Is there a place in the Cakewalk Universe where it explains how to use a VST arpeggiator?

Hi. The online documentation is here.

All the best.

I installed Cream demo yesterday, played around with it, and got it working to where it plays an arpeggiator pattern.  I created 2 instrument tracks. First track is Z3ta2 but any Cakewalk synth should work.  Track 2 is Cream.  I enabled echo input on both.  On Track 2 I set Midi In to the channel 1 that my Midi keyboard is sending.  I opened up the Cream VST in track 2.  At the top is a VST drop down menu where I checked "Enable Midi Output".  (This is important and I was wondering if you had done that.)  Just a little below that inside the VST GUI is Midi Input and Output which both seems to default to 1 which I left as is.  I set track 1 Midi Input to Cream 1 MIdi Chan 1.  I can then hold a chord on the midi keyboard and hear a pattern playing.  So at this point, it seems to be generally working.  
 
So now I'm venturing into trying to understand how to play other patterns and modify them to my liking.  I opened the Cream VST again, the Preset shows ----- which I believe is the default pattern.  If I click that area, I get drop down showing Factory Bass, lead, rhythm and misc patterns.  Choosing them will play different patterns if I hold some keys down.  One unsolved problem I occasionally have is when I choose the right and left arrows to choose a pattern, Sonar sometimes crashes.  But if I click the drop down to select a pattern it seems ok.  I figure I can work around that and hopefully figure more out later.  
 

I don't use the arppegiator much. It's useful to know you can control the pitches the arppegiator can use.
