V-Rack question

[dpg4macman]

I decided to try using a v-rack for the first time and loaded it with five VI's. (ST2,MX4x2,Independence & Rhino)I am running 32 bit and noticed my memory meter glowing bright RED. With only two MIDI tracks recorded. Is this normal? I have noticed DP8 using more memory than DP6. I also tried this in 64 bit and was still having memory issues. I have a Mac i5 2.5GHz with 16g ram installed. I would think I shouldn't be having any memory issues. Is there a preference I need to set?

Any help appreciated,

If the meter you are looking at is the one that exists in DP, compare it to the one in Activity Monitor, and rely on that instead. It's not clear what the DP meters are telling us.

Other thoughts: I usually put each VI in a separate V-Rack so I can turn them on and off in the Chunks window to minimize CPU load. Also, have a look at Magic Dave's suggestion to run multiple instances of VIs rather than multiple MIDI tracks on a single VI. This distributes processing across the processor cores.

And, there's something about repairing permissions before using in DP 8 ...

If that's a multicore machine, put each VI instrument in it's own V-Rack. MagicDave says that distributes the load among the cores (or in separate tracks if you;re not using VIs).

The repair permission thing was (I think) when you update to DP 8.01. It repairs many audio things.

Thanks guys, I did pull out the activity monitor and have my cpu meters displayed. (4 processors - 2 cores) According to the activity monitor and menu meters I am only using 5 to 6g of the 16g memory so I suppose the DP meter is showing a false reading? I have better luck when I create a VI in it's own track vs. V-rack. The only instrument I use more than one instrument in for one instance is SampleTank 2 and I never have an issue with it. (That is unless I try 64 bit - gave that up - I wasn't seeing any benefit far as memory was concerned so I switched back to 32 bit)

Thanks again,

I turned off the "Audio Performance" function in control panel preferences. The big RED line for memory was driving me crazy. I'm not having any performance issues.

Just a point of clarification I hope: A single V-rack may contain one or many strips. Magicd’s advice is to run one VI instrument per strip, not necessarily one VI instrument per V-rack.

His response to me (on this board) seemed to indicate that it is essentially a 'per fader' issue. I understood it to mean one core for each fader so that would mean one VI per Vrack. I've not had time to evaluate that empirically.

Agreed.

Agreed.

so that would mean one VI per Vrack.

I'm open to correction, but I don't follow here. As a single Vrack may contain one or more faders--like the Mixer--if a single Vrack has, say, four faders then each fader would address a separate core, no?

From what I understand the memory meter is showing how much of DP's available memory is used. In 32 bit mode DP can't access most of your mac's memory. Any 32 bit app can only access 4 gig of memory. The v-rack has nothing to do with your problem. You just loaded too much stuff into your synths for 32 bit mode. When I got DP 8 I switched everything to 64 bit and I'm never going back.

One core per fader. Many faders per V-Rack. Many cores per V-Rack.

Thanks for the clarification guys.

All is right with the world.
