DP9.01 and optimization

sdfalk · Post by **sdfalk** » Sat Oct 31, 2015 1:03 pm

Hey guys;

I've not posted in quite some time, so hey hey everybody.
I'm having major issues with DP9.01, Yosemite and CPU overloads.
I'm running a garbage Can Mac with 16gb of ram, and done every bit of
tweaking I can think of to get DP to run efficiently.
So far, no dice.
CPU overloads with small 10 track sessions with minimum plugin counts.
I've (I believe) properly configured the audio settings.
Work Quanta, Prime seconds, and Max work percent, have been adjusted and
readjusted a lot.
My interface is an SPL Crimson.
I've also tried using DP with just the built in audio, and still these problems
persist.
I've tried a different Daw, and can run it at much lower buffer settings, with
vastly more efficient results.
So I'm fairly certain there's nothing wrong with the computer.
No, I'm not mentioning the other Daw..I've seen enough DP vs... and I'm not
interested in starting that discussion all over again.
DP is what I'd rather work in..
Any help..as always would be greatly appreciated.

Welcome back!

Are you getting actual audio dropouts or other issues, or is this just based on DP's overload meter (or warning screen if you have that turned on in prefs)?
Have you looked at Activity Monitor to see if anything jumps out?

Thanks for the welcome.

Definite audio Dropouts (in conjunction with DP's meter overloading)
Nothing jumping out on The Activity monitor..I'm only running DP, and
nothing in addition in the background.
All other background processes appear to be running normally.
I run a fairly lean ship.

At the risk of being overly simplistic, have you checked for the latest drivers and ran the usual permission repairs on the system? That was essential in DP8. The MOTU Audio System can be especially "buggy" unless you repair permissions (which I suspect you have).

I'm using DP9.01 on a MP trash can (2013) with 32GB/RAM and have zero CPU issues, whether I'm using the Track 16 or built-in audio.

Not at all..

Thats a very good point, permissions.
I'll have a run at that when I get home tonight.
As for the drivers, Ive been using core audio with the Crimson.
It does have drivers if I want to do 192khz, but those drivers have been
a "bit" problematic.
I'll see how the permissions repairs goes when I get in tonight.

thanks everyone

What build of Yosemite? Is this happening during tracking or playback or both? What buffer settings are you using?

10.10.5
Buffer settings are any.
Meaning as low as 128 and as high As 512
tracking and playback
If another daw is capable at buffers as low as 32,
DP should be able to at least get close I should think .
Keeping in mind I haven't gotten any lower then 128.
Also as I said , 10 tracks, not many fx , 24 bit 48khz

I had the same problem initially. I see you adjusted the background settings but max work percent was the setting that fixed it for me. I left everything else the same and lowered (!) it by 10% and all was well.

How does it behave when you load a blank session? And then start adding in tracks and then plugins.

What plugins are you using?

If another daw is capable at buffers as low as 32,..

Yea, that doesn't matter. Not one bit.

What happens if you increase the playback buffer?

When I increase the playback buffer as high as 1024 it smooths out a bit, but still with intermittent (though not as often crackles/pops) as for it not mattering..I'm afraid we'll have to agree to disagree.
I'd prefer to work in DP, but I'm getting larger track counts with more fx processing in another daw. I'm just trying to understand why one works well, and the other doesn't work as well..

Repairing permissions appeared to help a bit, it's lessened the CPU overloads/clicks/pops...I might just try a complete reinstall at some point soon..once I'm finished a project..thanks MLC

De nada!

Have you submitted a Tech Link to MOTU?.

I'm not saying there isn't a problem. Look at the setup in my signature - your Mac can run circles around mine. I'm running 50+ tracks with plenty of CPU hogging effects with no problem. A 512 buffer doesn't work for me unless the track count is around 6.

You can agree to disagree all you want. To me, it's the same as wondering what's wrong with Office when Text uses far fewer resources. It's not an issue

I can run significant projects with lots of tracks, plugins and VIs at 128 buffer for tracking, no audible artifacts, but DP's meter will peak occasionally. cMP hex, as per signature.

Yes

I've submitted a tech link to Motu ...i saw your signature , and I'm well aware of what the computer should be capable of ..I'm running 90 tracks with a boat load of plugins on my "other" text editor /word
Processor/daw... And that's good for me .. I'll wait to hear back from Motu..

Edit:
I will add a couple of final points;
I'm really concerned there's an issue with my hardware (i.e. my computer/interface/drives)
and I "thought" one way to troubleshoot (aside from everything else I tried/was recommended
to me) was to run Two daws with the same sessions, and similar plugin setups.
As a sequencer reads a disk, when playing audio and accesses CPU resources, when using plugins, I
"thought" (silly me) this might be one way to try and troubleshoot my issues. Apparently not
