Hardware required for Diva, what are you using?

[Howard]

With respect to the OP, the question of how many voices of the most cpu intensive patch a new system can handle has more relevance (it's unlikely that anyone will be thinking about buying a 4 year old machine to run Diva).

This isn't a contest - people who still use 2007/8 computers might like to participate and compare results. Then perhaps they will upgrade and use "divine" more

Precisely.

This could be a good measure to determine what one can expect through a computer upgrade with respect to DIVA.

Mine is from 2007 but was/is already a Quad Core (Core 2 Quad Q6600).
Based on that comparing CPUs from 2007 seems to be a valid point...

Which bit of my post said or even implied it was a contest?

For people *like myself* with vintage machines, how well a spanking new fast cpu handles Diva's expensive patches is of real interest. How other people's old machines perform is neither here nor there.

For you, OK. But for others it will be both "here and there" IMHO.
And... of course anyone can post any stats they like!

[Viktor [TUC]]

On an Intel Core i7 860 @ 2.80GHz here, test patch "INIT Alpha":

Divine: 5 voices
Great: 6 voices
Fast: 11 voices
Draft: all 16 (using about 60% of the one core it's running on)

I want an i7 toooooo!!!!!!!

99% of computer audio software owners are insecure.

Or, maybe they're not...

In 50% of all cases, the opposite of a fact is also true.

I've had no problems with i5-2500k overclocked to 4.4GHz.

Damn, is there smoke pouring out of that thing?

When I was overclocking (in my case an i7-2600K) I had my finger on the bottom of the heatsink.

While running an Intel Burn-in test at 4.8GHz, the CPU temperature got to 80 degrees C, but was still stable.

To my finger, the heatsink was warm, but no way was it hot.

I decided to keep things at 4.4 GHz to stay under 72 degrees C always.

If you go with the new liquid cooling fans you could probably reach 5 GHz and be stable - but there is a certain luck-of-the-draw in getting a magic CPU.

Your choice of memory will also make an impact on the overall performance.

And pump noise is different from fan noise - plus there may be some long-term issues with liquid cooling and some bad disaster scenarios. The thermal mass of the liquid coolers is small, so if the pump fails it will overheat easily.

Obligatory stat- 37.8% of KVRers would rather post than make music.

Here are my results

DAW: MacPro 2008 2 x Quadcore 2,8 GHz
Cubase 6.05, Project at 44,1 KHz and 24 Bit
Buffer Size: 256 samples

max. Notes playing same time (triggered from cubase) without crackling, using INIT Alpha with 16 Voices
draft: 16
fast: 12
great: 7
divine: 5

this isn't bad for a Mac build eary 2008, what do you think?

[xh3rv]

Oddly enough the number of voices I get is linked to how high the MIDI notes are, so I did C3 + the next n MIDI notes

2.4ghz Core2Duo MacBook, Live 8

Mode || Buffer [ 128 ] [ 256 ] [ 512+ ]

Draft: [ 16 ] [ 16 ] [ 16 ]
Fast: [ 9 ] [ 10 ] [ 10 ]
Great: [ 4 ] [ 6 ] [ 6 ]
Divine: [ 3 ] [ 3 ] [ 4 ]

IMO there really are sounds nothing else does well enough to sound 'right', and I figure that list in my head might expand with more CPU so seeing results is really informative. Definitely don't find Diva unusable though.
