The Wave dial allows you to interpolate between the two basic waveforms.
When the dial is at its leftmost setting, the waveform consists of purely the
first waveform. Similarly, if the dial is moved all the way to the right the
waveform consists of purely the second waveform.
When in an intermediate position, the waveform is a mixture of the
harmonics of the basic waveforms. It's probably easier to see this (in the
display) rather than explain it, so try it for yourself: Set one wave to Sine (in
the Dark category) and the other to Sawtooth. As you move the Wave dial
from one end to the other you can see the wave changes between Sine
and Sawtooth.
The Symm (symmetry) dial right next to the display changes the waveform
symmetry. As the waveform display also shows the current symmetry
setting, we suggest you just play with dial with having two clear basic
waveform as Sine and Sawtooth to see how it affects he waveform. It's
pretty straightforward.
The F (free-run) button – located on top, just right of the oscillators label -
determines if the oscillator is re-triggered or not. When the Free-run button
is Off, the phase of each note is reset at each onset. When the Free-run
