Description:

;=============================================================================
; FOF-2.ORC
; FORMANTIC WAVEFORM (FROM ACCCI, 45_01_2.ORC) / MONO
; AMPLITUDE ENVELOPE WITH POSCIL
; CONTROL OF THE DETAILS OF THE FOF FROM THE SCORE
;=============================================================================

; Timbre: Granular synthesis with fof module, voice-like tones
; Synthesis: FOF (Forme d'Onde Formatique)
; POSCIL envelopes
; Coded: jpg 8/92, modified ms 9/04, 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
; NB1: this implementation works with both audio and sub-audio f0's
; and allows for an independent control of tex, debatt and atten
