Logic Matrix With Quad Clock Divider
Triple Sample and Hold and gate-to-Trig
CEREBELLUM is a matrix for sequential Boolean logic operations. It can craft complex polyrhythms, arrange generative structures that evolve over the course of a piece of music, and even produce gnarly timbres when combining audio rate signals.
The module accepts inputs on three rows, which may be operated upon by signals from four columns before output. An operation is active when a latching 15mm LED switch is engaged at each node, which displays the new signal. A second switch allows a choice of AND or XOR operands.
To extend the module’s functionality, each column provides a clock divider and static +5V “on” and NOT invert switches. The dividers alternate between a binary counter /x^2 (2 through 128) and a decade counter /x (integers 2 through 8) paired with a LATCH flip-flop.
A single signal at IN ALL addresses all columns, which have outputs after their division and invert operations. All dividers receive individual resets and RST ALL. Columns 1, 2, and 3 are normalled to rows A, B, and C respectively, allowing the creation of seven inter-related signals from one input.
CEREBELLUM is 30 hp and 38mm deep.
DM is a stand-alone companion module that provides two useful extra functions: reducing gate patterns down to triggers, and using these to sample and hold external CV. This allows Cerebellum’s patterns to alter and extend existing voltage sequences.
Both the gate and signal inputs are normalled down the three separate circuits. Switches allow the choice of track or sample and hold.
DM is 4 hp and 38mm deep.
