Step 1:                                                                                                                                                                                                                      

In Step 1 the idea was to generate 64 samples of 10 – 15 seconds in length. It must first be stated that a single Csound orchestra was utilized to render all the samples in this step. Figure 6 is an excerpt of the code:

instr 1 
idur          =              p3
iamp        =              p4
ifreq         =              p5
kbal          =              p6

iatk          =              p3 * .1
idec          =              p3 * .2

 kenv1 linseg             0, iatk,     iamp,       idur - (iatk + idec),   iamp,       idec,         0             

 a1, a2 diskin             1,             ifreq,        0,             1

                 outs          (a1 * (kbal - 1)) * kenv1,         (a2 * kbal) * kenv1

As can be seen this is a simple instrument. It is a stereo sample playback unit allowing for variable amplitude, frequency and static panning on a per event basis in the score. Also there is a duration dependant amplitude envelope meant to smooth any inconsistencies in the samples being used. Four of these instruments were used, all of them identical except for the sample number. 

Mix 0 was begun by writing a Cmask sub-score meant to generate a Csound score that utilized sample 0111, the base sample from Group 1, to render 4 new samples. Figure 7 is an excerpt of the Cmask code (sub-score) used to generate the first score:

 In Figure 8, the row marked “sample” were the names of the original sample(s) and in the row marked “result” were the names of the samples created. Notice the general density designation for each row. The use of colors was implemented to make it easier to spot the origins of the results and later the origins of the reiteration process. 

*The sample numbers in the gray cells are links to an mp3 of the sample.
