The Kyma Language for Sound Design, Version 4.5

MIDI Controllers
The output of any Kyma Sound can be used as a MIDI continuous controller output. In other words, its
stream of instantaneous amplitudes can be sent out as changes to a continuous controller (at the maximum
MIDI rate of 1 khz and with the maximum MIDI controller resolution of 7 bits).
If both the Capybara and your synthesizer are patched into a mixer, you can listen to both at once. Otherwise,
you will need to send the output of the synthesizer into the Capybara’s audio input. Then you use
one of the Kyma software Mixers to mix the ADInput (which will be monitoring the synthesizer) with the
Kyma Sound that is sending out the MIDI controller data. §
Here is a typical configuration for listening to the output of a synthesizer that you are controlling using a
Kyma Sound:
MIDI Keyboard Events
To generate a MIDI keyboard event, you have to supply a pitch, a velocity, and a trigger (which indicates
when to send this information as a MIDI note event). As a trivial example, suppose you had a MIDIOutputEvent
whose Frequency was set to !Pitch, whose Amplitude was set to !KeyVelocity, and
whose Gate came from !KeyDown.
§ Anytime you want Sounds to play simultaneously in Kyma, you have to put them into a Mixer — even if one of the
Sounds (in this case the MIDIOutputController) is not actually producing an audio signal that you can hear. Even
though its output is going to the MIDI output rather than becoming part of the audio stream, its program does
have to be loaded in the Capybara at the same time as the program for reading the ADInput. You can read more
about this in Combining Sounds on page 70.
