When you double-click an icon, it turns gray, and you see its parameters in the lower half of the editor. Here you see the parameters of the Sample module--the module that is playing back the digital recording of whispered speech. The parameter fields with light blue backgrounds are "hot" parameters--meaning that they can be controlled in real time through MIDI (including keyboards, faders, sequencers, or MIDI files). Parameteres can also be controlled by other signals in Kyma--similar to the idea of a control voltage in an analog synthesizer.
Because the Gate parameter is set to the value !KeyDown in this example, the sample is gated on as long as any MIDI key is held down. If you hold down the key long enough, the sample will start looping. The start point of the loop is controlled by a slowly changing signal called "ramp" (a linear function that goes from 0 up to 1, where 0 is the beginning of the sample and 1 is the end of the sample). That's why you can hear the sample repeating and getting shorter each time in the "filter resonances controlled by MIDI" sound example.
