<div>8 cores max?<br/>
<br/>
Would Ardour use even more, if more cores are running?<br/>

<div>Renoise supports multicore:<br/>

<div>Pure Data is supporting multicore, too.<br/>
<br/>
Of course they all don't "require" multicore CPUs.</div>
<div> </div>
<div>I assume: for<br/>
high samplerates<br/>
+ many tracks<br/>
+ many fx<br/>
+ very small buffer size<br/>
+ ultra low latency<br/>
singlecore performance is equally important as the number of cores?</div>
<div><br/>
<br/>
</div>
<div>What is a wise CPU choice for realtime-on-stage-use with up to 28 AD/DA I/Os streams, internaly more busses, and FX on each track and bus?<br/>
Are 64 samples buffersize realistic in such a scenario? With 96k?<strong> </strong></div>
<div> </div>
<div>As audioconverters, I am thinking about the RME HDSPe Madi FX + madi-converters (SPL Madison? Ferrofish?)!?<br/>
<br/>
Are you experienced?</div>

<span> Depends on how it's used. For example, Ardour allows you to<br/>
set the number of cores used. The default is 'all but one',<br/>
and that makes perfect sense.<br/>

I think that simply limits the number of cores, no guarantee that they will all be<br/>
used. If it runs lots of threads, as I assume it does, then the chances are it will<br/>
use as many cores as are permitted.</blockquote>

<div class="gmail_default" style="font-family: arial , helvetica , sans-serif;">Fons description is correct.<br/>
</div>
<div class="gmail_default" style="font-family: arial , helvetica , sans-serif;">Ardour carefully and deliberately creates as many realtime priority threads for DSP as told to, based on the number of cores that should be used. </div>
