With tools like the VP4 and HX Effects, why have there been no modern advancements in 4CM cabling tech?

You have to be going trough quite a few hops to have latency issues worth noting. Using a polyphonic pitch shifter is a great way to introduce a lot of latency.

I disagree with this.

Run the Oblique Audio RTL tool on your computer to get the real rtl latency at different buffer sizes. (What is reaported by your daw is often wrong and optimistic.) While playing an amp sim, change the buffer size and you will get a realistic picture of what each latency feels like.

IME, ~5ms is acceptable. I can't really detect it below 4ms. Anything in 7-10ms range feels junky. 20ms, might as well not bother.

What this means from a guitar gear perspective, is that a round of conversion should have ~2ms of latency or less if you plan to use the loop. 2+2=4. 3+3=6 (can feel it).

So if you are using a MFX like an FM3/9 or QC (3ms latency), you pretty much cant use the loop.

And if you are using a ToneX, you should run it in series as the first device in the chain (not in loop). And if you are using standalone digital pedals, they should probably be run in series with analog effects on a simple pedalboard, being mindful that they add.

Some people claim they don't care about higher latency, and that is a possibility, but there are other people who can feel it. Also extra latency is more than just standing a few extra yards away from your speaker. That horse has been beaten to death and not worth rehasing.
