OK, thanks guys.
Essentially I think NO is the answer.
The MATRIX view I dont think will work either?
In the case of the image shown in OP its one continuous MIDI note ( not sample ) for 4 bars playing an evolving ambient type synth sound. It starts quieter and then builds in bar 2 and 3 then fades in bar 4. By using the standard loop thing it plays in with bar 1 but then loops the evolved "full" sound in bar 2 and 3 continuously which is the exact "sound" I want looped for the whole ambient piece as an underlying soundscape.
Think of it this way, the sound builds UP in bar 1, then plays full volume in bar 2 and 3 before fading in bar 4.
I tried to freeze it, split it at start of bar 2 end of bar 3 and then drag drop that middle part to the MATRIX. Yes Matrix continuous looped it but when it hit end of loop you get that "glitch" as it ends coming back around to start.
By looping the 2nd and 3rd bar of the one midi note w/o freeze you get a seamless continuous play.
So hope that explains it a bit more ..
