PHOBOS - USER MANUAL
T H E C O N V O L U T I O N T R I A N G L E
At the centre of Phobos is the Convolution Triangle. Each Source
is represented on the Triangle by a ‘puck’ with the number of the
source sound on it. The placement of the puck on the Triangle
controls the level sent to each Convolver.
The top left of the triangle controls levels to controller W, the
top right X and the bottom W. So for an equal mix between the
three Convolvers, place the puck in the centre of the Triangle
(DOUBLE-CLICK on the puck). To have Source 1 processed
only by convolver W, place the ‘1’ puck in the top left corner
as illustrated.
The Keyboard Range section dictates which range on the keyboard triggers which Sources and Convolvers. With the range spread
across the whole keyboard, all Sources and Convolvers are triggered by the whole keyboard, but with interesting placements, you
can use the Sources as triggers for the Convolvers, or even separate different sounds onto different octaves.
1. SOURCE SOUNDS
These four lines represent the ranges of each of the four source
sounds 1,2,3,4.
2. CONVOLVERS
These three lines represent the ranges of each of the three
convolvers W,X,Y.
3. RANGE NODES
Grab these from the left and right end of the range to deter-
mine what source sound and convolver sits where.
4. KEY INDICATORS
These will light up when certain keys are being played. This key
is always shaded to illustrate middle C (C4).
5. KEY RANGES
These indicate exactly which ranges you’ve determined.
6 & 7. CONTROLLERS MOD & PITCH
Indicating and controlling modulation and pitch.
