In the attached image, I've circled some doo-hickies. I thought they were called 'track icons,' but since track icons can be changed, I'm assuming those are the larger images below these doo-hickies. BUT...
What I really want to know is: what do these particular ones mean? Is there a reference somewhere that conveys this information? I've looked through the reference manual, but since I don't know what to call them, I'm not sure where to look.
Background: I've been away from Cakewalk for far too long and now I'm trying to revive some of my old projects so I can get used to things again. Trouble is, I'm using a different computer than I had last time (five years ago??) and on the old computer, I was using Sonar X3, X2, X1, Plat, etc. so a lot of the soft synth stuff is silent during playback. I've been madly installing plugins, but even after they're installed (particularly: Garritan Personal Orchestra 1, EZDrummer 1) I'm having (I think) routing issues. I'm trying to understand what the icons mean so I can get to the bottom of it.
the top two tracks are from a new project I set up to see how things are done automatically when adding a soft synth
the bottom two tracks are from one of the old projects where the soft synths don't work
Any help will be muchly appreciated.
