The other day I noticed that after a bit, my ADC would start sounding like it was permanently bitcrushed, but everything else in my patch sounded fine. The CPU got a bit hot (up in the 80% (activity monitor) range). Even if I let my polys go back to being muted and the CPU came down to 40% or so, the bitcrush sound stayed until I restarted Max.
When speaking to some colleagues today (PA Tremblay and Alex Harker) they commented that they had experienced something similar, and that it was really difficult to pinpoint for them. They suspected it was some kind of bug, but hadn't gotten further than that with it.
It happened to be about 3 times in a row on the same day, and since my patch can really suck up the CPU I attributed it to that, but they said the experienced it under much lower CPU loads.
I've pushed Max into broken sound before, but usually all of it goes weird, but in this case it was literally only incoming ADC audio that got jacked. Everything internal sounded/worked fine.
Anyone experience anything like this?
