Pipeline, good thoughts! But it is useless in the big picture. Random Access is about 20 times faster than SSD. Every schoolboy and schoolgirl knows that (well almost). I do not need to prove it to myself. I know it will be lightning fast compared to current way.

Charlie, no disrespect, but I think you are a little bit jammed up in the way of thinking about this. I said, it would be logical to have a CHOICE between working with active tracks in memory OR from hard drive (just he way you like it). This should be relatively easy to implement.

If done from the memory, I believe it would solve the selected part "re-genereation". It would just not be an issue. It can render items everytime you click on the specific bar, to play from that bar with newly added changes or such.
