Maths SUM output adds or subtracts control signals using attenuvertor polarity

The SUM output on Maths sums all four channels’ contributions weighted by their Attenuvertors. For mixing: set Attenuvertors full CW for addition, full CCW for subtraction. When using CH.1 or 4 as summers (not as function generators), set RISE and FALL to full CCW and do not engage CYCLE — this prevents the channels from shaping the signal. CH.2 and 3 are permanently in through mode. This makes Maths a four-input CV mixer and offset generator in one.

Examples

To add CV_A and subtract CV_B: CH.1 Signal IN = CV_A, Attenuvertor full CW. CH.2 Signal IN = CV_B, Attenuvertor full CCW. CH.1 RISE+FALL full CCW, no CYCLE. Take SUM OUT.

Assessment

Describe the minimum configuration to use Maths as a three-input CV adder where one input is inverted, and state which parameter must be at zero to prevent shaping.
