4HP eurorack module that provides two trigger outputs with an adjustable rhythm based on the incoming MIDI timing clock.
MIDI clock (24 PPQN) is read from TRS type A input. MIDI start message resets all clocks.
Adjust output clock rate using the clock divider encoder. Turn it clockwise to decrease the rate and counterclockwise to increase it. Press and hold while turning the knob to set the second clock divider.
Clock outputs provide about 3 milliseconds triggers.
See BOM and board layout.
Schematic and PCB files are in the hardware KiCad project folder, which also contains panel design FreeCad file.
Project is built using make in debug mode by default. In order to change mode use make ENV=release build. The same applies to other Makefile variables. Available targets are
build- compile firmware.elf filesize- display firmware size in bytesfuses- program chip fuses bitsupload- write firmware to chip memory
In release mode reset is disabled (RSTDISBL fuse is programmed) due to lack of available pins.
- offset control (half of the note duration)
- triplet/dotted note switch
- MIDI type A/B switch
- gate length control (trigger or note duration)
- customizable dividers
