Why is this using so much CPU?

Here are two very simple ensembles, just an oscillator into a filter.

As far as I can see they are exactly the same in every way, but "Example 2" uses about 7% of my CPU, whereas "Minimal filter example" uses about 29%. They are the same filter.


Can anyone explain what is going on?

Thanks

    Dunno, I'm getting about 1.6% cpu usage on both examples on my 8 year old PC...

    can't find anything called "Minimal filter example" though, only two ensembles "filter comparison.ens", and "filter comparison2.ens"

    Thanks for checking it out....

    Sorry I accidentaly attached the wrong files, the correct ones are there now.

    Ah figured it out now anyway.... they are running at different sample rates. Didn't know that the sample rate was saved as part of the ensemble.

    I didn't know snapshots included the sample rate. Are you sure about this? I was thinking you had too many voices or something.

    Not snapshots, ensembles themselves. When you save an ensemble, reaktor saves the sample rate as part of the ensemble.

    I had assumed it was a reaktor preference rather than ensemble-specific.
