OS deals with the threads, not plug-in, that's why in some cases you can notice CPU usage not spreaded evenly among the cores (no matters if multithreaded or physical). Try to set max poly on few layers, enable few such layers and play more than just few notes for longer moment on keyboard with task manager started in the background.

Hi,

Operating system decides where the threads go. When for example 8 threads consume not as much it can groups them on few logical processors (these ones you see in Task Manager). And it's good because only system knows if there are other important tasks which can be so much time consuming that require core for itself.
When you turn on all layers with a lot of polyphony on each you should see all cores loaded almost equally (because there is no better load available)

Also please keep in mind that when you play and release some notes LuSH takes some time to fully turn off the voices (when there is no significant signal to process) and thus for the measumrent you should just wait a bit before you measure next time and let the usage fall down to have proper measurement results.

We'll share the result of few machines we measured. We of course can test every configuration - it's impossible. When you really feel you should have better results - please contact with our support. It's first update with multi-core support so there is a possibility that something will need to be tweaked in the future.

Hope this helps a bit

Regarding the GUI which can be too big now

we are writing skin functionality which means you can choose the size you prefer (available soon). We just wanted to give bigger GUI with this update (even hard fixed) because moooost of users wanted this

Cheers!

I've gotten a few "locked" parameters so far this morning. Twice with the Delay unit and once with the Unison Voices. The parameter readout displays what appears to be a broken 7 and the value can not be changed:

I had programmed a patch called Mutli Core Test that's designed to push the CPU demand quite high. High Poly, Layers with Unison, Supersaw, Reverb other effects, etc. It is this patch I used to check the Multi Core performance in the Win 7 Task Manager playing full chords etc.. The load is spread very evenly amongst the odd numbered cores but perhaps as been mentioned it has to do with Hyperthreading.........

Here's a screenshot showing the results of playing a 6 note chord with all 8 Layers active, several at full Poly, some with max Unison, some with Supersaw, some with reverb, arp delay chorus etc. In other words pushed far beyond what you'd find in a normal patch. The thing that impresses me is that the CPU demand overall is only 14% even with this huge patch. I notice there is a little usage of core 2 but generally it's the odd cores that are getting the work. Not complaining just wanted to point it out.........

EDIT: Wow this is a significant improvement in performance...I'm really pushing it and the CPU is barely breaking a sweat...for the first time I can run 2 instances with multi layer patches...great update.

Thanks. Generally a BIG improvement.

I'm still able to hit up to 60% with some patches though. And that with nothing else loaded. I've sent in a Support Ticket.

Well, try to push it more

just for test. More polyphony on more layers. Try to check if you can go to higher overall CPU usage (about 70%) and still have only half of cores used. I'm curious...

I just tried the demo for the first time. I have a 3.8Gz i7 set for audio- I can run Diva in Devine and play big chords with unison etc, never had a problem, but the first few multi patches I tried with the D16 gave me crackles at 50% CPU (Tried Maschine and Live 9.1 64 bit, example patch 'CS80 Hymne')

Did you try what was suggested to me?

You need to enable multi-core support manually (if of course your CPU has more than one core):

Yes I selected multicore first, I have an Ivy Bridge i7 and it says I have 8 cores running.

LuSH has multicore turned off by default. Just to avoid problems if something could go wrong even before you tried to react. You have to turn it on if you want to use it.

Found a background task running (my bad) - CS80 multi patch still running at around 55% on lives CPU meter but no cackles. Sounds and Looks nice, but I just checked the price- A little 'one trick' compared to say Diva (which I have) so I think I will be passing....I have said that before and then still bought things...bloody plug in addiction...

I don't know if it's possible to push it that much farther....beside if the CPU isn't distributed to the even number cores by now it's not likely to do so if pushed further........

It's only "one trick" if you don't have many tricks......

For instance can DIVA have 8 Arps running at the same time ?

Having said that I do plan to buy DIVA at some point....I've enjoyed the demo versions in the past.

Same patch runs at around 11% here in Reaper which is near spot on to what the Task Manager meter shows. Some hosts have notoriously bad CPU Meters. For instance I believe FL Studio's meter still only shows the first core's activity. Never used Live so can't speak for it's meter.........

Your CPU is slightly more powerful than mine so something is definitely wrong........unless your Latency is near zero....

D16 updated LuSH-101 to version 1.1.1
