Description: ;============================================================================= ; FOG-1.ORC ; GRANULAR SYNTHESIS (NEW INSTRUMENT) / MONO ; AMPLITUDE ENVELOPE WITH POSCIL ;============================================================================= ; Timbre: Granular synthesis with fog module, voice-like tones ; Synthesis: FOG (Forme d'Onde Granulaire) ; POSCIL envelopes ; Coded: ms 9/02, 2/09 ; NB: ; this instrument works AT BEST with samples whose length is a power of 2 ; those which are shorter than the immediately superior power of 2 accepted ; by the GEN01, will produce silence when looking up the unsued portion of the table ; NB1: 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 = maximum amp [linear, >0.0-1000.0 or dB, <= 0.0] ; p5 = density of the grains [Hz] ; p6 = transposition factor [1=original] ; p7 = bandwidth -> exponential decay [Hz] ; p8 = audio file [GEN01] ; p9 = speed of the starting pointer in the file [1=same as original] ; p10 = amplitude envelope [GEN] ; p11 = rise time of the grain envelope [sec] ; p12 = overall duration of the grain [sec] ; p13 = decay time of the grain envelope [sec] ; p14 = octaviation index [>= 0.0] ;----------------------------------------------------------------------------- ; COMPULSORY GEN FUNCTIONS ; f31 audio file ; f19 sigmoid rise/decay shape ;_____________________________________________________________________________ | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
