Subject:Constant crashes with pan envelopes - Am I doing something wrong?

I'll be fine with 4.0 (even the non-a version), and then I'll insert a panning envelope in a track and the whole thing will freeze up on playback with this really annoying never-ending whine that makes me have to cold-boot my system.

This is my first attempt to use panning envelopes for some spot panning here and there, having until now just used the multifader pan slider. Am I doing something wrong? Does the track have to be mono to use a panning envelope? Does the multifader slider have to be set to zero first? Is there a trick here that I'm missing? HELP! I am SO sick of this mix!!!!

I've rendered out all my tracks (8) but one so I'm not running any effects except a volume envelope on two of them. One of the two is the one I want to use the panning envelope on. Do I have to get rid of the volume envelope first?

I guess nobody has an answer to this question?

I've just tried every possible way of adding pan envelopes, and have not been able to reproduce any of the problems you are describing.

Could you post a few more details?
Are you using ASIO or Wave drivers?
What is your 'Playback Buffering' under Options->Prefs->Audio set to?
Can you add the pan envelopes successfully while playback is stopped?
Are you adding them via 'P' shortcut key, via right-mouse context menu, or via main menu?

To answer your question about whether you're missing a step -- whether the pan fader needs to be visible, etc. No. You don't need the pan fader visible. You should be able to add a pan envelope to an audio track at any time.

Thanks for your patience, and hopefully we can figure this out soon.

Yes, I'll try. Though forgive me if some of this is mysterious to me.


Are you using ASIO or Wave drivers?

I've got Microsoft Sound Mapper loaded, with the Interpolate box checked in advanced but the pre-roll box unchecked. I've got the midi time code set to SB Live A and 30 fps, although I don't think I'm doing anything with midi time code (I'm in waves at this stage). I'm at 44,100 Hz sampling and 24 bit depth. I confess, I don't understand enough about these settings to know what's optimal for me.

I'm trying to find where there'd be something that says ASIO. In my Control Panel under Audio devices, I show Creative EMU10K1 Audio Processor (WDM), which is what installed when I updated my SB Live! drivers about a month ago. So I don't think I'm using an ASIO driver. There's a long list of soundcard drivers in C:/WINNT; is there a driver name I should look for?

Also, I bumped back my hardware acceleration from Full to the next lower notch and left Best sampling under Advanced Audio Properties in Control Panel. (XP)



What is your 'Playback Buffering' under Options->Prefs->Audio set to?

.35. Seems like I changed (lowered) this earlier and it caused less freezing in 4.0. But that was before I tried to do the pan envelopes. Should I set it at something else?

Also, I lowered my monitor refresh rate a hair (from 75 Hz to 72 Hz) to see if that would make a difference. I don't think it did.



Can you add the pan envelopes successfully while playback is stopped?


Seems so. I can add them, but then when I try to play them, either soloed or with the other tracks (not many), I get the never-ending whine freezeup thing. I get this even with no effects enabled. I should add, though, that my project length is almost nine minutes long. I don't have the Wave64 thing enabled...should I?



Are you adding them via 'P' shortcut key, via right-mouse context menu, or via main menu?

After I insert a panning envelope via the main menu, I left click on the pan line where I want a point, then right click/add point.



Hope this helps us figure this out! Thanks for being patient with me.

You should not uncheck the pre-roll. This was added for a very specific bug with one or two sound cards. This can cause all kinds of playback issues with the mapper or other Wave/WDM based drivers.

If you are not slaving ACID or generating MTC to another app, then disable this.

If you are using an SBLive or Audigy, then you might want to work at 48 kHz. This is the only sampling rate that these cards support internally. When you use 44.1 kHz sampling rate with these cards (or the Mapper) you are forcing Windows to resample on the fly. This can be expensive. Also, when recording, Windows will offset buffers internally causing recording and playback to be out of sync.

OH! Thanks so much for explaining this! I did everything you said, and I expect that's going to take care of a lot of problems. The most recent being a loud gunshot at the start of my rendered files! :) SERIOUSLY! :)

I have just one question: What does Acid do to a file that's downsampled from 48,000 to 44,100 Hz? I've been rendering to 24 bit, then applying very light dithering in Cool Edit on downsampling to 16 bit prior to burning to CD. I haven't tried this straight out of Acid because I have to do things to the wave in CE2K first anyway.

Will what comes out of a 48,000 Acid project rendered to 44,100 (either 24 bit or 16 bit) already be in good shape?
