I must say...I've never played with the Matrix until yesterday.  I love it.  It was dropping some MIDI notes on Dimension Pro, but audio is fine.  Seems a good practice to freeze all VI's anyway.

MUST TRY MATRIX VIEW...

I don't use the matrix much either except for sampling one in awhile, I don't sample much.
but for plugging in a keyboard and sampling I like it a lot.
its also a great songwriting tool.
I wish my feature request for "marker jumping" makes it through someday.
id love to be able to have jump markers to arrange the way id like.

+1.  I very quickly found myself doing just that...felt kind of weird since I've always worked linearly, but I took to it really fast.

I tried it out today.... I have a blues track with 8 chorus's, it's audio. It's even in tempo and on the grid. I cut the chorus's up and draged each one to a cell in Matrix view.  My experiment is to see if I can choose the length of the tune on the fly for live performance, and yes it all works.... almost
 
It would seem that the first time any cell is played there is an audible pop and crackle sound. Once they have each been played all is fine. but if close the song and re open it, I have to hear the noise once again on the first time a cell is played.....  not good for live performance.
 
any ideas?

That's odd. It sounds like it's having a problem loading the clips first try then once they are loaded up in the RAM or disk cache or where that stuff gets store it gets retrieved more efficiently. Maybe there is a buffer setting somewhere that could be tweaked.
 
However if that's not the case, and to eliminate a couple possibilities, try making sure the audio clips you are using have been split at the starts at the Zero crossings and put a quick fade in. There is also a setting in Preferences (I think under Playback) that let's you set things so when you begin playback at spots that are not a zero crossing it puts a quick fade in right after you hit playback. You can set the length of this fade in (it doesn't effect the clip at all... it just starts at no volume and then turns it up within the time allotted like 25ms for example). You can set it for fade out when you stop playback as well. I used to get pops when starting playback while editing/mixing/whatever. Once I found out about that feature and enabled it all was well. Much easier on the ears and monitors.
 
That's probably not what's happening but might be worth a try. Cheers.

In anticipating that possibility I do have short fades at the heads and tails. I think you're right there is a loading action of sorts required. I'll look over the buffering options....
