Is there a setting somewhere to increase the refresh rate of the bus waveform preview
 
thanks in advance :)

I believe it is controlled by the WavePreviewSampleFrequency setting in Cakewalk.ini
http://www.cakewalk.com/D...p;Req=INI_Files.4.html
Use Preferences > File > Initialization File to change Cakewalk.ini. "Initialization File" is an advanced setting, make sure "Advanced" is selected at the bottom of the Preferences dialog to see the selection.

ty Scook will investigate 

I believe the WavePreviewSampleFrequency variable defaults to the best rate. By default it samples once every 40ms. Raising the value will skip samples.

Hi scook
Yes I just read that so sonars default setting is set to max refresh rate. 
That's a shame. I've set a short loop with one bass note and on each pass the waveform shape varies considerably.
 
The reason I'm doing this is to explain side-chain techniques (kick reducing a bass note) to some students and wanted to give then a visual representation. 

So any other ideas on how I could make the "wave preview" more stable? 

What about creating a groove clip from the audio and roll it out, bounce the tracks to illustrate before and after side-chain. BTW, there is a Cake TV video on side-chaining which does a good demonstration although it does not have a graphic illustration of the effect.

Thanks again scook.
Yes thats exacly what I was doing while waiting for a reply

Again Yes!

• "SONAR Go Deeper - ProChannel Sidechaining" 

also used

• Sonar X1 - Sidechaining in Sonar X1a
• Sonar X2 - ProChannel - Sidechaining - 4 different uses

But still... It would be nice if the "wavepreview" was a tad more responsive
(If only I could fit a turbo charger on it... lol) 
 
Thanks for your input :)
