glad to report it even works on AMD phenom II processors!!!

(mine is a quadcore phenomII 955 and works lovely on all 4 cores)
inside reaper /64 bit version

ps: yes that little multithread button took me a little to find it...it's in the "patches" section at the bottom.

Beta build working great here. I7 Sandybridge on pc Windows 7 64 bit. Multithreading working fine. I think I'm in love

The "Master" section is mainly in the "Main" page

. Also in the Patches page so you have access to accuracy, main volume etc. while browsing.

Just found an issue with the multithreading though. Was doing some quick tests since I wanted to see if diva would use the hyperthreads that ableton does not use. So I created 8 tracks with the default patch playing a sustained note. Without multithreading all goes well, just only uses 4 threads. If I create 8 tracks with multithreading on everything grinds to a halt and I actually saw the usage meter in ableton go above 8000%

Haha 8000%! Yowza!

I'm not seeng much improvement on an old Core2Duo but then I don't think there was supposed to be much if any. One request maybe if it is at all possible would be to improve draft mode efficiancy, make it as CPU friendly as possible, and make the default offline when selecting draft mode to 'best'. That would likely get a lot more users more real performance out of Diva until CPUs catch up or other optimizations are found. Again, I have no idea if that is possible or makes sense to do for U-he, but for me personally it would be a great help.

yes sorry it is indeed in the "master" section which is viewable from the main window too.
i was stresssing in trying this beta wondering why the multithreading wasn't working loading all my cpu hungry patches (didn't know i had to activate the multithreading manually)....till i noticed the led "multithread" right there.

anyway for clarity @everyone is just under the Accuracy settings in the Master Section

enjoy

Are you sure it wasn't OVER 9000!?

Sorry! I couldn't resist any longer

Cheers

I haven't had a chance to check out a beta in a while. I definitely see big performance improvement on my Quad i7 MBP, not so much on the dual core machines I use for work. I can't wait till I get home to try it on the 12 core monster MacPro.

Has filter tuning changed? The last version I used was the release build and it seems like patches where I used the filter as an oscillator, are now out of tune. Not a big deal, I need to update my patches anyway, just wondering

Hehe had to look that one up

could multithreading open up the chances for even further advances in accuracy?
great->divine-> bye bye hardware (can't even think of a name for it)

anyway this is the 3rd milestone since diva was released :
1) removed filter feedback lag in software synths
2) removed aliasing from Frequency Modulation (here maybe the extra cpu from multithreading could go and help even further)
3) introduced multithreading for a single instrument

and there might be more...but these are the ones which mattered to me.

clemens deserves a nobel price i think

OS X / Live 8.3 / Core2Duo

(If I'm not confused over something ...) MIDI mapping writes to the midiassign.txt file, but Diva needs to be reloaded for the mappings to work.

Also multi-threading doesn't seem to like a Core2Duo, I didn't have any expectations whatsoever but just figure I'd mention it crackles a bit.

Incredible update! Multi threading works in EnergyXT (which i don't think is multithreaded in the first place?)
It more or less splits the cpu usage on the four cores evenly (hard to say with everything else going on in the computer). With a 16 note polyphony 4 stacks setting i can play four keys without getting crackles. With multithread off i can play one, but not two keys before crackeling happens. This was at divine and a patch with modulated bite lpf and hpf (which i find the crackeliest)

Definitely seeing the same thing with keyfollow on the HPF BITE

Multithreading needs more CPU power (20% for a 2-stacked voices with "great" accuracy) on a Core 2 Duo. May be this "improvement" goes in the wrong direction.

I thought that a plugin couldn't use multiple cores because the DAW handles cores itself (and usually allocates all plugins in a track to same core).

Is it wrong? Or is it voodoo?

Diva update?
