Jolin Lab Krono Multi-Modal Programmable Clock Generator

The Jolin Labs Krono is a 4HP programmable multi-mode clock and rhythm generator module that features tap tempo, state persistence, CV group swap and 12 independent outputs.

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++), customisable.
• Programming: Via USB-C DFU.
• “whatever” power connector – don't mind the polarity, it's protected either way.
