Percussion Oscillator

This is an oscillator that generates percussive sounds. The amplitude and pitch of the sound can be modulated from external sources.

Amp Input
A signal at this audio input modulates the amplitude of the sound. The attenuation is fixed at a 1:1 ratio.

Trig Input

Use this input to trig the sound. Any signal that increases from 0 units or less, to anything above 0 units will trig the sound. The red color of the input indicates that it also accepts full audio frequency signals.

Click

With the Click knob you can add a clicking sound to the attack of the sound.

Decay

Sets the decay time of the sound.

Display Box

Click on the display box to switch between notes and Hz. Range: C-1 to G9 (7.94 Hz to 12910 Hz).

Pitch

Sets the coarse pitch of the oscillator. Range: C-1 to G9 (8.18 Hz to 12540 Hz).

Fine

Sets the fine tuning of the oscillator. The range is +/- half a semitone divided into 128 steps. Click on the triangle above the control to reset the fine tuning to 0, which is the preset value.

Pitch Modulation Input [a attenuator Type II]

There is a blue modulation input for modulating the oscillator pitch on this module. The modulation amount is attenuated with the rotary knob next to the input. See Pitch modulation on page 34 for more info.

Punch

Changes the characteristics of the sound and adds a more distinct attack.

M

Click on this button to mute the audio output of the oscillator.

Out

Signal: Bipolar.
