Hi all,
I have a midi drum track in a song that I'm trying to render down to individual WAV files per drum kit piece with BFD3.  In a previous thread, I was struggling to configure BFD3 to route individual drum pieces to separate audio tracks in Sonar, but that's working now via the gracious help on this forum  (http://forum.cakewalk.com/Export-BFD3-to-separate-tracks-sounds-fuzzy-m3550010.aspx)  When playing the song, BFD3 correctly routes the MIDI drum track to individual audio tracks in Sonar - everything plays fine.  HOWEVER, when I arm those audio tracks and try to record the MIDI drum track, Sonar's audio engine immediately halts.
 
I've tried increasing / decreasing audio buffers, disabling FX, increasing record buffers in Sonar from 256 to 512.  I looked at the MIDI buffers, but it was set to the max value already (128 I think?).
I also tried just using the export function within BFD3 and that didn't work either - the individual WAV files were created (I can see them on the disk), but when I try to play them back - no audio.  I thought maybe there was a bit depth / sample rate mismatch, but don't see anywhere in BFD3 to adjust that when it's being used as a plugin within a host (only when it's being used as a standalone VST does the sample rate option appear).
 
Any other ideas?
 
Thanks!

You don't arm/record the audio output tracks to create wav-files, you either bounce to tracks or freeze. Just like with any soft synth. I'm not sure if you can freeze individual tracks in such a case, or if you must freeze the whole synth.

Ok - thanks.  You can clearly tell I don't use soft synths much at all - I'm usually a digital audio guy. 
 
I had done this before with keyboard parts, so naively assumed drum softsynths would be the same.  I'd route the MIDI keyboard track to an audio track with the soft synth loaded, arm the audio track for recording and press record - the audio track with the soft synth loaded would record the audio.  I also saw a BFD3 youtube video (with Reaper or ProTools IIFC) arm the tracks to record and as it was playing, so assumed Sonar would be similar.
 
I'll do some reading on use of soft synths with bounce to tracks or freezing.  Thanks!

So.... I froze the BFD3 synth - it took a long time! (25 mins), which led me to believe something was odd. 
Sure enough, Sonar's audio engine crashes whenever I play back the rendered BFD3 audio,  Unfreezing BFD3 (which removes the rendered audio) restored stability and everything played fine "live".
 
After unfreezing the synth, I noticed when playing the MIDI data through BFD3 routed to individual Sonar tracks, all BFD3 waveforms display as stereo in trackview with waveform preview enabled, despite me selecting all audio outputs to be mono in the synth rack's open synth dialog.  I also checked each drum kit piece output is set as mono in BFD3, except for the overhead ambient mics, which are stereo.
 
As a test, I manually created a mono audio track for the snare, set the input to BFD3's snare kit piece output and the waveforms still display as stereo with preview enabled when playing the MIDI data through BFD3. 
 
I'm not sure, but suspect whatever's causing the mono / stereo mismatch is contributing to the rendered audio being unplayable.  I'm clearly doing something wrong and am getting desperate.  I have to send the rendered audio in an OMF to an engineer asap. 
 
I'll try converting the stereo clips to mono to see if that helps, but am curious if anybody can detect what I'm doing wrong in my routing, as I have many other songs to render.
 
Any help would be greatly appreciated.
 
Thanks
Russ
 

Don't freeze. Just bounce to tracks. Bounce ONE TRACK AT A TIME by soloing the part of BFD that you want to bounce. And then after you have the tracks bounced, just click the mono/stereo button in the channel. 
 
How big are your projects? What else is going on? Is your UAD causing it? Disable UAD plugs and try again. Try it on a single track project, for example. 
 
I've never found freezing helpful. A bounce is just as fast to me. 

Thanks for your response. It's working now - not sure what it was to be honest.  I did find my render bit depth was set to 64 bits in preferences->audio data, so that likely is why it's taking so long.  Shouldn't affect playback after rendering though. 
 
As stupid as this sounds, I clicked the freeze button on a synth track instead of clicking on the actual synth in the synth rack.  Either that or changing the rendering bit depth seems to have done the trick.  Strange.
