don’t PM me for Maths.
I’m wondering what modules will straight up add control voltages together, or do other arithmetic.
Are there DIY options?
<3 <3 <3
almost every mathematical operation and published in 1966. It predated the linear multiplier which was a huge advance in the state of the art. Hinton ModMix has the best implementation of a linear multiplier circuit.
There’s a simple DIY utilities module available here that does some math functions (add, subtract, invert, etc):
adding control voltages together- isn’t that just a mixer?
some of my favorite CV processors that do adding, subtracting, mixing, attenuating, inverting, attenuverting, etc are intellijel triatt, happy nerding 3XMIA, and (of course) maths
The Doepfer 185-2 Precision Adder is a great tool for this. It will add or subtract 4 CVs together
Mutable Kinks has some math functions like Min, Max, Absolute Value (only positive values), >0
ALM’s Beast’s Chalkboard adds or subtracts whole volts to a signal to make octave or sub-octave CVs and then giving you the original buffered CV as well. It’s a pretty handy utility
Precision adder plus dividers plus a VCA which varies between exponential and linear.
