rj_swarf
--------

This is a kind of LP filter module. It has a sleeper built-in. Put it after
an oscillator or well-behaved signal.

The module smooths the high frequency waves that will be sent to waveshapers, in particular the rj_curver. If your oscillator already has wave smoothing on, you don't need this. If you find that your low notes sound fine, but your high notes have many unexpected components, you may find that rj_swarf tames them. rj_swarf may also be useful for synthsizers using ring or amplitude modulation.

The Input pin is the signal from the Oscillator. (If the signal is not within the normal range, there may be clipping.)

The Pitch pin should be the same pitch as the oscillator's input (i.e. MIDI + 
any transpose/detune). When the pitch is less that 5V, there is no filtering.
When the pitch is > 6V, there is a 1 sample delay added which smooths the highest frequencies. Between 5 and 6V the effect is introduced gradually.

The Wake pin is used by the sleeper.  Connect all ADSRs that are connected to your VCAs (or equivs) to the Wake pin, and when they finish (i.e. when there is 0Volt signal from the summed ADSRs) and they go to sleep, the rj_swarf's output will also go to sleep. This will cascade to subsequent modules.
