I know this forum is dead but I\'ll try my luck;

Can any body update on Kontakt\'s bugy dfd situation?

[Rich Pell]

For PC or Mac?

[Chaim Goldman]

MAC AU in DP4

[Rich Pell]

Chaim,I think NI are realizing how buggy some of there MaC plugs are and are working on this for the next update. Like. I`ve heard that there optimizing Kontakt and Kompakt for G5 ,OSX so that 3.5 GB of ram can be recognized(as apposed to 2 GB in XP)..Hope this helps its all ive heard images/icons/wink.gif ..Rich

[Chaim Goldman]

I can access right now more than 3.5 GB of RAM in Kontakt. What I need is a working dfd.

For me Kontakt works just fine on the mac G5 and DP besides dfd. (and multi outs, but that\'s not a Kontakt issue, it\'s an AU/DP thing)

Chaim, Have u tried turning off your Page filing(virtual memory)? With that much ram ,OSX should need it. And on expert settings~ 192 pre-load buffer around 194 and voice buffer around 300 with 250 reseved voices..On my PC`s, this has worked wonders for me...Rich

[Nick Batzdorf]

Chaim, I think you\'re seeing more than one thread\'s memory usage being shown. The sequencer and any soft sampler both fit in the same 2GB thread.

The people who told me that are very reliable, so I\'m inclined to believe them.

Nick,

If I can load (and I can) a 2.3 GIG piano entirely in RAM (no streaming), what does that say?

Where exactly do I turn on or off Page Filing?

The dfd bug I\'m talking about isn\'t that I have poor performance or processor peaks. It\'s when I release a note, the end of the sample replays. This is a known bug on the mac.

If I can load (and I can) a 2.3 GIG piano entirely in RAM (no streaming), what does that say? <font size=\"2\" face=\"Verdana, Arial\">It says that either:

1. you\'re not really loading 2.3GB in RAM (one avenue to check: space on disk is larger than the actual file because everything gets \"rounded up\" to the next HD block);

2. Clemens Homburg, who programmed the EXS24 and explained this to me three weeks ago, is completely full of booshwoogie;

3. CM on the VSL forum (and occasionally here) has no idea what he\'s talking about;

4. NI has actually found a way around the 2GB per thread limitation, even though by all accounts AU plug-ins must be in the same thread as the host sequencer and it doesn\'t make any sense that they could possibly do that since they\'re not programming the sequencer;

or I could speculate that

5. NI has figured out a way to make something like a RAM disk, which would only solve our problems if RAM disks could be 300GB or so.

#1 seems by far the most likely to me. I really want to believe that you can load much more into RAM - in which case I\'ll buy a G5 today - but alack. And of course I want a 1-machine solution as much as we all do!

So I would be very happy if someone could prove me wrong!

[Rich Pell]

Also ,I have alot of the big piano sample libs. and i dont know of a SINGLE patch thats 2.3GB large. But perhaps 3 diff. mic perspective could make up 2.3GB. Chaim, Im not sure where the page filing in Mac is but on a PC in in My Computer/Properties/Advanced/Advanced/Peformance/Virtual Memory. Having your VM (page filing) on is in conflict with Kontakts DFD. But perhaps your Mac problem is a diff. story. Ni are always the last to get there #%!% together on Macs. images/icons/rolleyes.gif Peace, Rich

[Chaim Goldman]

Rich,

It\'s the Bardstown Bosendorfer, wich Nick, your\'e right it\'s not 2.3 gigs as I said, It\'s 2.26 gigs. And even if that\'s rounded off isn\'t it still more than 2 gigs?

I opened Kontakt in DP and loaded the 2.26 gig piano + a 203 MB patch + a 278 MB + a 57 MB patch all in RAM.

Now what? Is that more than 2 gigs Nick?

It could be an EXS limitation now. But from the G5 itself it\'s possible to access 4 gigs per thread.

[Nick Batzdorf]

Interesting, Chaim.

Unfortunately, I don\'t have a G5 to test this (nor the OS X version of DP at the moment), so I\'m only going by what I\'ve been told. I still sort of think it\'s unlikely that both CM and CH would be wrong about this, but it would be great if they were.

I\'m going to get to the bottom of this. Maybe it\'s different in DP.

[Chaim Goldman]

Some one posted a link to Apple\'s website a while ago where it says clearly that one thread can access 4 gigs of RAM. I saw it then, but can\'t find it now.

[Nick Batzdorf]

Okay, Chaim, here\'s the story (thanks to CM).

You are indeed loading more than 2GB. But you don\'t have streaming turned on! The problem is that as soon as you start loading more programs than you have RAM for, the OS starts using virtual memory on the hard disk - the Swapfile - at which point you won\'t be able to play anything.

So there are two different memory schemes at play: the OS X scheme, which works fine if you don\'t load too much into RAM, and the soft sampler\'s proprietary disk-streaming scheme, which is limited to 2GB (minus whatever the host sequencer needs). BUT: that 2GB is made up of sample starts, not the entire programs, and of course that gets you a whole lot more mileage.

The other issue is whether you\'re actually playing this piano with lots of voices, not just loading it. I suspect you are?

So you\'re absolutely right. But unfortunately you\'re not as right as we all wish you were.
