Mixer
In the mixer you control the volumes of both waves and the noise generator. An optional
ring modulation extends the tonal range of the MicroWave II/XT/XTk.

Ringmod
Volume of the ring modulation between Wave 1 and 2. From a technical point of view ring
modulation is the multiplication of the waves' signals. The result of this operation is a
waveform that contains the sums and the differences of the source frequency components.
Since the ring modulation generates disharmonic components, it can be used to add
metallic distorted sound characteristics. This is useful e.g. when generating synth
percussion. The following diagram illustrates what happens when two sine waves are ring
modulated. Please note that in a complex waveform all harmonic component behave like
interacting sine waves, resulting in a wide spectral range of the ring modulated sound. The
following diagram illustrates the ring modulation of two sine waves:

Noise
Volume of the noise generator. The noise generator produces pink noise and features no
other controls. Noise is a fundamental source for any kind of analog-type percussion. Also
wind and other sound effects can be created by using the noise generator.
External
Volume of the external audio input Analog In
sound source, you still have to trigger the MicroWave XT's envelopes to get the signal
passed through. Though you have to generate MIDI notes either by a connected sequencer
or the internal arpeggiator.
