So I think here it is the change in latency that is the more important factor rather than purely the larger latency. I think you would also get a similar experience if you were skilled with a high latency instrument and you were presented with a low latency version of the same thing.
This is because a musician automatically learns to compensate for latency by playing all notes in advance. All musicians do this, but usually having more to do with latency of the muscles and nerves. When the latency is changed, the musician has to retrain to a different compensation delay, and that's more tiresome than not having to retrain.
Being (or having been) a clarinet/sax player myself I don't believe it's the retraining that's tiresome here. It's the "not being trained correctly" that's tiring.
Compensating for latency or jitter on instruments like a piano or the drums means to hit the key or cymbal at a different time, but not to hit it harder.
On a wind instrument compensating in theory would only mean to remove the tongue from the hole or the reed at a different time to make way for the stream of air coming from your lungs, but there's more to it:
Generating sound on a wind instrument requires a certain air pressure. Now if the latency a player is used to suddenly gets bigger, it may feel as if the air pressure generated isn't high enough anymore to generate a sound immediatly. Unconsiously one may try to raise the pressure to really force a tone to come out of the instrument, when all that would really be needed is to remove the tongue at an earlier time. This also means that the playing in general becomes louder as happened in IOhannes' case and I'm sure that's what was so exhausting.
Yeah, that does sounds like a very plausible explanation. It is definitely an interesting question, but unfortunately, many of these things are hard to test. Perhaps we can start some Pd patches for these tests. I think this kind of thing would really benefit from free software collaborative development.
