I do know that generally once channels are allocated they won't move. So the question is if it will begin to allocate channels to the smallest DSPs first or not, to which I would not be surprised if it did work like that. I've not been privy to the allocation magic of the PVDM3's, so it would be a cool test if you've got the ability.<br>

The PVDM3's are good because you don't need to drop $100k on a MCU to get started. There's also Callway and others are hosted services that partners offer that you can pay-as-you-need or pay-as-you-use.<br>
