Description:

;=============================================================================
; ADD-1.ORC
; SIMPLE ADDITIVE SYNTHESIS (FROM ACCCI, 02_01_3.ORC) / MONO
; AMPLITUDE ENVELOPE WITH OSCILI
;=============================================================================

; Timbre: gong
; Synthesis: additive same units (02)
; basic instrument( 01)
; Source: #420, Gong-like Sounds, Risset(1969)
; Coded: jpg 8/93, 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 Lisp 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 = maximum amplitude [linear, 0.0 -> 1000.0]
; p5 = frequency [Hz]
; p6 = amplitude envelope [GEN number]
