Plog rev 1.0 MANUAL

The Intellijel Plog is a voltage controllable digital logic

device designed for musical applications. It is primar-

ily intended to create controllable patterns from gate/

pulse sources like clocks and sequencers.

It has many other applications other than to simply

mutate drum patterns. What you will use it for is up to

your imagination!

It contains four major blocks of logical operations.

These blocks are normalled in such a way that all the

blocks can be used together with minimal patching.

The Plog comprises two - triple input boolean logic

sections (with CV over type), a toggle ip op and a

data ip op.

The Toggle ip op can also be turned into a tap

tempo clock source.

The normals of the Plog can all be broken via the

switching jacks or in the case of theToggle input by a

jumper on the rear panel.

The Plog has been realized with a micro controller

that allows us to have features such as CV over logic

type and memory recall of initial logic state. The digi-

tal design of the Plog also means it is very shallow

behind the panel.

Plog rev 1.0 MANUAL Front Panel 1 - TYPE (LOAD) This button selects the logic type for the selected channel, A or B. It also acts as the starting point when under CV control. Press and hold this button for one second to load the stored preset from memory. 2 - These two mini knobs attenuate the CV coming into their respective CV inputs labeled Type A and Type B. 3 - Type A/B bipolar CV input for logic type of channel A/B. You will see the logic type LEDs move when CV is present and SELECT is on A/B.

Plog rev 1.0 MANUAL Front Panel - cont’d A - TOGGLE input to the toggle flip flop. The TRIGGER button is normalled to this input with a switching jack. NOTE: There is a jumper on the back of the Plog module that connects the output of logic B to the normalled input of T. B - OUT T this is the output of the toggle flip-flop. If in tap tempo mode this becomes the tempo clock output (unipolar square pulses) C - CLK clock input to the data flip-flop. OUT T is normalled to here with a switching jack.

Plog rev 1.0 MANUAL Data (D) Flip-flop The D Flip-flop output latches to whatever logic level the input is but only when the CLK signal transitions from low to high. The CLK input is also normalled (via the switching jack) the inverted output of the D Flipflop. This causes the D FlipFlop to function as a T Flip-flop if nothing is patched into the CLK input. The following diagram illustrates the relationship between the D Flip-flop inputs and output.

Plog rev 1.0 MANUAL Example Patches Example # 1: Real-time Quantizer Using AND Logic Set A to AND and patch a random source of triggers into X. Then patch a quantized source of triggers into Y. Patch OUT A into a envelope generator. Patch the envelope generator into something you want to modulate with quantized random envelopes such as a VCA. Using AND logic on a random source of triggers such as a square wave LFO.
