yea, it simply crashes Wavelab. my drivers and system are all rock stable, no problems with other software whatsoever.

What is your system config there, in particular CPU class, speed, and memory?

Probs in Nuendo2:

Quality 5 crashes N2.
Saving a project with PLPar4 and then reloading it crashes N2.
Saving a preset and reloading it and the sound is right but the interface shows weird values.

BTW, Nuendo2 is basically SX2 at the core.

I'm sitting here running Sonar 5 Pro, with 1 instance of PLParEQ4, and 2 instances of PLParEQ1, plus the Lexicon Pantheon, and a K-14 Meter plugin. Runs fine, even though the system shows about 66-75% loading. No crashing. So far it seems to work okay on Sonar 5 Pro, Tracktion 2, and Adobe Audition.

Hi David,

did you save a song and reloaded it successfully? Are your plugins running at quality 5?

Best wishes, FRitz

Everything seems okay so far...

Configuration here:

P III 3 GHz + 2 GB RAM
MOTO 2408mk3
ASIO drivers in T2, Sonar 5 Pro with 128 byte buffers at 44.1 kHz.

Adobe Audition does offline and audition processing of only 1 plugin at a time, using MME extensions to MOTU drivers.

Definitely not pushing Quality levels 4 or 5 for realtime. When I try that in T2 I get massive breakups at Quality 5, and bad breakups at Quality 4. Those two settings should be reserved for track bouncing and only needed for low frequency EQ.

I have been running the PLParEQ4 with all 4 bands at Quality 3 for realtime streaming.

Yes, repeatedly saved configs in both T2 and Sonar 5 and reloaded with no trouble here.

But, I'm not attempting Quality 5. Why tempt the Gods? Quality 4 and 5 are for track bouncing only, and really only needed below about 100 Hz.

Quality 4 implies a buffer size of 4096 at low sample rates (= 8192 samples at internal high SR), and Quality 5 = 8192 low SR samples (= 16384 samps at internal high SR).

Note: if you run traditional phase-warped filters at 88.2 or higher SR, then the system does not bother to block the data into chunks and your performance should be even better than when doing phase linear processing.

The very heaviest loading should occur at SR 44.1 and 48 kHz, with 48 showing the heaviest loading. Above 80 kHz SR, we no longer have to upsample/downsample, and so those high SR's are more efficient.

BTW... if the systems run out of memory and cannot satisfy a requested allocation, there are memory handler traps installed that will (A) write to a log text file on your top level C: directory, and (B) immediately exit the program.

All internal memory allocations occur on the user threads, with Mutex locking between the process() thread and the user level GUI threads.

I have not seen any memory allocation failures, but for some reason, grabing the max possible memory at startup seems to crash the ReWire DLL in T2. ???

So we stopped doing that and simply allocate as needed along the way. That stopped tickling the Rewire problem and everything seems to be working just fine now...

What can I say? I will give Cubase SL a try here (I have an old Version 1.06 sitting here).

Cubase SL 1.06 runs just fine with 2 instances of PLParEQ1 and one instance of PLParEQ4, all at the same time. (Quality 1 on all instances).

VST Performance is showing about 40-50% loading here. Only running one track of stereo mixdown through at 44.1 kHz.

the version i grabbed on saturday works best here. I have samp project saved with 5 eqs, quality 5 which I tweaked for hours without any problems. The rendering/bouncing doesn't work though

The later versions that suppose to have better memory handling run out of paged memory constantly and choke the system in quality 5.

dbmcclain · Post by **dbmcclain** » Tue Oct 25, 2005 8:45 pm

Okay we finally had a failure here... After saving the Cubase project with 3 instances it fails on reload, again tickling the Rewire DLL. I will hunt down the culprit here. I managed to break into the debugger and saw that it trapped somewhere in PLParEQ1. So I'll take it from here....

Thanks for the error reports so far.

Hmmm.. the change from Saturday is that we doubled the size of the buffers at all quality levels. So quality level 4 today is the same as quality level 5 on Saturday...

that explains bigger cpu hit. I thought I was imagining slightly better sound in q5 with later versions as well

Now, THIS sounds extremely interesting!! Mid/Side processing is a must for any mastering application and comes very handy in mixing as well!

Thank you very much again for this wonderful eq! If you need some internal betatesting on a bunch of computers and hosts then don't hesitate to ask. I've got an old p3 laptop, an Athlon XP based system and several P4's at school that I can test the plugins on.

Cheers!
