Schlappi Engineering BTMX Four Bit Logic Mixer (Silver)

BTMX (BitMix) gives hands on control over logic and rhythmic gate signals with a switch for every input and 4 different logic functions.

It is a 4 channel selectable logic function module, with each channel having two inputs. All channels share the same logic function and the gate outs are summed with binary weights to create a stepped voltage to generate melodic or modulation signals from the outputs.

It pairs well with the Nibbler, other 4 bit logic modules, or any modules that generates sates (such as clock dividers and sequencers) and can also be used at audio rates.
