Re: [sc-users] Free and G Verb CPU?

[Scott Worthington <stwbass@xxxxxxxxx>]

1) This is not as extreme, but still produces the same discrepancy. On the new build, this will settle on about 20% CPU, on the older build about 5%. With more complex code, or as soon as other audio starts getting calculated, this is exacerbated. 

(
SynthDef(\verb, {

    |out=0|

    var source = In.ar(out, 1);

    ReplaceOut.ar(out, FreeVerb.ar(source, 0.5, 0.5, 0.5))
    
    }
    
).send(s);
)

(
Synth(\verb, [\out, 0]);
Synth(\verb, [\out, 1]);
Synth(\verb, [\out, 2]);
Synth(\verb, [\out, 3]);
)



2) I'm a newbie to svn updating, and perhaps this is the problem. I'm on OS 10.4 so I used the Xcode projects to build I'm not sure if this is Deployment or Developer. Since then when running svn update I haven't rebuilt the xcode -- all that I saw download were .sc and .html files so I didn't think I would need to rebuild. Is that not the case? While were at this.. should I use the check out option of the update option of svn?

Thanks again!

1) Can you post your problem code?

2) If you built it yourself - can you make sure you built with Deployment mode (not Development)?

Thanks,

I'm experiencing strange CPU things with a recent svn build (8893): both Gverb and FreeVerb take the CPU up to 80-220% and/or kill the server posting Result=0. The same code works swimmingly on an older build I think Josh posted to realizedsound (7885) with the CPU peaking at about 35-40%.

Anyone else having this problem?
