The filter receives its signal from the following sound sources: Oscillator 1, Oscillator 2,
the noise generator and the ring modulator. Their output sections are displayed by four
objects that sit adjacent to the filter (three round objects and the smaller, rectangular
ring modulator to the right of the filter). One level down, you’ll find the control
elements for these sound sources.
On each of the objects that adjoins the filter you’ll find a small, red signal flow button
which indicates whether the signals should proceed through the filter or bypass it on
their way to the Output section of the synthesizer. Along the output path to the right,
the signals pass through two equalizers and a stage for stereo expansion or panoramic
modulation.
The output of the drum sound is then passed along to the mixer that is integrated into
the Assignment section (see “The Mixer” section, on page 352).
Common Parameters of Oscillators 1 and 2
To use Oscillator 1 or 2, you first need to turn them on. This can be done with the On/
Off button in the upper left corner of the Oscillator 1 or 2 section. When active, the
button is red.
Note: When programming a drum sound, you can turn the individual sound sources on
or off with the On/Off buttons. You can also listen to the individual components of the
sound separately this way, and remove them from the patch if necessary.
The volume of Oscillator 1 or 2 is controlled by the Volume knob shown on the right
edge of the Oscillator 1 or 2, respectively, sections. Volume can be modulated by the
sources found in the Mod and Via menus. For more information, see “Modulation” on
page 373.
The curved slider to the left of the Volume knob controls the pitch of the oscillators in
half step intervals. If you press Shift, you can adjust the pitch in cent intervals.
