Expert Sleepers Silent Way v2.4.3 - Manual (Page 79)

The seven controls per row are as follows:
Offset
This is simply a constant offset. You might use it, for example, to set the centre frequency
of a filter around which the other signals modulate.
Note
The Note output derives from the current pitch that is sounding, via the calibration profile.
Gate
The gate output is simply on or off, depending on whether the voice/touch is active. You
might use this to drive a hardware envelope generator.
X
The raw ‘x’ position (left to right) of the touch.
Y
The raw ‘y’ position (bottom to top) of the touch.
Z
The raw ‘z’ position (pressure) of the touch.
Smooth
The ‘Smth’ control has the same effect as that in the DC plug-in (see above ).
