This is probably the clearest explanation of sampling and band-limited synthesis I have come across.
Yes! I got a lot out of watching the Monty Montgomery video that he refers to as well.
Going a little further on the bit depth aspect, I found the following useful on understanding 32-bit floating point vs. 24-bit considerations: 32-bit float recording depth vs. 24-bit: Complete Beginner Guide
And how that affects headroom, clipping, and gain settings:
As I have this video playing I am setting up an octatrack set-up with 16 bit 44 khz so I know for sure I get as much sample artifacts as possible.
