r beny created a custom unit, Ultraviolet, for the Orthagonal Devices ER-301 Sound Computer that’s inspired by the Mutable Instruments Clouds module.

Here is a list of the parameters and what they do (everything can be put under CV-control):

Wet/Dry – Sets the wet/dry mix between the input source and the granular unit

In Gain – Sets the amount of the input signal feeding into the recording buffer/granular unit

Freeze – Gate input, stops the recording buffer from recording

Trigger – Trigger input, triggers the grains

Reverse – Toggle input, reverses the grains

Density – Triggers the grains internally without the need for a trigger input

Position – Sets the start point for the grains

Size – Sets the size of the grains

Cut – Cutoff of the filters

Res – Resonance of the filters

Pass – “Spread” of the filters

V/Oct – Volt per octave pitch control of the grains

Warble – Adds a small amount of pitch warble to the grains. Has a chorus effect when you can still hear the dry signal

Spread – Stereo spread and panning amount of the grains

Mod – Adds internal random modulation to the Position and Size parameters that are synced to both the Trigger Input and the Density Input

Gain – Grain gain

There are two versions of Ultraviolet – one has a feedback control which feeds the grains back into manual grain unit. The other has a control called Refract that is a distortion/bit crushing unit.

Ultraviolet is available as a free download. If you’ve used the mod, leave a comment and share your thoughts on it.
