Psychological effects often play a role as well.I think latency is one of those things where if you see a number, it feels bad man. But if you just use the device, you can quite often get away with a lot more than you'd expect. Some electronic drumkits for instance have somewhere between 7-13ms of latency from when you first hit the pad to when you hear your first sound. Very few people complain.
But when I tested the first FM9 prototype in my new studio years ago, I was a bit irritated. I thought something was wrong. My good friend Thomas Blug came by and he also said that there was a lot of latency. It felt strange.
But I also approached the matter somewhat naively. First of all, I had connected the FM9 to my RME FIREFACE with an XLR cable and I had the wrong studio monitors. As it turned out after a phone call with the manufacturer, the (very high-quality) monitors have a total latency of 6 ms. This is partly due to the conversion but also to the elaborate FIR filters. But that is not a reduction in quality. These monitors were developed for monitoring. Who would think that guitarists use them as FRFR?
So the chain looked like this: Guitar -> AD -> FM9 -> DA -> AD -> RME Fireface -> DA -> AD Monitor -> Digital Crossover and FIR Filtering -> DA- Speaker. The RME added about 3-4 ms and the monitors 6 ms. In total, it was over 12 ms. And I can feel that. There is a reason why there are no digital (or only a few) professional in-ear monitoring systems. The industry standard is analog (Sennheiser ew IEM).
How did I approach this? First of all, the monitors were sold and replaced with very high-quality analog monitors without DSP (PSI AUDIO A21). FM3, FM9 and AXE FX III are connected to the Fireface via SPDIF and AES respectively.
Now the chain looks like this: Guitar - AD -> AXE FX III -> AES OUT -> FIREFACE -> DA-> Monitor Speaker. Perfect. ;-)
Live, on the other hand, I usually use in-ear monitors and a digital transmitter. The Sennheiser ew-D adds a latency of 1.8 ms.
But now the signal goes into a digital console that also adds latency and is sent back to my in-ear. In our case, it is usually a Digico S31 console that runs at a 96khz sample rate. This keeps the latency as low as possible. But thanks to in-ear monitoring, the space from the guitar cabinet/wedge to the ear is eliminated, as is the natural latency, so that overall the playing feel is absolutely direct, as you are used to.
In this respect, I don't understand why manufacturers can't manage to build digital inputs and outputs into their devices.
When the FX8 was first released (I'm still a huge fan of this device), it didn't have any digital I/O. That wasn't necessary, since it was designed to work with analog devices. But times have changed.
By the way, when I occasionally ask my drummers if it would be okay for them to play electronic drums at special shows, I only get contemptuous looks.
