I don't see ATM any reason to put restrictions on N (apart from some reasonable maximum). One thing I can imagine is that the internal processing would be in groups of 4 channels to exploit SSE. But even in that case the interface could be 1,2, or 3 less. On the other hand, this makes a case for using an interleaved format, and for rounding up the number of _physical_ channels if the number of _logical_ channels is not a multiple of four. In other words the host would just provide some dummy channels allowing the plugin to use groups of four without having to copy on input an output. Just a silly idea, but I'm considering exactly that for the internal organisation of an app I'm working on. But then there are also the graphical CPUs today, again changing the picture.
