In particular I have just started messing with Dimison Pro and I have a million questions.  Is it multri timbial and how do I use assign the sounds to different channels ect.  I just downloaded the newest Platinum version and the control center has  ver 1.5 to download.  How do I tell which version I have now?  And what do all those knobs really do??  You should get the idea.  I need a complete manual on this one synth.  I also quite frankly need it be the one titled Dimison Pro for dummies!!

With the DimPro UI in focus press F1 to display the help. Click the "Dimension Pro" in the upper-right of the UI to display info about the synth.
 
A good resource for the synths bundled with SONAR is Simon Cann's "Cakewalk Synthesizers: from Presets to Power Users"
 

 
There used to be a video on Dimension Pro in the Cakewalk store but for some reason it's now gone.
 
It was probably SWA's "Dimension Pro In Depth" which even SWA now no longer sells.  It was down to 5$ the last time I saw it.  Chapter 2 of the video is available on Youtube.
 
There is chapter 12 of this video : SONAR X3 Advanced Workshop: Virtual Instruments Revealed Video for 10$.  This is by the same author as the previous video so maybe chap.12 is the original Dimension Pro video but I don't know.
 
 
 

I just reloaded my computer, which included X3, and Dim Pro 1.5 (the most current release for it), and the help file did not load with the install.
 
I had an error message about not being able to locate the help file, and ended up downloading it from the Cakewalk site.
 
Here is the link to download the help files for Dim Pro 1.5:
 
https://www.cakewalk.com/Support/Knowledge-Base/2007013200/Dimension-Pro-1-5-Help-files
 
The article for the above link also states:
 
"The D-Pro 1.5 ESD installation does not install the help documentation automatically."

Once you get the "Dimension.chm" help file into the right place "[Cake dir]\Dimension Pro\Documentation",
for the help file to load on F1, you have to first rename the file to "Dimension_Pro.chm".
 
 

thanks to all.  I do believe this forum is going to be a big help!
