Working on schematics.. _Please assist if you have the time and skills!_

My devices running it (nicknamed "Hensel MODEL-01") have the following features:

- High-precision Master Clock

	- MIDI Clock Output

	- CV/Gate Output (0V/5V)

- Micro-adjustable Tempo (endless rotary knob, two speeds)

- Tap-Tempo Function (dropout protection, auto-smoothing)

- Control MIDI Equipment (start, continue, stop)

- Settings can be saved in non-volatile memory

- Jumbo Tri-Color LEDs for Tempo and Status display

- MIDI-Thru (latency-free hardware circuit)

- Tolerant power input (7-12V DC) and hardware power switch

	- Low-power design, runs on batteries and USB-power (adapter required)

	- Energy-efficient power supply included
