"Krono is a Multi-modal Programmable Clock Generator by Jolin.
With various modes, ranging from clock divider and multiplier to probabilistic, Euclidean, and chaotic modes it covers all the clock generation needs of modern eurorack."
KRONO is a 4HP programmable multi-mode clock and rhythm generator module featuring tap tempo, state persistence, CV group swap and 12 independent outputs.
Modes – firmware v1.0
1. Ratios: Direct multiplications and divisions of the base tempo for proportional rhythmic ratios.
2. Euclidean: Generates Euclidean rhythms by distributing K pulses over N steps.
3. Musical: Applies common musical ratios (e.g., triplets, dotted notes, predefined swing divisions).
4. Probabilistic: Outputs trigger based on defined probability thresholds for each output.
5. Sequential: Generates clocks based on mathematical sequences (Fibonacci, prime numbers).
6. Swing: Applies individual swing/shuffle levels per output, delaying even beats.
7. Polyrhythm: Assigns independent X:Y ratios to outputs; output 6 can generate a logical sum.
8. Logic: Applies logic operations (AND, OR, XOR, NAND, XNOR) between internal clocks or external inputs (if configured).
9. Phasing: Generates pulses with configurable time offsets (phase shifts) relative to the main clock.
10. Chaos: Creates unpredictable rhythmic patterns based on chaotic algorithms.
New modes will be added with upcoming firmware updates."
Features
12 Clock OutputS divided into two groups (A/B)
10 Operational Modes covering standard, mathematical, musical, probabilistic, and chaotic rhythms.
Weighted Tap Tempo & External Sync
State Persistence: Saves Tempo, Active Mode, and Swap State for each mode, retaining them across power cycles.
Calculation Swap: Inverts functions between groups via the MOD button or external gate.
Visual Feedback: the Status LED indicates the active mode; the Auxiliary LED signals state changes (tap, mode select, swap).
Fixed Base Clock Outputs: Outputs 1A and 1B always provide the unmodified main clock.
Hardware Platform: Based on CPU STM32F411.
Open Source: Firmware developed with PlatformIO (C/C++), customizable.
Programming: Via USB-C DFU.
“whatever” power connector – don’t mind the polarity, it’s protected eighter way.
