Description:

;=============================================================================
; RANFL-1.ORC
; FREQ LIMITED RANDOM NOISE FILTERED BY A CASCADED RESON AND FOF FILTERS / MONO
; AMPLITUDE ENVELOPE WITH POSCIL
;=============================================================================

; Timbre: Formantic subtractive synthesis with noise
; Synthesis: randi with cascaded reson and fofilter
; POSCIL envelopes
; Coded: ms 2/09

; NB: NEW STRUCTURE FOR THE AMPLITUDES FROM AUGUST 2008!
; Positive value > 0.0 : linear amplitude (>0.0-1000.0)
; 0.0 or negative value : amplitude in dB (0 = maximum value)

; The apparently arbitrary amplitude range (0-1000, rather than 0-1)
; avoids printing small values with exponential notation

; Replaced oscili with poscil (precise oscillator), ms 8/08
; Default SR = 96000, recommended precision: 24 bits

; p1 = instrument number
; p2 = action time [sec]
; p3 = duration [sec]
; p4 = max amp [linear, >0.0-1000.0 or dB, <= 0.0]
; p5 = freq of the noise [Hz]
; p6 = centre freq of both filters [Hz]
; p7 = bandwidth of the reson [Hz]
; p8 = amp envelope [GEN]
; p9 = impulse response attack time of the fofilter [sec]
; p10 = impulse response decay time of the fofilter [sec]
