); and mixer to the PA using regular XLRs to 1/4 cables.
My problem here is latency - the input latency into Studio One is ok (9ms) but the output latency is 20ms. I presume this is the latency before plug-ins, which is 6ms itself, so if I am correct the output latency is 26ms and this is noticeable to us during performance as we hear ourselves on the PA. So I wonder what to do here, as I don't want to reduce the plugins, and unfortunately the driver for the mixer interface does not give you a lot of options to reduce buffer size - in the Signature driver, is either 256, which is what we are using to give us these latencies, or 128, which is unworkable because the computer crackles like crazy (there are higher and lower options of course but they won't work).
So, unless I am doing something wrong on the flow above, what would be best solution to reduce the output latency? Add CPU? Add memory? Both? Or neither? Is latency purely a function of buffer size, meaning I would only be able to reduce it if I can juice up the machine so I can use 128 as buffer size? Or is the output latency related to Studio One feeding 4 channels back to the mixer when I only need 2?
I am running Studio One on an MSI notebook with Windows 10 64-bit, Core i5-10300H, with 8GB of RAM and SSD drives.
