PLUCK-1

CLASS SLOTS:
- self Synthesis event [default = NIL]

ARRAY SLOTS (KEYWORDS):
- e-dels Entry Delays [sec] [default = 0]
- durs Durations [sec] [default = 1]
- amp Maximum Amplitude [lin, >0.0-1000.0 or dB <= 0.0]
[default = -6.0]
- freq (Minimum) current frequency [Hz]
[default = 440.0]
- dec Decay time/% of the total dur of the amp envelope [sec/%]
[default = 0.8]

Description:

;=============================================================================
; PLUCK-1.ORC
; PLUCKED STRING USING THE KARPLUS-STRONG MODEL
; (FROM ACCCI, 15_01_3.ORC) / MONO
; AMPLITUDE ENVELOPE WITH LINSEG
;=============================================================================

; Timbre: Plucked string
; Synthesis: Karplus-Strong algorithm
; PLUCK
; LINSEG envelope, cembalo sounds
; 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
; 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 = frequency [Hz]
; p6 = intended freq value [Hz]
; p7 = % of the total duration used for the last decay [0-1]
