The Kyma Language for Sound Design, Version 4.5

Now, try the following:
♦ Bring up !F1, the amplitude of the first harmonic to about half way. (You should see periodically
spaced vertical lines)
♦ Bring up the amplitude of !F8, the 8th harmonic to about 3/4 of the way up.
♦ Set !F4 to about 1/4 of the way up.
♦ Set !F12 to its full amplitude of 1.
What you see is a picture of the spectrum repeated 32 times across the width of the oscilloscope display.
In fact, you should be able to create a kind of “shape” using the fader settings and see it repeated in the 32
spectra. Try this right now. Set !F1 to its maximum value, !F2 to just slightly less than that, !F3 to
slightly less, and so on until !F15 is just above zero and !F16 is set to zero. You should see a kind of
sawtooth shape repeated 32 times in the oscilloscope display.
Cautiously bring up the gain on your amplifier (not too fast or your ears will be very sorry). You should
hear a very high pitch. How high? Well, the period is 16 samples long. So this seems like the perfect opportunity
to employ your Kyma-calculator text file. Enter the expression:
16 samp inverse
select it, and use Ctrl+Y to evaluate it and see what the frequency is in hertz.
The output of the left channel of the SyntheticSpectrumFromArray is:
amplitude1, amplitude2, ... amplitude16
repeated every 16 samples. The right channel (not shown on the oscilloscope) is:
frequency1, frequency2, ... frequency16
We take a closer look at this kind of spectrum format later on, in the section called Live Analysis, Resynthesis
on page 131.
But for now, take a moment to try out the other audio demonstrations (or make a note to come back to try
these later, once you have finished the rest of these tutorials). For some of the examples, you may need to
click the grow box on the virtual control surface in order to be able to read all of the text and have more
detailed control of the virtual faders.
