Couple Questions

1.) I exported the audio to create an mp3 of my project. When I listened to it it sounded like there were fragmented fx sounds in the background. Like some strange creepy metallic violin playing at random times. It could be "remnants" of my fx in the project but it isn't audible at all when I play it back in Sonar. Also, some of the fx of my plugins wouldn't sound in the mp3. This is strange to me since it sounds perfect when playing in Sonar. In order to get a good mp3 I had to use my sound cards "Record What You Hear". Any idea what might be the problem?

2.) I have 4 different Kontakt windows open for 4 different instruments/sounds for my project. Is there a way to only open 1 window (with 4 open within it) and have it output to the different channels? Or doesn't it matter? I'm worried that it takes more ram to have 4 open than 1...

Thanks a million.

    Instead of exporting directly to mp3, start off by doing a 32 bit export, then re-import that back into that same Sonar project (in a different track obviously).

    The 2 should sound identical (be sure to avoid routing the new track back through any Fx on your Master bus because their effect would then be doubled up)

    If they are the same then you can move on from there.

    After that I'd try a 16 bit export and see how it sounds in WMP or something similar.  Don't forget to dither if you're changing bit depths.

    I have 4 different Kontakt windows open for 4 different instruments/sounds for my project.



    This may be out in left field, but I coincidentally was on the Kontakt forum last night, and saw a post about issues with FX and/or sustain rendering with Player 4.2.3 (IIRC). I didn't follow the whole thread, but just copied the suggested solution for reference:


    "Go to Kontakt 4 options dialog and be sure that 'override instrument's preload size' is checked. I just left it at 60k and now I can render/mix no problem!"


    I'm not sure if this is related, but it would be worth detemrining whether you can reproduce the issue using different synths.


    Also, I trust you're doing a Fast Bounce...? Real-time bounce and MP# encoding are not very comptible, although it can be made to work if you increase you audio buffer size.


    For all the above reasons, it might be advisable to freeze the synth tracks (or bounce the whole project to a "master" track) first to make sure the rendering to WAV sounds good, and then export the frozen/bounced project to MP3.

    I'm not sure what's wrong. I tried all of your suggestions and still had the noise in it...

    What I did do that worked was I unchecked Fast Bounce and exported the audio to a wav file. That worked well. Not sure why that would be the case? Any ideas?

    You could try "save as" then render your effects and export the new project.

    Freeze all your tracks.

    Export, and check all the boxes so there isn't anything else added or subtracted.  Export the same depth and rate as your project. 

    Import the file back into your project.  Now switch using mute between the two.  They should be exactly alike.  If not, go back to your export boxes, look at your routings, etc. etc.  The problem is there.

    If the export is fine, then use that file to do an mp3 export.  If the noise shows up now, it is in the mp3 process.  If you are running close to 0 dB that can induce artifacts. Check the mp3 rate - 320 should be almost exact.  Lower quality renderings cause more artifacts.

    It is a step by step process to find the problem, but the only sure kill method.  Of course, once you figure it out, you shouldn't have that problem again.

    That's pretty simple; You can open 4 different instruments inside a single instance of Kontakt, and then set each instrument to a different midi track (you change the midi channel setting under the instrument name, just to the right of that little wrench icon thingee). Of course, you will need a different midi track set up in Sonar for each separate instrument.
     
    At some point you will probably also want to assign each instrument to its own audio output -- do this with the Output setting that i just mentioned. Again, you will need to set up new audio tracks for each separate instrument if you do this.
