If the sum of all mixer signals (Osc 1, Osc 2 and Ring Modulator) is higher than
100%, filter saturation will be attained. At this point Resonance doesn´t make any
volume difference, as it does in the normal filtering process. Use this phenome-
non for additional sound manipulation.
Env (Envelope)
-100%...100%
This controls the influence of Envelope 1 or 2 on the Oscillator 2 level. With positive
settings, the level is increased by the modulation of the envelope, and with negative
settings, the level is decreased. Use this parameter to change the volume of Oscillator 2
independently over time.
Vel (Velocity)
-100%...100%
Determines the amount of influence the selected envelope has on level of Oscillator 2,
based on key velocity. This parameter works similarly to the
Env
parameter, with the
difference that its intensity is velocity based. When you hit the keys smoothly, the level
of Oscillator 2 only rises minimally. When you hit harder, the level will rise higher.
The overall modulation applied to Oscillator 2 level is calculated as the sum of both
the
Env
and
Vel
parameters. Therefore you should always bear this total in mind,
especially when the level does not behave as you expect. You can also create inte-
resting effects by setting one parameter to a positive and the other to a negative a-
mount.
Rmod (Ring Modulation)
0%...100%
Volume of the ring modulation between Oscillators 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 fre-
quency components. Since ring modulation generates disharmonic components, it can
be used to add metallic distorted sound characteristics. This is useful when generating
crashes or cowbells. Please note that in a complex waveform all harmonic components
behave like interacting sine waves, resulting in a wide spectral range of the ring modu-
lated sound.
Ring modulation can result in unwanted low frequencies when the pitches of Oscilla-
tors 1 and 2 don’t differ very much. This is logical because, for example, when you use
one oscillator set to 100 Hz and the second set to 101 Hz, the resulting ring modulati-
on is 201 Hz and 1 Hz, and 1 Hz is very low.
Crack
0%...100%
Fades in the Crack Modulator. The Crack Modulator was designed
especially for creating hand clap sounds. Technically it is an amplitude
modulation using a sawtooth waveform. The speed and the number of
waveforms can be chosen. After transmitting its intended modulation,
