Multiprocessor support

[TiUser]

While checking out Rayzoons new Jamstix 3 demo I again fell over hefty timing load spikes when Jamstix gui has been opened.

See discussion on KVR thread:

But it looks like there is not only an issue with Jamstix but Cantabile multiprocessor support too. I start to think Cantabile should work much more efficient on multiple cores than it actually does...

I've just made an experiment and put the latest Cantabile build 2056 on my old Pentum 4 notebook. It works worse to the versions before the audio engine changes.

No clue why but with simple Asio4All @128 or @256 samples buffer I got massive timing load spikes too - with simple plugins like FreeAlpha or B4II - which might use up to 15% on this machine and spiked to over 1000% resulting in massive crackles.

Going back to a pre audio engine redesign version got better behavior - so still showed some spiking but within the load capabilities and without crackles.

Then I got back to Cantabile 1.2 - no that's no typo - the very old version... and there is this spiking in the timing load meter too - about 4-5 times of the basic load.

I ask myself what's happening here... and got the audio engine even worse in the latest incarnations? Or do I do something wrong?

There is some testing going on with Rayzone and Topten!... stay tuned.
