The latency problem...<br>> <br>> On one hand it is, indeed, a difference. The computer gets some data<br>> in, in chunks, process it, and sends that back to physical world.

With 1024 samples of latency I notice some delay. Below I<br>> don't notice anything. 256 is fine. Go down to 64 and it's psychologically<br>> similar to no delay at all. There were links about latency issues on the<br>> lists a few weeks ago. So yeah, latency. But below a given threshold you<br>> don't feel latency at all.<br>> <br>> So there again, just try and see/hear what happens. I am personally not<br>> disturbed by a bit of latency (a bit being 256 samples at 44.1KHz).<br><br>OK I admit personally I don't play guitar but have done some recordings for people in the past.<br><br>I can generally agree that with a reasonably modest computer (doesn't have to be the fastest in the world) and a half decent soundcard, just using one or two not-too-intensive effects you can usually get away with monitoring through the effected chain of the PC. If you are going to do this I would suggest using a more simple chain to give the idea of the sound you are after, record the dry (or both) signal(s) and then you have the option of applying more CPU/latency intensive plugins once it is recorded, yet you can monitor with at least an idea of what it will sound like, rather than monitoring dry.<br><br>I also have to admit so far I haven't played much with the effects available on Linux. Still trying to get myself migrated from Windows but little niggles often pull me back to the dark side...<br></div> </div></body>
