Thank's for the heads-up Strummy. Much appreciated.

Too all those interested, after much time spent searching, I have finally found the CHORDS pattern in Sonar X1 Producer.
In the browser area you can find them the following way: 

 A) Sonar X1 producer> ptn midi patterns>pads>chords.
 B) Ptn midi patterns> pads>chords

I also found out that, having the patterns this way, they can apply not only to the SI Instrument Piano but to almost any instrument chosen.
Hope this will help.

Again, Thanks to all.

That's cool Gerry!

Ah! No wonder I couldn't find them.

On my laptop (which only has the 32 bit version installed) they are in:

C:\Cakewalk Content\SONAR X1 Producer\PTN MIDI Patterns\Pads\Chords
