Osc2
Volume of Oscillator 2.
Osc2 Balance
Determines the ratio of the oscillator's signal that is sent to the inputs of Filter 1 and Filter 2 (see
routing picture). If set to F1 64, the signal is sent to Filter 1 only. Higher values will increase the
amount of signal that feeds Filter 2 and decrease the amount of signal that feeds Filter 1. If set to mid,
both filters will receive the same signal level. If set to F2 63, the signal is sent to Filter 2 only.
Osc3
Volume of Oscillator 3.
Osc3 Balance
Determines the ratio of the oscillator's signal that is sent to the inputs of Filter 1 and Filter 2 (see
routing picture). If set to F1 64, the signal is sent to Filter 1 only. Higher values will increase the
amount of signal that feeds Filter 2 and decrease the amount of signal that feeds Filter 1. If set to mid,
both filters will receive the same signal level. If set to F2 63, the signal is sent to Filter 2 only.
RingMod
Volume of the ring modulation between Oscillator 1 and 2. From a technical point of view ring
modulation is the multiplication of two oscillators' 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. Please note that in a complex
waveform all harmonic components behave like interacting sine waves, resulting in a wide spectral
range of the ring modulated sound. The following pictures show the results of a saw wave
ringmodulated with a square wave and two ringmodulated sine waves:

Picture 20: Ring Modulation of two Sine waves with different frequencies.
Ring Modulation can result in unwanted low frequencies when the pitches of oscillator 1 and 2
don't differ very much. This is logical because when you use i.e. one oscillator set to 100Hz
and the second set to 101Hz, the resulting ring modulation is 201Hz and 1Hz. And 1Hz is very
low.
