multiple instances of DP

[Randy Hale]

I've tried with some success to get two instances of DP4.52 to run together. If anyone is doing this sort of thing, I'd appreciate a heads up. I've got it working, but not in sync.

thanks

studio:
g5 dual 2.5, 8gig ram, multiple vi's, waves, hd192 (2). nothing else running.

You have a g5 dual 2.5, 8gig ram, and apparently need to have two DP's running...

To quote my goood frieend Tony Montana,

THE WORLD IS YOURS

I have a dual G5..believe me, with DP, the damn thing still gets slow..as much as I love DP, it cannot compete with pro tools which has it;s own comp. The moment one shackles his balls to the MAC OS...things start to suck....Thank you for listening...lol

[Randy Hale]

Yes, I was hoping the world might be mine - however, compeletly ramped up, with six vi's going, east/west gold with 18 instruments - dp is using only 3gigs max. I spoke with rhys at east/west, and he said the software is not built to use more two or three gigs, in fact, he said no software is built to use the full eight gigs - i guess it's a shill game - so unless i can opens several instances of dp - apparantly the ram is useless.

dual 2.5 g5, 8gig ram, vi's, waves, motu 192's, etc

toodamnhip,

What's your overall performance like with DP on the G5? Within the next several months, I'm looking at a fairly big 5.1 music project, which I plan to run on the fastest (at that time) G5 with roughly 2 gig's of RAM. I've ran some pretty large 5.1 sessions in Pro Tools and I'm wondering how it compares in DP. Your largest DP project? Thanks.

I would appreciate anyone else's input concerning performance and track count on any system, particularly surround projects on a G5. Cheers.

TRUE..Pro Tool TDM runs on its own native proceesor...dearer than a G5

With 15k spin Cheetah 320 drives and an ATTO UL4s scsi card, I get about 55-60 tracks safely at 96K and a few VI's.

This is all on one drive and reasonably reliable although I'm at cpu limits because of my plug usage.

I'm sure I could get more tracks if I had no autotunes and/or dynamics plugs but unsure just how many.

system specs below.

Hope this helps

For those of you who haven't heard, Logic users have been doing this multiple-instance thing for 6 months now. You use the second and third instances as sound modules (to get around the Apple RAM limit). Until the apps get on the 64-bit bandwagon, no app can access more than 3GB.

You can hook up with free-standing instances of Kompakt, or whatever else, as well. One must use the freeware MIDI Patchbay or possibly IAC within DP. If it's plugins that aren't stand-alone, you open the other DP's as a host for the plugins.

You must make a copy of DP and call it DP2 or whatever and name the MIDI ins and outs accordingly.

I didn't hear about that, but with the new Logic 7 you can add multiple computers and run a distributed computing audio cluster. I'd like to see DP add that as well...

[willtompkins]

Timeline,

I'm guess you could get that track count to at least double at 48khz, which would be adequate for me. I'm looking into a very similar setup (ATTO UL4S or D with 10k or 15k Cheetah), if you don't mind, about how much did you pay for that setup? Thanks.

HI,

One 320 72 GB was $400
One 320 36 GB was $300
ATTO Card was $400 but I don't remember for sure.
Bought cables,auto terminator and a 'two drive case' was around $150

Think thats about it.

How does one make the play controles lock together running two DP applications at once, or do you need two MTPAV units?

[Randy Hale]

that's just what i'm trying to figure out - was hoping someone out there had done it - how to lock the two dp's. has anybody out there done it?

By the way, what is a "distributed computing audio cluster"

thanks

The beauty of multiple instances of DP is that you don't NEED another computer!

My friend that uses Logic has an orchestral template that by way of 2 instances of Logic w/ EXS24 and a free-standing Kontakt accesses 12GB of RAM at once. He has 7 GB installed and the rest is is OS X's virtual memory.

Any comments from MOTU Tech Support on this?

Thanks!

I have heard of some taking two machines and locking them up and this seems like an interesting solution for multiple 96K audio tracks and lots of VI's.

Could someone explain how they would expect to benefit by running two DP's on the same machine. I can't see any advantage.


I have DP on two drives. One is 4.51 & one is 4.52.

I was able to open them both up and switch back and forth.

What I don't know is how the two DP versions would connect to the IO's via ONE 422 card.

I can imagine a situation for MIDI users where one is MIDI and one audio but I think two MIDI interfaces would have to be configured to lock the second system via the MIDI interface and timecode.

I agree with whoever said "the CPU will experience the same load although more ram might be accessed". The ram is not a big a deal here I don't think. It's CPU load and disk access.

For either MIDI/VI's and audio these will only improve with a second machine and separate CPU's.

Interesting though. Thanks for posting it.
