About this Gig
I will engineer a custom modular MIDI controller PCB with RGB buttons, faders, encoders, and full firmware production ready for JLCPCB and PCBWay. I specialize in USB & DIN MIDI hardware, multilayer PCB layout, and enclosure integration. From DAW controllers to pad grids, I deliver DRC checked Gerbers, BOM, firmware, and enclosure files plug and play ready.
What I Offer:
- Custom MIDI controller schematic capture (USB & DIN MIDI)
- Multilayer PCB layout with RGB button matrix & fader routing
- Firmware development (Arduino, STM32, or ATmega32U4)
- RGB LED integration (WS2812B, NeoPixel, or discrete LEDs)
- Encoder, fader & potentiometer hardware mapping
- Manufacturer-ready Gerber & drill files (JLCPCB / PCBWay)
- Bill of Materials (BOM) with sourcing references
- Enclosure mechanical files (DXF / 3D model for laser cut or 3D print)
- Full documentation schematic PDF, firmware guide & assembly notes
Why Choose Me
- Custom MIDI hardware & embedded firmware specialist
- End to end PCB, firmware & enclosure in one package
- Clean layouts optimized for RGB & live performance
- Compatible with JLCPCB, PCBWay & major manufacturers

FAQ
What microcontrollers do you use for the MIDI firmware?
I work with ATmega32U4 (Arduino Leonardo/Pro Micro), STM32 (Bluepill/Nucleo), and ESP32 depending on your requirements. For USB MIDI class compliant devices, ATmega32U4 and STM32 are ideal. For wireless or advanced control, ESP32 with BLE MIDI is also available.
Can you integrate RGB LEDs that respond to MIDI signals?
Yes. I integrate WS2812B, NeoPixel, or discrete RGB LEDs into both the PCB layout and firmware. LEDs can respond to note on/off, velocity, CC values, or custom logic fully programmable to match your performance or visual feedback requirements.
Will the MIDI controller work plug and play with DAWs like Ableton or FL Studio?
Yes. I develop USB MIDI class compliant firmware so your controller is recognized instantly by Ableton Live, FL Studio, Logic Pro, and any DAW that supports standard MIDI no drivers needed. DIN MIDI output for hardware synths is also available on request.
Do you provide enclosure files for 3D printing or laser cutting?
Yes. The Premium package includes enclosure mechanical files in DXF format for laser cutting or STEP/STL for 3D printing. Enclosures are dimensioned to match your PCB layout precisely, with cutouts for buttons, faders, USB port, and mounting holes.
Can you build a modular MIDI controller that expands with additional units?
Absolutely. I can engineer modular PCB sections that daisy chain via I2C, SPI, or UART, allowing you to expand your controller by adding pad, fader, or encoder modules. Each module communicates with a central master board running the main MIDI firmware.
