When i record from mic the innterface chops the audio signal 96times per cycle when set to 96khz ample rate. When bouncing a midi track, does it do the samething?

Don't know for sure, but I think it will bounce at the set rate for the project.  Perhaps someone who knows for sure will chime in soon.

I assume it depends on the soft synth used. Some don't support 96 kHz, AFAIK, but also AFAIK, the resulting audio
is 96 kHz, as otherwise you could not play it back in a 96 kHz project.

And again AFAIK, the interface is not involved in bouncing soft synths, as you can do a bounce or export even without the interface. It's only processor work. BUT...I may be wrong :o/

it is 96 THOUSAND time per second.... not 96. 

That is the AUDIO sampling rate. It takes the audio coming in and samples it at that rate to reproduce it in digital form for recording. 

The higher the sampling rate, the more accurate the picture it can paint. However, the normal rate for CD of 16 bits and 44.1k sample rate is more than sufficient to reproduce a highly accurate and detailed musical note.  That's why it's a standard. Commercial CD players are all set up to read that particular standard. Other non-standard rates may or may not be read on a given machine. Although a computer will generally read them.

Going above 44.1khz is OK, but 99.9% of listeners can not differentiate between a 44.1khz sampled recording and the 96khz ones in a side by side listening test with any degree of accuracy beyond the random correct guess. 

Midi is already digital. However, coming out of the DAW, when it is converted back to audio, yes, the sampling rate selected is used to convert the digital back into audio..... that is why you select a bit depth and sampling rate to export to audio. 

I agree that this is really a non-issue. The DAW may simply use the soft-synth plug-in to "generate" the audio at its best sampling rate up to the frequency of your session, such as 96Khz. But even if the MIDI audio is compressed, as most of them are, it's processed into your song vs sampled and caught as actual audio. I don't really think you'll be able to really control all this, so I'd place more emphasis on the recorded audio sampling vs. MIDI.

When you bounce a MIDI track, the DAW is merely generating the audio for your session and storing it now as actual audio in a track. I believe this should end up being the same rate, but you can check this by zooming way into the MIDI track and see if every two samples are exactly the same level when compared to your other 96Khz audio. If only every other sample varies from the last, then it could simply be a 48Khz signal resampled at 96Khz. 

For me, I would forego the Bounce and let MIDI play the notes during Mixdown. 

MIDI triggers sounds generated by the synth. Each synth has already been set with the sounds it makes. This can be sampled sounds or synthesis. This can be analog or digital etc etc. 
Your project sample rate has zero to do with this. 
Word length can be anywhere from 8 bit to 32 bit. That's more important than clock speed. Sonar works in 32 bit but that still only counts with an audio track. 


Using a higher clock rate beyond 48 hz is a well documented waste of hard drive space for most of the recordings made with home studio equipment. Might make a .5% better sounding recording. 

All of the audio in your project must be at the same sample rate. If you've set the project SR to 96KHz, any audio brought in will be converted to 96KHz by SONAR, regardless whether it's recorded audio, an imported file, or rendered synth output.
