Signal Outputs
There are many different signal outputs on the MATHS. All of them are situated at the bottom of the module. Many of them have
LEDs situated nearby for visual indication of the signals.
The Variable Outs
These outputs are labeled 1, 2, 3 and 4 and are associated with the four Attenuverter controls in the center of the module. These
outputs are all determined by the settings of their associated controls, esp. the CH. 1 through 4 Attenuverter controls. All of these
jacks are normalled to the SUM and OR Bus. With nothing patched to these outputs, the associated signal is injected into the SUM
and OR Bus. When you patch a cable into any one of these output jacks, the associated signal is removed from the SUM and OR
Bus. These outputs are useful when you have a modulation destination where there is no attenuation or inversion available (the
CV inputs on the MATHS or FUNCTION modules for example). They are also useful when you want to create a variation of signal
that is at a different amplitude or phase.
EOR OUT
This is the End Of Rise Output for CH. 1. This is an event signal. It is either at 0V or 10V and nothing between. It defaults to 0V, or
Low when there is no activity. The event in this case is when the associated Channel reaches the highest voltage to which it
travels. This is a good signal to choose for Clocking or Pulse shaped LFO. It is also useful for Pulse Delay and clock division since
the Rise sets the amount of time it takes for this output to go High.
EOC OUT
This is the End Of Cycle output for CH. 4. This is an event signal. It is either at 0V or 10V and nothing between. It defaults to +10V,
or High, when there is no activity. The event in this case is when the associated Channel reaches the lowest voltage to which it
travels. The associated LED is on when nothing is happening. This is a good signal to choose for Clocking or Pulse shaped LFO.
Unity Signal Outs, CH. 1 and 4
These outputs are tapped directly off the core of the associated Channel. They are not affected by the Channel's Attenuverter.
Patching into this output does NOT remove the signal from the SUM and OR Buses. This is a good output to use when you do not
require attenuation or inversion or when you want to use the signal both independently and within the SUM/OR Bus.
OR OUT
This is the output from the analog OR circuit. The inputs are CH. 1, 2, 3, and the 4 Variable Outputs. It always outputs the highest
voltage out of all the voltages applied to the inputs. Some people call this a Maximum Voltage selector circuit! The attenuators
allow for weighting the signals. It does not respond to negative voltages, therefore it could also be used to rectify a signal. Useful
for creating variations on a modulation or sending CV to inputs that only respond to positive voltages (e.g. Organize CV Input on
the PHONOGENE).
SUM OUT
This is the output from the analog SUM circuit. The inputs are CH. 1, 2, 3, and 4 Variable Outputs. Depending upon how the
Attenuverters are set, you could add, invert or subtract voltages from each other using this circuit. This is a good output to use for
combining several control signals in order to generate more complex modulations.
INV OUT
This is the inverted version of the SUM Output. It allows you to modulate backwards!
