rharv.. Temp or not, they are loaded from a directory on the hard drive, not from memory. (That was confirmed by PG) It is a BIG mystery to me, why they did not make a choice to work with realtracks that are used in the project from memory once they are selected in the project. I believe most of PCs with 8-16gb RAM should handle that option just fine.

Mario, I remember good old tape days pretty well and computers that run on tapes and even know what perfocards and perfotapes are smile

There is overall huge lag in BIAB. To some it feels ok, probably because they got used to it and find all kinds of excuses to justify it. I would prefer it to run much faster, at speeds of modern software. But who am I to judge? Just opinion of how it feels to me.

Different animal, vArranger. Initial startup that takes about 15-20 seconds, to fully load 12gb of sound content into memory, but then it flies.
