Description:

;=============================================================================
; BUZZ-2.ORC
; DYNAMIC SPECTRUM OSCILLATOR / MONO
; AMPLITUDE ENVELOPE WITH POSCIL, VALUES IN HZ
;=============================================================================

; Timbre: Various controlled noise spectra
; Synthesis: (g)buzz
; POSCIL envelopes
; Coded: jpg 8/92, modified ms 9/02, 8/08

; 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 = fundamental freq [Hz]
; p6 = amplitude envelope [GEN]
; p7 = lowest frequency in the buzz [Hz]
; p8 = highest frequency [Hz]
; p9 = multiplier in the series of amp coeff for the buzz [0-1]
