Hello Dietz,

Thanks for the reply. Unfortunately nothing helps. I have now tried a lot of possible combinations of the various settings and although clearly better than my original setup where I would have a digital crackle every 30 seconds the crackles are still not completely gone. I can play a sessions once, twice, .. without crackle and then bang all of a sudden the next time there will be a crackle. They are completely random and occur at no given fixed position nor do they always sounds exactly the same either. I have now tested this with 2 different sessions: in PT without MIR no problem, smooth as always, with MIR the occasional crackle. This is very disappointing, I had very much hoped to be able to go the MIR route because it really works very well and the audio results are very nice, alas it seems that for the time being it is not to be.

Best regards, Bob.

PS I should also point out that I did the sessions in two ways: one with VIPro instruments in VE + audio inputs from other tracks in PT and one with only the VIpro instruments in VE going through MIR. It makes no difference, both in the more involved setup and in the simple setup there will be an occasional crackle.

Looks we have the same problem with Logic

Hello Dietz,

Do you have any further ideas as to what may be causing the problems in my setup and how I might avoid the crackles. As I said before I really like MIR Pro very much and if possible I would like to be able to solve this problem. Thanks for all your help so far.

Best regards, Bob.

Hi Bob,

I was thinking about your problem, but as much as I tried, I can't figure out a good reason for that behaviour.

Are there any background activities going on that could interfere with the pretty high CPU demands of MIR Pro? Virus scans, firewalls, network activities, power saving options, or (a wild guess) MIDI SysEx transfers ...? There must be some well hidden conflict somewhere as soon as ProTools is part of the equation, because you wrote that MIR Pro behaves correctly when used stand-alone.

Kind regards,

PS: I was talking to Florian Walter (the driving force behind MIR's convolution engine). He kindly asks you to send the two simple test-setups you were describing above to , with something like "For Florian" in the subject line. He will look into it as soon as he finds the time. Please include all the information that is necessary to recreate your setup as closely as possible. The main difference will be that he uses PT 10 Native, not HD, though.

Best,

Hello

It looks that Protools user are having almost the same problems than with Logic

My buffer in Logic are set to 1024 and 0 in MIR

I made more test yesterday and it has improved

• I have remove the left window of VE (the horisontal faders) 
• I have also modify the setup of the buffer in Directory Manager

           raid 0 of  4 x ssd = 2048

           256 gb ssd = 3072

           If you do not have ssd leave it to default.

• You can also check that there are no old effects on VSL tracks in Protools

Tell me if has improved in Protools too ?

Dear Dietz,

I do have McAfee Virus scan which is standing on on-access scan. So that might be a problem. I also have the firewall of the mac on. Neither however give any problem with PT, and of course I have followed all the Avid directives to be followed so that PT runs without problems.

In the meantime my demo has expired. There is something strange with the demo. At a certain point when starting VE a warning window came up to say I had 25 restarts left and then because I had to force quit VE (clicking OK in the warning window does not make it go away and VE simply hangs) and restart it several times always because of this warning window the number of restarts went down to 5 without so much as having started anything. I would like to suggest that it might be worthwhile to consider changing this system. A time limit of say 14 days without limitation on the number of restarts would probably be more interesting and less cumbersome. I hope you do not find me presumptuous it is just an idea.

With best regards, Bob.

1. Virus software is always a bad idea on a DAW. I suggest you disable it whilst working on music, when you're not connected to the Internet.
2. firewalls can be on, as long as you have set them to "allow" VEP, which by the sounds of it, you have.
3. You can refresh the starts as many times as you need to, within the month, via the eLicenser software installed on your computer.

Thanks DG! I did not know that, I'll restart the trials then and do some more testing.

Virus scan is now off of course.

About firewall: I do not seem to be able to allow anything, it is just on or off. It does say that it will block all sharing services and all incoming connections except those required for basic internet services such as DHCP, Bonjour and IPSec.

Best regards, Bob.

Bob, just to keep you informed: Our support received your files and tested them, but up to now we couldn't reproduce the problem.

We will continue our tests, though .... sorry that I haven't better news for you before New Year's Day ...

Thanks a lot Dietz, it is much appreciated. My trial has now run out so I cannot do any further testing, but hope that I can maybe test a following update.

Best regards and happy new year.

Bob.

Did you run out of starts, or are the 30 days over already? You can "re-fill" your demo-starts as often as you want within those 30 days.

Actually I thought my time was really up now, but I checked and it seems time does after all not fly as fast as I thought, I still have a good week into the new year. Hence I'll restart again next week.

Best regards, Bob.
