mixing down from midi to audio

I"m in X series Sonar, but hoping in track view, there you can choose the 'track' tab, and select 'bounce to tracks'.
In X series you get a window that let's you choose to bounce to multiple tracks....have a try

have you tried the 'tracks' tab (it's a litle further to the right from the 'edit' tab) ? I'd say 'bounce to tracks' is there...
 

think I got it now, just go to 'bounce to tracks' from the edit menu, just as long as you get the 'bounce to tracks' dialog box....there you can select what you're looking for...

in dialog box did you choose 'new track' on destination + source 'tracks' ?
small chance by freezing the midi tracks, in the freezing Sonar makes them audio files....guess not (can you even freeze midi ?)

Reading your last post I'm not sure if bouncing tracks is what you want to do or something else, but if it is bouncing existing pairs of MIDI and audio tracks associated with a synth, try this.
 
First create a set of new, empty audio tracks starting after the last existing track (so if you've 6 tracks you want to bounce create 6 new tracks, numbered 7-12).
 
Select the tracks you want to bounce so that the blue indicator where the track number is lights up. Make sure that at least one, better all, trakcs have enough blank space at the end to accomodate any effect tails from delay, reverb etc.
 
RIght click on a track header and select "bounce to tracks" or pick it from the tracks menu in the main or tracks screenset. In the bounce dialogue select "tracks" as the source. Sonar will fill in the box with the selected tracks.
 
For the destination pulldown menu select the first of the new, empty tracks.
 
Then bounce. If your copy of Sonar works the same as mine just did when I tried this (and if my explanation's clear enough) it will then bounce each selected track into a different destination track, so track 1 gets bounced to track 7, track 2 to track 8 and so on.
 
Alternatively, you could just go down the relevant synth tracks hitting "freeze" for each of them, which is quicker than bouncing a track at a time and will do pretty much the same thing.
 
 If you want to record MIDI into audio "live" then Sonar doesn't work like that. Which is a bit of a debating point round here at the moment :-). Basically, to convert a synth to audio you bounce the synth's MIDI track and the audio track that contains the synth. Or if you're using the combined "instrument" tracks then you bounce them.

I'm not sure now, but I assume the MIDI tracks should all be on separate MIDI channels in order to be bounced on separate tracks (??). The OP doesn't tell if that is the case. I'm almost sure I've in the past bounced to separate tracks that way and choosing "Tracks" as the bounce source.

Good point Jonesey.
Paul, which synth are you using?
What you are describing would be the expected behavior for TTS-1 with all channels set to output 1.
I suspect your problem stems from a configuration issue.
Tell us what you are working with, and please include as much detail as you can.

i always use separate channels for my midi tracks. but according to a friend of mine, i need a soundcard with multiple outputs (or softsynth) to bounce/record multiple midi tracks into multiple audio tracks in one single operation.

i'm not using any synth, just the sounds from my all-in-one interface/soundbox. that may be a part of the problem, since it doesn't have multiple outputs.

i'm using a roland sd-50, it'a combinated soundcard/interface with integrated sounds. my midi tracks outputs are set to this device.

Well, in Roland style, the manual is somewhat vague.
It appears that your synth may have 4 virtual outputs (1L,1R,2L,2R). You would need to assign the instrument outputs in the SD50 to one of these.
in Sonar8.5, click Options>Audio>Drivers.
What do you see?

Hay all.
Not sure about this, I did try it out, and it seemed to work for me...as I do not know how to yet bounce midi to audio yet in sonar.
 
I opened up a old midi file of xg type to play with vsti and get to work on setting it up with differing things like AD2 for drums.
 
I was able to select the AD2 output as a audio track input...and record it.
Did that for the bass, Viola, and Cellos....Worked ok for me so far.,....But I do have a very good audio setup with lots of ways to route things.
 
Just thought I would chime in...just in case all else fails.

That's it in a nutshell, Steve.
Even the Op suggested he may be barking up the wrong tree in an earlier post.
It boils down to what outputs the SD-50 presents to Sonar.
As Johnny noted, it would be much easier to use VST instruments such as TTS-1.
The exciting thing here is that I think Paul is on the verge of discovering just exactly what he has his hands on.
