>x86-based SIMD didn't do floats until SSE1 and 3DNOW, but it doesn't

-Which is not what I'm  saying, if you read more carefully. It's not even a
 point I'm trying to make.

> Does MAX/MSP use SSE and/or Altivec in its signal processing ?
-Both are used (on WindowsMax and OSX-Max).

>I think that the client/server separation is very worthwhile.
-I think so too.

>The dropouts are caused by not enough separation and/or by buffer-clogging.
-Completely agree on that one too.
 So are in the context of jMax are we talking about crappy programming or
 crappy design?

>> on the other hand with current dualcore processors becoming standard for

>You must be kidding. Pd already has a separate GUI thread (wish pd.tk).
>The only advantage jMax has, is that all its GUI lives in that thread,
-Indeed. Making it probably a better design, because it isn't in the way.

>whereas Pd does lots of unnecessary coupling.
-Agreed.

>The amount of work left to make Pd cleanly client-server-separated is almost
>nothing.
-So why isn't that done?

>Then there's the fact that at this point, the issue of getting audio
>running fast enough, has already disappeared.
-To what extent?

>If it wasn't the case, many
>more people would spend time on Pd devel_0_39, which can be up to 4 times
>faster than Miller's Pd (except for fft~ in which case it's even faster).
-Maybe people don't find that an issue.

>Bringing in a second processor is thus not that useful.
-Depends what you're trying to do, I guess...

>> I think, by the way, IRCAM could have supported it slightly more
>> decently with their lists.
>What do you mean?
-I remember that many times awkward questions were avoided or not even
 answered. Also that the complete archive has been removed is rather
 odd to say the least.
