object MoogFF extends Serializable

A Moog VCF style UGen. This is a type of resonant low pass filter.

The design of this filter is described in Federico Fontana, "Preserving the Digital Structure of the Moog VCF." In: Proceedings of the ICMC, Copenhagen 2007. Ported to SuperCollider by Dan Stowell.

Examples
// mouse controlled
play {
  val in   = WhiteNoise.ar(01.1)
  val freq = MouseY.kr(100, 10000, 1)
  val gain = MouseX.kr(0, 4)
  Limiter.ar(MoogFF.ar(in, freq, gain))
}

    gain

    filter resonance gain, between 0 and 4

    reset

    when greater than zero, this will reset the state of the digital filters at the beginning of the next control block.
