Diva Vs. Real Analog

[projectdan]

But if you look at the 32 buffer test there's an OCd 2600 that runs 261 plugins compared to the 54 of the non OCd 6700. Maybe that's what i remember though that isn't a fair fight. Ah well Moores law will make me right soon anyways. Just wait for the Ivy Bridge.

I have seen similar benchmarks based on actual plugin use. Sandy Bridge does have new instructions, maybe its dependent on the use of these?

Damn, don't where i got that info from. I remember reading it and was all like Wow the 2600 is 5 times as fast as a Q6600 which i still think is a decent CPU.

Regarding HT: well yeah and maybe no. That subject gets a really complex really fast. You do have a point there.

It's very important to compare which plugins can be run x-times on each CPU. This can differ greatly with different CPUs. While it's a rough indicator of what's going on I don't draw too fine conclusions from seeing how many instances of a certain compressor can be run on both CPUs. The numbers can be very different with another plugin.

perhaps, but at the moment, more cores does not help run a single instance of a soft synth...

True of DIVA at the moment but not true in general. To the degree that a synth implementer can introduce multi-threading into the processing, multiple cores can indeed make a consequential improvement in how much sound can be delievered by a single instance, be it more consecutive notes sounding or higher levels of rendering quality.

Urs has stated on the u-he forum that his initial attempts at getting multi-threading into DIVA didn't meet with much success. Don't assume that some inspired breakthrough won't happen for a future release of DIVA, however.

The problem with Multicore support is that I always optimised the memory usage of my synths for sequential crunching of voices, and the modules within the voices. This works well as long as instruction memory is small and audio memory is considerably large (Zebra's voices for instance render into 14 buffers, due to the modular approach).

DIVA however is strictly mono (small audio buffers) and has an excessive level of instruction memory. This actually favours per-module rendering, voice after voice. Like when one type of module is finished for all voices, render the next module for each voice.

Thus dividing cores by voices as we did is, uhm, suboptimal for DIVA (while probably great for Zebra). Hence we're investigating ways to restructure the voice scheduler into a different approach, which we think will scale very well across 2 or 3 cores for DIVA. As in, one core does VCOs, one does HPFs and another one does LPFs/VCAs. Something like that.

While we're on the topic of Moores law, we're also looking into deploying the AVX instruction set of Sandy Bridge processors. This stuff can give our filters maybe a 30% performance boost.

We'll see...

At the risk of having the mute button pressed...

Initially I wasn't sure why I should get Diva as I already own ACE (and DCAM Synth Squad). Then I loaded some Diva basses and cranked up my Adams. Boy, now I know that my room needs accoustic treatment!
What I miss though with Diva and ACE - flamesuit on for purists' attacks - is a good arp! This also with regards to upcoming soundsets!

Might happen. We were reluctant to adding arps and/or sequencers because we want to first tackle multicore support and the possible repercussions that come with it. Arps can make this really complicated, depending on what changes have to be done.

That would be great! I also think there is an opportunity to do things different regarding arps !

It would be great to see a proper chord arp in DIVA , something like the one from the Supernova 2 synth . And a sequencer......pretty please.

Check out HGSounds Arp, step sequencer, loads of different arp modes, scales and chord mode. I use it with everything.

[Gonga]

That's an interesting recommendation, and I like your siggie

Could Diva be programed to run on CUDA cores haveing the graphics card help out would be a huge boost to computing but I'm not an expert. Just wondering about the posiblity of it. My i7 3.5 ghz with multithreading turned off already handles Diva pads in Divine mode at 48khz without a problem.

Is there a similar app for Mac?

Well maybe not as good, but free.

There is also 2 good one's, each about $100usd here.
Thesys

and XX5
http://uisoftware.com/XX/

I have all these, and I love Thesys, but haven't done enough with it.
The XX5 is amazing, if it wasn't so buggy.
Neither of those is an arp though, but can do arp type patterns, as sequences.
I would say try the XX5 demo out, and if you have problems, then just select in options, not to load AU's, then you can just export the midi and do it up in your daw instead. It has great pattern creation tools.
For just the arp thing, the Kirnu is a step above most.

Thanks. It's a cool little plugin and the dev is really responsive to FRs and updates.
