Granulator is a real-time, MIDI controllable, granular synthesizer.
Granular synthesizers generate thousands of very short sonic grains to create audio textures.
What are the parameters of Granulator ?
- density: number of grains by time frame
- duration: duration of the grain
For high density and duration values, over one hundred grains can be playing at the same time. Playing over 100 voices simultaneously requires a lot of CPU resources. The CPU load is displayed as a percentage in the title bar of Granulator's window. This value is refreshed every second.
- pitch: pitch of the grain
- offset: the starting point of the grain in the waveform
- waveform: to select a new waveform, double-click on the graphic.
- cutoff: cutoff frequency of the filter
- resonance: resonance of the filter
This is a low pass filter with a 24dB/octave slope.
- attack: the attack time of the envelope
- release: the release time of the envelope
To speed up the calculations, the envelope is trapezoidal. Although it would be nice to have other envelope shapes, this is usually sufficient for granular synthesis. If the attack and release parameters are both set to 0 the envelope has the shape of a pulse. If the attack and release parameters are both set to 127, the envelope has a triangular shape.
- amplitude: amplitude of the grains
- pan: position of the grains in the stereo field
- length: the duration of the delay
- feedback: the feedback of the delay
