fffb~ Fast fixed filter bank Fast fixed filter bank. fffb~ implements a bank of bandpass filter objects (essentially the same as reson~). The input signal is applied to all filters, and the outputs of each filter are available separately. This object is more efficient than using a number of reson~ objects, but does not accept signals for parameter changes.	from the library : MSP Format : External Environment : msp commercial Max 4.x http://www.cycling74.com
