| T he heart of the crusher: Vapor-Modulations
About the Vapor-Modulations | After selecting an input for the crusher using the Sampler or DCO panels and the mixer you can control the crusher options by using the faders or fields in this panel. In the joystick dialog you can choose witch parameter should be mirrored at the force feedback device and let your hands shake! All crusher panels share the same structure. All parameters apply to all of the specified grain generators. Changes between single generators can only be made by using the Gen. Phase fader. The Offset fader sets the general offset of the parameter defined in the left upper corner of the panel (Here it is Delay). Depth defines the modulation depth of the panel's oscillator. The modulation depth never exceeds the range of the Offset value. So if you set Offset to 10 and Depth to 100 the modulation's range is from 10 to 110. Speed determines the frequency of the modulation. Mode sets the oscillator mode. Many LFO types are available. Use X UpManual, X DnManual, Off, etc. to assign the modulator. Manual allows you to modulate with the Manuals or the Joystick. Off means that the modulator is fixed to the neutral 50% value. OffUp assigns a fixed 0% value and OffDn assigns the value to 100%. Each modulation is passed through a logarithm to exponent processing. You can adjust the processing curve with the log-lin-exp fader. The little graph will show you the resulting processing. In combination with the modulations sources this function is very usefull to generate more "human" modulations. Use the Cloud fader for additional modulation. This general modulator can be configured and controlled from the panel of the Cloud Oscillator. To define the fader range, slide the small buttons above the faders. Use the Gen. Phase fader to define a change of the modulation phase between the individual generators. For a visual example, look at the Cloud 3D window while running the crusher and change the parameters!
D elay/Length/Pause | The Delay panel defines the offset and the modulation of the delay between the sound input into the buffer and the grain(s) output. Length determines the length of the grain and Pause sets the pause between the generated grains. All values are specified in samples not in seconds. In the Cloud 3D window the grains are represented by the rectangles in the 3D field. The Delay is shown in the z-axis and the Pause is shown in the x-axis. The y-axis shows the different Generators.
Speed/Direction | Speed refers to the pitch of the grain. It is defined in percentage and ranges from 1% (1/100 pitch) to 200% (double pitch). No sample rate conversions are made so that you hear up- and down-sampling errors. This is what makes the crusher so aggressive! Direction determines whether the grain is played forward or backwards. Use this for longer grains (increase the Length) to make senseless speech sounds! In the Cloud 3D window the Speed is represented by the color of the grain: blue means 1%, white means 200%, and red is the 100% neutral color. The Direction is shown by a triangle in the middle of the grain.
F ilter | Each Generator has its own IIR-Filter that can be set up by its Frequency and by its Bandwidth Q. The Filter Mode is defined in the Vapor-Settings panel. If the Filter Mode is ByPass changes in Filter Freq. and Filter Q. will not affect the sound. In the Cloud 3D window the filter's frequency is represented by the brightness of the grain. The Bandwidth Q is represented by the brightness of a horizontal line. A bright line means a high Q and narrower Bandwidth.
Volume/Pan | Each grain can be modulated in Volume and Pan. Experiment with the Phase fader in the Pan panel and you can create a strange stereo panorama! Note: The crusher buffer is only mono, but during grain generation, crusher-X sends a mix to the output stereo bus. In the Cloud 3D window Volume is represented by the height of the grain. During panning, the sides of the grain are pulled down.
