Reddit User Transforms Keyboard into MIDI Controller
Reddit user u/xpercipio ingeniously converted an old PC keyboard into a fully functional USB-powered MIDI controller. This DIY project is compatible with both macOS and Windows operating systems.
The xp120 MIDI Controller
The custom-built MIDI controller, dubbed ‘xp120,’ boasts 120 keyboard switches arranged in a unique 12×10 grid. This layout allows for intuitive note activation.
Design and Functionality
Each switch triggers a specific note, with rows color-coded in black and white for easy identification. The first column represents the note C, followed by C#. The adjacent white columns denote E and F, respectively.
Technical Specifications and Performance
The video showcases u/xpercipio playing “The Maverick” from Native Instruments using the MIDI controller. The performance demonstrates a randomized velocity range between 70 and 80. The controller uses Cherry MX clear switches, known for their tactile feedback, which u/xpercipio finds pleasant.
u/xpercipio notes that the teensy-powered MIDI board’s stronger springs give them a linear feel, a personal preference despite the inherent tactile qualities of the switches.
