Hi all,

I posted all KNOWN reasons, why clicks and pops might occur on Mac, regarding unknown problems I already said:

we are also investigating in order to find a solution

However this might take a while since the problems occur randomly.

Best,

Here is a word for those who have suffered from this problem with hopes that you will find relief as I did from JWL. Also I learned from my precious wife that any firewire device has to share the same built in firewire controller. Lesson-Only use one firewire device if it requires a large bandwidth. I am a very happy guy now.

Dear JWL:

We thank you for a suggestion that made sense. I did not know that because I had the Fireface 800 connected to the FW 400 port and the Rocstor HD with the VSL SE library connected to the FW 800 port that they shared the same bus and obviously VSL does not like to share. When I hooked the Rocstor up to the USB port and left the Fireface 800 alone on the FW 400 port, end of pops, and end of sound dropouts. Now I am kickin it. Many, many thanks. [:D] [[:|]] [H] [[;)]]

Power Mac dual 2.5 ghz with 4.5 gb RAM Rocstor ext HD USB port with VSL SE library and Fireface 800 on FW 400 port

Is that a USB 2 port for you external hard drive???

Tim

Yes. I also intend to look into buying a PCIx card for any other firewire devices I might need to use. I need to research this some with regards to compatibility with the Fireface. The USB 2.0 on the front of my Mac seems to work just fine.

just as a sidenote ... VSL as such does not care about the method you connect what and where ... it is the file access handled by the operating system which is affected, VSL *only* is requesting a huge amount of data most of the time.

doing some research regarding firewire 800 extension cards is a very good idea - there are some really crappy products on the market. unfortunately i could only find the german page explaining what some vendors have done ... http://www.rme-audio.de/techinfo/fw800alarm.htm

I don't use any firewire harddrives. I use two WD 500 GB RE2 SATA drives internally for sample playback.

Another reason, why dropouts can happen is that Logic´s audio engine goes to a form of "sleep mode" sometimes. The result is that sample streaming from HDD doesn´t work anymore and only sample data which is already buffered in RAM will be played back properly.
In this case it helps to go into play mode in Logic and to play all tracks with Vienna Instruments instances for a few seconds. This will "restart" Logic´s audio engine.

Can the Logic audio engine sleep mode be disabled while working or does this have disadvantages? [*-)]:

Good Morning, Simon. I have felt your pain. I am curious and you may have said this in previous posts - Does your problem persist with the use of built in audio? My problem was timed with the use of the FW 800 port-ie that was the act that caused my problem. Did you attach anything new when you loaded VSL SE? If built in audio works, then it would seem to point to how info is handled internally with more than one HDD. Resolution of this issue is important to all of us as I am contemplating a new system.

Hello.

I still haven't tried with built in audio, since I don't have that connected to anything, but I will test it with a MOTU PCIe solution soon and see if that changes anything.

And no, I haven't attached anything special. And it's not VSL SE, it's every VSL instrument that behaves like this. It is related to the VSL engine in some way. Maybe the engine needs to be coded in a slightly different way to work 100% on OS X - I don't know, but Native Instruments and others got it right.

I'm with Simon in thinking "I give up"

You guys are worse than the Bush administration when it comes to aknowledging problems!

This is really too bad since all that we're asking is that you:

A. Admit that there "might" be something wrong with your app.

B. Look into it beyond just testing it on your office machine.

I'm running Logic Pro 7.2.3 on a Mac Dual 2ghz G5 with 4.5 gigs of thoroughly tested RAM and a 500gig internal SATA drive only devoted to sample playback. My OS is 10.4.9 and I'm using a Digidesign Digi002 with a Digocore Drive 7.1 My only other plugins are NI stuff, Stylus and the built in Logic instruments.

If you guys can configure a machine which has my same specs and you're not getting any clicks or pops when you use VSL VI, then I'll stand corrected that this is a VSL issue....but until then you have to at least admit that there could be an issue on your end!

Oh....and to answer Christopher's statement that I don't know how complex VSL VI instruments are compared to other sample libraries....hmmm...let's see. I load up 1 instance of VSL SE soloAlto Flute legato and I get clicks and pops.....I load up 20 instances of EXS24 playing orchestral string sections with auto alternation, release samples and mod wheel crossfade and no clicks or pops. I load up a dozen Kontakt 2 instruments from QLSO with the SIPS Kontakt script for legato playing and I also don't get any clicks and pops. Even Sonivox Flying Hand percussion which has 400 meg instruments with tons of velocity layers and round robin alternation doesn't give me issues. True I don't have an side by side comparison of VSL VI vs. VSL....but come on!

One last thing....FYI, turning off the Release Samples will sometime get rid of the clicks and pops....could the release samples be causing these problems?

