7 - Filter

Another brief update. A filter has been added which has many different modes, it can define and modify a sound very simply and effectively. The filter object itself is 'biquad~', a two-pole, two-zero filter. By using a 'umenu' object (a user created drop list menu), different filter types can be enabled and selected. 'filtergraph~' is a very useful object that serves as a graphical display of cut-off and resonance values and can also be used as a user interface to input changes.

The signal from the oscillators has simply been connected directly to biquad~ and out of, straight into amplitude scaling multipliers (*~).
