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 two
ringmodulated sine waves:

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 100 Hz and the
second set to 101 Hz, the resulting ring modulation is
201 Hz and 1 Hz, and 1 Hz is very low.
[ Ring Modulation can be very interesting when a
slow pitch modulation is applied to one oscillator,
i.e. a decaying Envelope. This creates spacy effect
sounds.
[ For an E-Piano sound, you might apply Ring
Modulation when one high pitched oscillator’s
Keytrack
is lowered to i.e. 50%.
[ If you turn down the pitch of one oscillator
markedly, you can get an effect very similar to
Amplitude modulation. Use this for sounds with a
periodic element if you wish.
RingMod Balance F1 64...mid...F2 63
Determines the ratio of the ring modulator’s signal that is
sent to the inputs of Filter 1 and/or Filter 2. 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.
Noise
The following parameters refer to the noise generator.
Noise Level 0...127
Volume of the noise generator Noise is a fundamental
source for any kind of analog-type percussion. Also, wind.
A Sine wave with frequency 1 ringmodulated with a Sine wave with
frequency 2.5 (1 octave + 4 semitones)
results in this wave
