A rudimentary step sequencer based on a Teensy 4.1 and a Novation Launchpad. It is mainly intended as a "jamming partner", not a full-fledged production tool.
Some basic features/specs:
-
7 Tracks. Can be set to output midi on serial, device or host ports
-
8 Patterns per track currently, but lots of room for expansion
-
64 Scenes, i.e combination of patterns
-
Patterns are edited on the Launchpad. Works during playing
-
Patterns can be set to any length between 1 and 128 steps
-
Patterns have configurable speed
-
Patterns and other settings stored on SD card
Component list:
- Teensy 4.1
- SD card
- ILI9341 display (touch is not used atm)
- 2 encoders
- 8 buttons via an MPC23017 expander
- Powered usb hub
- Novation Launchpad Mini Mk3

Questions
How big is the MidiSplitter PCB?
It measures 48.3 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MidiSplitter use?
21 parts, built around the 74HC14. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MidiSplitter KiCad files?
From the canvasus/Beatmaster2k repository on GitHub, at the commit this page was made from: the board is pcb/midiSplitter/midiSplitter/midiSplitter.kicad_pcb and its schematic pcb/midiSplitter/midiSplitter/midiSplitter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MidiSplitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask canvasus before reusing the design.
