GRAIN SAMPLE MANIPULATOR768
The Oscillator section
The Oscillator can be used in addition to the sample playback. The oscillator features a number of selectable wave-
forms and a modulation control, which affect the signals differently depending on selected waveform. The oscillator
pitch always tracks the keyboard to 100%. This makes it perfect as a pitch reference for the sample signal.
On/Off
D Click the On/Off LED button to switch on/off the oscillator.
Oct
D Turn the OCT knob to change the pitch in octave steps.
Range: 5 octaves.
Waveform and Mod
D Select the desired waveform by dragging up/down in the waveform display, or by clicking the up/down but-
tons.
The waveforms are:
•Sine
A pure sinewave at Mod=0%, gradually transformed towards a sawtooth type signal at Mod=100%.
•Triangle
A triangle wave at Mod=0%, gradually transformed towards a sawtooth type signal at Mod=100%.
•Sawtooth
A lowpass-filtered sawtooth wave at Mod=0%, gradually transformed to a pure sawtooth signal at Mod=100%.
•Square/Pulse
A 50% duty cycle square wave at Mod=0%, gradually pulsewidth-modulated to a 0% duty cycle pulse wave
(silence) at Mod=100%.
q Modulate the Mod parameter from an LFO (using the Modulation Bus) to achieve PWM.
•Noise
A level-compensated lowpass-filtered noise at Mod=0%, gradually transformed to white noise at Mod=100%.
•Band Noise
A noise-modulated sinewave. The Mod knob controls noise bandwidth. At Mod=100%, the oscillator produces
pure noise. Turning the knob counter-clockwise towards 0% gradually narrows the noise bandwidth until a slightly
modulated sinewave is produced.
