Description:

;=============================================================================
; SUB-1.ORC
; SUBTRACTIVE SYNTHESIS OF RANDOM NOISE (FROM ACCCI, 50_01_1.ORC) / MONO
; AMPLITUDE ENVELOPE WITH OSCILI
;=============================================================================

; Timbre: Bands of noise
; Synthesis: Subtractive synthesis
; Basic design
; RAND source
; 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 = centre freq [Hz]
; p6 = bandwidth [% of centre freq, 0->1]
; p7 = amp envelope [GEN]
