Intellijel Plog Cheat Sheet
Plog is a flexible, voltage-controlled logic processor module with two 3-input logic blocks (A & B), a toggle flip-flop (T), and a data flip-flop (D). Useful for creating complex patterns, clock/trigger manipulation, and experimental generative sequences.
Panel Controls & Features
Logic Blocks (A & B)
- TYPE Button
- Press: Cycle logic type (AND, OR, NOR, XOR, NAND, XNOR) for selected block
-
Hold (1 sec): Load preset from memory
-
TYPE CV Attenuator (A & B)
-
Mini knobs to scale incoming CV to TYPE A/B CV inputs
-
SELECT Button
- Press: Select which logic block (A or B) to edit
-
Hold (1 sec): Save current logic states to memory
-
OUT A / OUT B (Outputs)
-
Main logic block outputs
-
TYPE A/B CV Input ([±5V], bipolar)
- Controls which logic type is selected for each block
- LEDs indicate selected logic type
-
Typical logic types per CV:
- AND, OR, NOR, XOR, NAND, XNOR
-
X, Y, Z Inputs (Channel A & B, [0-5V logic], protected ± overvoltage)
- X and Y of A are normalled to X and Y of B
- Z is normalled to Y unless patched
- 0V = logic LOW; 5V = logic HIGH; comparator threshold ≈3V
Flip-Flop Section
- TRIGGER Button
- Press: Sends trigger to Toggle input (T Flip-Flop)
-
Hold (1 sec): Enter tap-tempo mode, tap to set clock, hold again to exit
-
TOGGLE Input (T, [0-5V logic], protected)
- Trigger for Toggle flip-flop
- TRIGGER button normalled to this jack
-
Jumper on back: can normal OUT B here
-
OUT T (Output, [0-5V pulses])
- Output of the Toggle flip-flop
-
In tap-tempo mode: tempo clock output (square pulses)
-
CLK (Clock Input, [0-5V logic])
- Clock input for Data (D) flip-flop
-
OUT T normalled to here
-
DATA (Input, [0-5V logic])
-
Data input for Data (D) flip-flop
-
OUT D (Output, [0-5V pulses])
- Output of the Data flip-flop
Logic Types and Truth Tables
| Logic Type |
Description |
| AND |
High only if all inputs are High |
| OR |
High if any input is High |
| NOR |
High if all inputs are Low |
| XOR |
High if odd number of inputs are High |
| NAND |
High unless all inputs are High |
| XNOR |
High if even number of inputs are High |
See manual Tables 1 & 2 for detailed truth tables for 3 or 2 input modes.
Usage Ideas
- Clock Dividing: Use the flip-flops as /2, /4 clock dividers
- Randomized Triggers: Patch random and quantized sources into logic blocks for "real-time quantizer" effects
- Pattern Mutation: Use CV over logic type inputs to morph gate patterns
- CV Addressed Logic: Modulate TYPE A/B CV for evolving logic operations
Voltage Ranges
- Logic inputs: 0-5V pulses/gates/clocks (comparator @ 3V threshold, accepts non-square inputs)
- CV TYPE inputs: ±5V (bipolar, for logic type selection)
- Outputs: 0-5V (unipolar pulses/gates/clocks)
Technical Specs (from manual)
- 8HP, 29mm depth
- +12V 55mA / -12V 11mA
Example Patch (Quantized LFO)
- Set A to AND
- Random triggers (e.g. square LFO) → X
- Clock (e.g. drum machine/sequencer) → Y
- OUT A → Envelope → VCA
- Modulate TYPE A CV for extra variation
