I don't totally agree with you. As an amateur musician I'm regularly reading the Logic Users List and can tell you than many people here have good computer knowledge and some are also developing using core audio. Dennis does not ask for a marketing arguing about Logic/Mac versus Cubase/Windows but for *technical* explanation about a latency problem that according his observations exists on the Mac platform and not on the Windows. I cannot say anything about the window's side, but I myself have an annoying feeling when I play my guitar live through M-Audio FW410 + Logic + Amplitube, or Garage band + Amp simulator (even with small buffers). *If* the problem is really the latency added at some points in the chain, then that technical aspect - where is the latency added and how can it be minimized - deserves to be discussed here in order for involved developers to be aware of that potential issue and do the corrections if any.
<x-tad-bigger>Thank you for listening!!
Here are some more numbers
Somebody else (Stefano Bartolini) did some testing few months ago using the same measuring techniques I used to compare between a apogee ADDA running through RME digiface on a WIndows Machine and the same on a Mac.
Sample Frequency used : 44100 Hz
OSX (TIPB 667) & LPX 5.5
DIGIFACE+ADI8-PRO : 64 buffer size 316 samples 7.1 msec@44100
Windows XP + SP1 installed
DIGIFACE+ADI8-PRO : 64 buffer size 219 samples 4.8 msec@44100
The tester in this case was using an Apogee ADDA which appears to be a couple samples faster than John and I's RMEs but otherwise the 103 sample speed discrepancy between the windows machine and the Mac machine is there for all to enjoy, er, well, to experience.</x-tad-bigger> _______________________________________________
