Hi ALien,
I have already thought about this option, and while it would be great to have, I have decided against inplementing it for a very specific reason.
All existing flash chips, and so also the one in the BCR, only have a limited life in terms of writes (usually a couple 100.000). While through regular use you are hard-pressed to ever reach this limit, with an Autosave function it would definitely be reachable, and it´s hard to say how fast. If you picture using Autosave in conjunction with pattern chain, you can imagine that you can get heaps of writes in a very short time. While I could just put the info into the manual, I doubt that it would reach every user of the Zaquencer, so I decided not to provide the function in the first place.