I see two clues in your post, Kays. First, if turning off the release samples gets rid of the noises, either you're getting data corruption somewhere or the number of voices is pushing the system over the top. That doesn't mean it *should* be doing that, just that it is.

Second, Digidesign's Core Audio drivers have been known to be...[slumps as Digidesign rep hits him over the head with a frying pan]

Nick,

The issue here is not whether or not I'm pushing the system over the limit (I'm not), it's why this happens ONLY with VSL VI.

With all due respect Nick....neither Simon nor myself are amateurs, we started using this technology while most people were still using hardware samplers (and virtual instruments didn't even have a name...let alone a magazine), and I think I can speak for Simon when I say that we've both have had to develop our troubleshooting skills the hard way (ie. not by posting on a forum to get a quick answer).

Give me a call and come by my place....I'll show you what I'm talking about....you can sit at my system and futz with it until your satisfied that this is a VSL VI issue.

Also (to clarify) the turning off the release samples thing only works sporadically, so I'm not quite sure it's related to the issue at hand.

I know you and Simon know your onions, Kays, I'm just trying to help figuire this out. Or maybe there's a way around this to stop it from happening.

As you say, the question is why the V.I. Player is crackling on your systems when other things aren't. And why is it not crackling on mine, at least not until I push it hard?

You and Simon are convinced that it's simply because of code in the player. I can't say that's not so, but the fact that it's not crackling prematurely on my system makes me think there's something else going on - and what I think is going on is that it's pushing your system harder than the other instruments are. Crackling is a symptom of many problems, of course, so it's also not guaranteed that you and Simon have the same one.

I'm not trying to be patronizing, but as much as I like Pro Tools, writing Core Audio drivers may not be Digidesign's highest priority. That may cause problems when you push the system.

Or maybe I'm wrong - the player is totally messed up, and both cm and Maya are stonewalling so they can get jobs in the Bush administration.

it is starting to get ridiculuos and boring to read arguments like *why is my helicopter much louder than my bicycle - there must be some construction failure with my helicopter* ..

besides that i can tell you, i'm taking the comment regarding a certain administraion as personal insult - not joking.

i am working with computers and various programs and operating systems since 1973, including but not limited to the early BSD (which is commonly known as predecessor of OS X) - so you can assume i'm understanding at least *something* from the stuff i'm talking about.

the usual procedure to track down an issue would be to remove all unneccessary components until you have a basic, clean and working system - then adding one piece after the other in various well considered sequences to find out when and for which combination the problem (and which problem exactly) arises to find the reason, not the effect.

the way you are re-iterating your rants is not only damaging the reputation of VSL but - with all respect - beginning to impair yours.

we are not saying the Vienna Instruments Player is perfect or cannot be improved, but it is definately impossible that a single instance with a single patch shows the described behavior if everything else is fine.

so either we are returning to the starting point and try to find the culprit in a cooperative manner or you continue to fill this forum with rants without taking notice of our suggestions and considerations.

our support can only be of any help if someone allows such a help.

Christian,

First of all, these "rants" as you call them are actually quite calmly typed as a response to you guys that keep on essentially saying "It's OS X's fault, our player is perfect".

If VSL Player needs a substantial amount of processing to operate correctly, then I wish that I would have had that information before purchasing it.

In the spirit of co-operation, you start by giving me an inkling that you actually are concerned and I'll stop comparing you to Mr. George W. sound fair?

Nick, I was totally serious about you coming by my place. You got my number, and you live 20 minutes away....swing by, I'll show you what I'm talking about....then perhaps since you probably have more clout as a magazine editor than I do, you can help me get someone to listen.

Thanks guys...let's keep it friendly....don't read your own tone into what I type, people who know me personally know that I'm a friendly guy.

If you worked for me, and you did that, you definitely would be up for review. Bringing emotions to a professional environment is completely unnacceptable. Maybe that's ok in Europe, I don't know enough about European professionalism, but in the USA it's considered bad business and even opens you up to litigation to bring emotions to a corporation's public relations.

It's the same cycle as before, this thread. Someone stood up and said that how you conducted yourself was not standard, and you responded by feeding the emotion of the customer with further emotion.

When will there be diplomacy and professionalism with regards to these matters? Will it ever change at VSL?

Evan Evans

Thanks Evan, I appreciate someone else adding their feedback to this.

Christian,

If you could IM me perhaps we could try and figure this thing out as you could ask me some specific questions and see if we can get to the bottom of this issue.

As an added factor....I do everything at 48khz...could this be contributing to things? Could you guys run some tests with sessions running at 48khz and see what happens?

No problem, midphase, but I do wish there was a nice way to say these things sometimes. There probably is a way, but I am not so good at it. Sorry cm/vsl if I can't seem to be real friendly about my criticisms.

Evan Evans
