Yes, what I don't understand though is _why_ we see such an increase
in CPU load, when the channels are muted.

The tracks are already seperated into abstractions, so this will be
easy to implement.
Since the help for switch~ displays block~-help, I had mistaken the
switch~ object as controlling blocksize as well.
I will implement your suggestions straight away - thanks!
