hypersaw vs. ordinary saw with 8 unison

[grs]

1 voice with hypersaw set at 8 saws will only use one note of polyphony. This will also go through the filter section once and will have no unison spread. An 8 voiced unison saw will have 8 single saws going through 8 filters and be spreadable. Tip, to get a phat 8 saw with hypersaw use 2 note unison with 4 saw hypersaw osc and unison spread that.
So I'd say they are pretty similar, yet the only audible difference is that the amount of filter smearing is less on the hypersaw example. IE cleaner.
