p0  = output start time (seconds)
   p1  = input start time (seconds)
   p2  = input duration (seconds)
   p3  = amplitude multiplier (relative multiplier of input signal)
   p4  = ring-down duration (seconds)
   p5  = FFT length (samples, power of 2, usually 1024)
   p6  = window length (samples, power of 2, usually FFT length * 2)
   p7  = window type (0: Hamming, 1: Hanning, 2: Rectangle, 3: Triangle, 4: Blackman, 5: Kaiser)
   p8  = overlap - how much FFT windows overlap (any power of 2)
         1: no overlap, 2: hopsize=FFTlen/2, 4: hopsize=FFTlen/4, etc.
         2 or 4 is usually fine; 1 is fluttery; the higher the more CPU time
   p9  = wet/dry mix (0: dry -> 1: wet) [optional, default is 1]
   p10 = input channel [optional, default is 0]
   p11 = pan (0-1 stereo; 0.5 is middle) [optional; default is 0]

   Because this instrument has not been updated for pfield control,
   the older makegen control envelope system should be used:

   Function table 1 is the input amplitude, spanning just the input duration.
   Function table 2 is the output amplitude, spanning the entire note, including ring-down duration.
   Function table 3 is the EQ table A (i.e., amplitude scaling of each band),
      in dB (0 dB means no change, + dB boost, - dB cut).
   Function table 4 is the delay time table A.
   Function table 5 is the delay feedback table A.  Values > 1 are dangerous!
   Function table 6 is the EQ table B
   Function table 7 is the delay time table B.
   Function table 8 is the delay feedback table B.
   Function table 9 describes the curve between EQ tables A and B.
   Function table 10 describes the curve between delay time tables A and B.
   Function table 11 describes the curve between delay feedback tables A and B.

NOTE: This is an older RTcmix instrument, the newer SPECTACLE2 instrument is probably better to use. The parameter time-variation can be accomplished using the pfield-enabled capabilities of SPECTACLE2.



Usage Notes

See the SPECTACLE Usage Notes of an explanation of the basic parameters of this instrument.

There are two 'sets' of makegen function tables used to specify 'endpoints' for the EQ params (p3 and p6), the delay times for each FFT bin (p4 and p7) and the feedback values for each FFT bin (p5 and p8). Function tables listed in p9, p10 and p11 then specify the envelope trajectory between these two sets. When the envelope in the function table is at "0", values from the corresponding first set (p4, p5, p6) will be used. When the control envelope is at "1", values from the second set (p7, p8, p9) will be used. Intermediate control values will interpolate between the endpoint table values.

TVSPECTACLE can produce either mono or stereo output.


There are no sample scorefiles.
