1. DECAY Slider
This adjusts the decay time. From very short, highly damped clicks/taps all the way to events ringing
several seconds in duration. Offset control.
2. OPEN Slider
This slider is used to manually open the gate. This offset is post EG. Offset control.
3. DECAY Trimmer
Attenuverter trimmer for the DECAY CV input. 12 o'clock sets gain = 0, full CW sets gain = 1, and full
CCW sets gain = -1 (inverted). NOTE: unlike the CTRL input, there is no normalisation to DC at the
DECAY jack therefore this trimmer is only used when a signal is applied to the DECAY input jack.
4. MATERIAL Switch
The MATERIAL switch selects one of three material characteristics and controls how the gate
responds to a hit or control events. Up responds like the hardest of materials with lots of brightness
and very fast attack. Middle is the softest material with the slowest attack, more muffling, and lower
volume. Down is a balance between these two materials.
5. Openness Indicator
This indicator displays how open the Gate is.
6. DECAY Input Jack
This input allows for external voltage control over the decay time. It is summed with the DECAY slider
setting which means the DECAY control will be the pivot point. Negative levels will subtract from the
DECAY slider setting and positive levels will add to the DECAY slider setting.
7. CTRL Trimmer
Attenuverter trimmer for the CTRL input. 12 o'clock sets gain = 0, full CW sets gain = 1, and full CCW
sets gain = -1 (inverted).
The CTRL jack has 10VDC normalled to it so it will be a second offset (along with OPEN) but this
signal is pre-EG. Besides being pre-EG, it also also allowed to go below the minimum closure set by
OPEN. At noon, the voltage added is 0V. You can zero this using the CTRL Zero Indicator, if desired.
See the 'OPEN, CTRL, and DECAY Relationships' and 'From Within the Gate' sections for detail on how
CTRL and OPEN are related and why we decided on this implementation.
