<DIV><FONT size=2 face=Arial>Just a little explanation of dpc latency for those
who it might pertain to which is anyone doing audio on the wondows
os.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>DPc stands for defered protocol.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Windows runs important drivers in the kernel where
time is alloted to essential processes.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Windows is not a real time os.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>So timing is everything.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>If you have an errant printer driver, or other
device which is hogging too much time in the kernel, that can bring the house
down, say you've got your daw loaded up with lots of plugs, and real time plugs
want the processor right nowand a few miliseconds can matter
greatly.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Say your guitar cab simm wants the processor, but
your processor is busy dealing with the video driver, guess what, audio
drop-out.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>This doesn't affect office machines, or even gaming
machines, but for real time critical operation, a well tuned</FONT></DIV>
<DIV><FONT size=2 face=Arial>modest machine with low dpc latency will
out-perform a power house with lazy dpc latencies.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Just imagine you have a big shipping truck which
comes one a day.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>That's your pc.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Now imagine you have all these vst plugs, that run
around several times a day, these are your little shipping trucks.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>But what if the big truck didn't come by once a
day, but twice a week.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The big truck can carry way more than the little
trucks can, but if it doesn't come by often enough, then the local shipments
will pile up.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Daw vendors use motherboards, and particular
parts and settings which are known to give low dp latencies.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>And one little thing like a video card, a different
driver revission,</FONT></DIV>
<DIV><FONT size=2 face=Arial>or even any device which wasn't figured in the
equation can bust you down to a high dpc latency where your pc though it may be
hugely powerful, isn't rotating fast enough in the cue to catch all those
processor demands your daw may be asking for.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Other operating systems handle processor calls in a
different way, so this is most particular to windows.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>But even with more modern operating systems like
later versions of linux, you can swap out kernels to say a real time kernel for
better performance.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>But the whole architecture is different so dpc
doesn't apply in the same way it does to windows.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>That why a mac is great at being a mac, but may
such on the windows side for daw duties, unless your not running lots of real
time plugs, if your doing audio loops and mostly i/o kinds of things from disk
then a fairly high dpc latency may not be noticeable, but the minute you
start.</FONT></DIV>
<DIV><FONT size=2 face=Arial>getting a fair number of real time plugs, it will
bite you in the butt.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I'm not sure exactly when the models changed, but
if you read on cakewalk forums and also information from other users and
anything posted on cakewalk for daw performance will be relevant to any other
daw</FONT></DIV>
<DIV><FONT size=2 face=Arial>that's because they all use asio drivers and the
same types of plugs and they're all prone to dpc latency issues.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>But my understanding is the earlier macs did much
better on the windows side than the latest ones.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>This shouldn't affect performance on the mac side
though.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>That's why to my understanding cakewalk isn't
officially supporting their products on the windows side of things
anymore.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>But if you are having good luck and your mac does
well enough for you on the windows side then that's great.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I just wouldn't recommend it as my first choice for
windows daw work.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>But just fine for ordinary things, email, office,
light two track work,</FONT></DIV>
<DIV><FONT size=2 face=Arial>even firing up reaper to slice and dice up audio
should be fine as long as you don't hit the real time plugs too
hard.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Again, it's not about power, but about
timing.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Until I understood this aspect of windows daw work,
I used to pull my hair out, I'd have this great custom shop pc that had all
kinds of power but it's drop out on me if I put too many plugs in
it,</FONT></DIV>
<DIV><FONT size=2 face=Arial>and sometimes it would be that many.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I'd have to freeze tracks to make things work
again.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>But when I started buying machines from Jim
Rosebery, and other reputable daw vendors, that problem went away.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Because custom shops might build you a great gaming
machine, or office box, but they usually don't know the first thing about the
right stuff or how to tune a daw.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>

<DIV>I am also running another machine that is my Mac with a Windows 7 Boot
Camp partition. I also have the best of both worlds, and I am loving it. In
these days, we need to have several tools to complete one job. I will be glad
when we can just sit down at one machine and get the whole thing done without
having to worry about what will or will not work for us.<BR><BR>GF

<DIV><FONT size=2 face=Arial>Xp, old as it is makes you compatible with many

<DIV><BR></DIV>Shift he has nothing to do with the amount of presets in a

What is the VST effect you find limited to showing 130 presets in the
combo box in FX Chaining View, and how many of its effects are shown when
you press shift+P in track view?<BR>> Indi<BR>> <BR>> On
