I am running Sonar 6 (64bit) on Windows XP.  When I am recording I will often experience this:  I will see the recording in progress and everything seems to be running smoothly, but once I hit the space bar or press the stop button to stop the recording, the part I just recorded will instantly delete/disappear with no trace of it ever being there.  This doesn't happen all the time, but very often.  Any clue why this is happening??

Is this audio or midi or both?

You're not doing what I was, which is to have the autopunch enabled but trying to record to a different part of the track?

Drove me nuts and I was convinced Sonar was a piece of junk. Boy did I feel stupid...

Recording seems to go perfectly - waveforms are drawn correctly etc. but immediately after recording is stopped whole take just disappears.

I had this issue last weekend. I recorded audio 15 minutes (14 tracks, 44,1k/24) and after I pressed Spacebar all recorded data was lost.  I checked the Audio folder: files of the lost take are there but their size is 4 kB.

For me this happens ONLY at the first time when Sonar and project is opened.
I'm also almost sure that it has something to do with audio drivers. Try changing settings in Options / Audio.

My setup: Win7 64 bit, Sonar 8.5.3 PE 32 bit,  2 x RME Fireface 800 / ASIO

Nope, Auto-Punch is not enabled.

Audio.  I never really use Midi so I'm not sure if it would happen to it as well.

I wish it only happened the first time I opened a project!  It happens randomly.  I have my driver mode set to ASIO as well - always have and have never had a problem until now.  It just doesn't make sense.

I have never, not even once, had this happen...Not sure what you're doing wrong but you're doing something wrong...

I have met this issue many times and in my case it has most probably something to do with interaction between Sonar and RME ASIO driver.  This is quite painful bug: you can't predict if recording is going to be succesfull before you stop it.


JComissio,

Try tweaking RecordPreAllocSeconds parameter in aud.ini and see if it helps.  (Audio Options / Advanced / Configuration settings: Edit Config File) If not, turn off "Share Drivers With Other Programs" and "Use Multiprocessing Engine". Enable "Always Open All Devices".

Delete everything in Picture Cache folder. 
Uninstall & reinstall audio driver.
Disable Windows Sounds.
Defragment disks & check for errors.

Maybe something of these will cure...

Panu, 

I can't find "RecordPreAllocSeconds" parameter.
