20 /* configuration of instruments
21
22 you may combine the first eight harmonics in whatever proportions you wish
23 to make a carrier for your instrument. magnitudes are proportional, so
24 2,1,0,0,0... means two parts harmonic zero plus one part harmonic one, for
25 a total of three parts or 0.666*f_0 + 0.333*f_1. Actually the coefficients are
26 squared to compensate for lack of dynamic range (0-255).
27
28 you may choose sine, square, saw, triangle or noise as the basis function or
29 choose any previously defined instrument. choosing a future instrument will
30 result in an undefined instrument.
31
32 you may choose a frequency modulation signal the same way as you choose a basis.
33 FM_OFF is a special value to choose no FM signal. the value after the FM signal
34 is the frequency of the FM signal. The frequency is determined logarithmically
35 via F = 2^(value/8).
36
37 The next two values determine cutoff frequencies for the instruments low pass
38 and high pass filter. 0 deactivates the filter, otherwise F = 2^(value/8).
39
40 At this the the last four numbers are useless.
