Written audio missing.........

Sometimes on PA 9.03, the written audio in the track view will disappear for a few of my tracks. The tracks still play but it just looks like nothing is there. This happened to me awhile ago and I had reinstalled Cakewalk after formatting my hard drive and it just started to do it again. I don't know if this has ever happened to anyone. If ya can help..thanks......Josh
 
Are you talking about the "pictures" of the wave files?

If so, just give it some time and it will reappear. Cakewalk keeps these pictures in a cache. Once the cache gets full (or if you delete it, such as by reformatting your hard drive) the program needs to redraw the waves. Soemtimes this will take awhile.

You can reduce the need for redraws by making the cache larger (if you have room on your hard drive). Go into the Aud.ini file and change the setting for PicCacheMB=XX

I think the default is 20 Mb. Set it for 50 or 100 if you have the room, and it will keep more of the pictures in the cache.

However, it's nothing to be concerned about. As I said earlier, just give it a little time and the pictures will reappear.
 
I haven't had the chance to try and change that but it's something where after cakewalk writes the pic, it goes away after awhile. I'm not sure if it's the same thing you are talking about. At one point I can see it and then after time i can't. And if i save it as a bun or wrk file and reopen it it's still missing. But i will try your suggestion.......Thanks.........Josh
 
there could be two other explanations for that happening -
1) you're not 'picking' the tracks you want to see, there's a button with two arrows in the audio view's task bar where you get to choose which tracks you want displayed in the audio view; 2) you're recording multiple takes in a single track, and sometimes the one take you're listening to is under another one played over the first, and which has no sound playing during that part. you can either slide the upper one to another track or edit the silence out so you can see the other track underneath.
but maybe it's none of that, and i'm just embarassing myself (it happens a lot). ;)

To add to the confusion I have had similar problems with sonar where for whatever reason parts of old tracks disappear. No filled in spaces like the cache needs to refresh or an audio drawing, just empty space. It still plays normal but it looks very scary.???
 
This last problem in SONAR has to do with the slip editing. I discovered that if you take an audio or midi clip and cut it, then past that piece somewhere and you have not set the paste options to overwrite what's already there or slide over to make room, the audio that's to the right might seem to disappear, becuase with slip editing, the audio you snipped off is really still there, and I think there must be some ambiguity about how to display the new state after your paste. (Your pasted clip is not showing part of what's really there, and that state is masking what's underneath there.

You can cause the splits and cuts to be permanent by using the Edit -> Apply Trimming command...

It would be nice if they let you overrride the slip editing globally, as I rarely use it and I'd rather not deal with remembering how to avoid the masking or apparent masking of audio I expect to see there...
 
AlChuck - you shouldn't discard slip editing. It's a very powerful tool, and the nondestructive nature is great (particularly for someone like me who can never make up his mind about something). It gives you a lot of power in editing your stuff.

That's an interesting point you brought up, though. I have noticed that sometimes that when I slide a clip in time (using the edit -> slide function) the .wav picture immediately to the right of the clip I'm working with will disappear. It scared the bejesus out of me when it happened, and I immediately went to the undo function to undo the slide and the picture returned. I never bothered to try and "play" the clip to see if the audio was still there. Just assumed when the .wav picture disappeared, that so did the audio. Now you've got me wondering.
 
i don't use slip-editing for the same reason. as powerful as it is, it does me no good if i can't see it.

having said that i love the crossfade feature.

btw, i had the same trouble with the audio and i increased the picture cache setting (PicCacheMB=XX) and that worked great. I also have 640mb of ram, and 80gb of HD.
 
dachay2tnr,

Oh, I think slip editing is great when you want to do that... but it would be nice to have it off and then enable it when I want to...

I think the observation you made, about the audio to the right sometimes disappearing, is because it happens when you have a clip that has been slip-edited at the right side and the hidden data, if it were showing, would overlap the stuff on the right. So if you paste it without overwriting, it has precedence -- it's on top of the heap, so to speak -- and so it's masked-off, slip edited part covers up what was there before. I thought it was just random until I finally noticed this the other night. Maybe I'll test it a bit to see if my theory is correct.
 
I have just recently experienced the same problem as Maddrummer. I recorded 7 audio tracks (no midi) at the same time into a new project, but when I look at them in tracks view, some audio pictures are missing and others are present. I tried wiping out my picture cache to let Cakewalk redraw them, but it redrew them the same (i.e. with some missing). This is more than just minor quirk since I also can't see the tracks in audio view, making it pretty tough to draw volume envelopes.

An additional weirdness is that if I use the "increase audio 3 db" feature, or the "decrease" one, the picture instantaneously appears! I can actually do an increase, followed by a decrease, and the picture is still there. But, if I run an increase or decrease db, then hit undo, the picture is wiped out again.

I've tried copying and pasting all the tracks into a new project, and the same tracks are either drawn or blank. I can see that my picture cache is only contains around 7 meg of WOV files, with a total allowable cache of 20 meg, so I don't think the cache size is a problem.

Lastly, I just defragged my 2 disks. It had no effect. Both disks have lots of space.

So, I am fresh out of ideas except that this is just some bug. Anyone else have any thoughts? Maddrummer, ever figure this out?
