Description:

;=============================================================================
; ADD-2.ORC
; SIMPLE ADDITIVE SYNTHESIS (FROM ACCCI, 02_41_1.ORC) / MONO
; AMPLITUDE ENVELOPE WITH LINEN
;=============================================================================
; Timbre: Brass
; Synthesis: Additive, same building blocks units
; Basic instrument with added random frequency variation
; Source: #200, Brass-like Sounds through Independent Control of
; Harmonics, 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 printing small values with exponential notation
; Replaced oscili with poscil (precise oscillator), ms 8/08
; Default SR = 96000, recommended precision: 24 bits
