I started with layout It has 40 Keys in 10 x 4 Layout.Top two layers are for High octave and bottom two for Low octave the three sliders are for Filter,Reverb,Modulation and three encoders are for Volume, Tempo, Track control.I used Matrix so it uses less Gpios, It is based on Raspberry Pico. PCB made in Kicad and modeling done in Fusion 360. Firmware is written in circuit python and uses Adafruit MIDI Library.

Questions
How big is the Pro Midi Controller PCB?
It measures 193 × 154.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pro Midi Controller use?
87 parts. 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 Pro Midi Controller KiCad files?
From the adirock09/MIDI- repository on GitHub, at the commit this page was made from: the board is MIDI Controller/PCB/Pro Midi Controller.kicad_pcb and its schematic MIDI Controller/PCB/Pro Midi Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pro Midi Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask adirock09 before reusing the design.
