About this Gig
I will engineer a custom MIDI controller PCB with modular RGB buttons, rotary encoders, faders, and USB firmware fully production ready. I specialize in USB MIDI class compliant hardware, multilayer PCB layout, and embedded firmware for Arduino, STM32, and ATmega32U4. Whether you need a DAW controller, pad grid, or studio performance device, I deliver clean schematics, DRC checked Gerbers, BOM, plug & play USB firmware
What I Offer:
- Custom MIDI controller schematic (USB & DIN MIDI)
- Modular multilayer PCB layout (RGB buttons, faders, encoders)
- USB MIDI class-compliant firmware (no drivers needed)
- RGB LED integration (WS2812B / NeoPixel)
- Encoder, fader & potentiometer hardware mapping
- Manufacturer-ready Gerber & drill files
- Bill of Materials (BOM) with sourcing references
- Pick & Place file for SMD assembly
- Design Rule Check (DRC) error free guaranteed
- Schematic PDF, firmware guide & assembly notes
Why Choose Me
- Custom MIDI hardware, USB firmware & PCB engineering specialist
- Modular, scalable layouts optimized for RGB, faders & live performance
- Gerber files compatible with JLCPCB, PCBWay & all major manufacturers

FAQ
Will the MIDI controller work plug-and-play with Ableton or FL Studio?
Yes. I develop USB MIDI class compliant firmware so your controller is instantly recognized by Ableton Live, FL Studio, Logic Pro, and any DAW no drivers needed. DIN MIDI output for hardware synths is also available on request.
What microcontrollers do you use for the USB MIDI firmware?
I work with ATmega32U4 (Arduino Pro Micro), STM32, and ESP32 depending on your project needs. ATmega32U4 and STM32 are ideal for native USB MIDI, while ESP32 supports both USB and wireless BLE MIDI for advanced setups.
Can the RGB LEDs respond to incoming MIDI signals or DAW feedback?
Yes. RGB LEDs (WS2812B or NeoPixel) are fully integrated into the firmware and can respond to note on/off events, velocity, CC values, or DAW visual feedback giving your controller real time reactive lighting during performance.
Can you make the controller modular so I can add more pads or faders later?
Absolutely. I engineer modular PCB sections that expand via I2C, SPI, or UART allowing you to add pad, fader, or encoder modules to a master board at any time. Each module is independently addressable and managed by the central MIDI firmware.
What files will I receive at the end of the project?
You receive Gerber & drill files, BOM, Pick & Place file, full schematic PDF, editable PCB source files, compiled firmware with source code, and an assembly guide everything needed to order your PCB and assemble your MIDI controller immediately.
