Highly Liquid Forum member Labelwhore used 3 MIDI CPUs to create an FL Studio controller with 8 slide pots, 16 buttons, and 24 rotary encoders. The controller is housed inside a Pactec KE-20 enclosure with custom panels laser cut and engraved by Ponoko.
All of the project details including parts list, MIDI CPU configuration files, Reaktor ensemble file and FL Studio dashboard file can be found in the excellent project article by Labelwhore. Additional discussion can be found in the project’s HL forum thread.
The MIDI CPU makes it easy to build a MIDI controller of any shape and size. This howto describes the process of building a wall-sized MIDI controller. The example project is the “Living Schematic” MIDI controller / exhibit.
Here are the basic steps:
Make a feature “wish list” for the MIDI controller.
“Budget” the MIDI CPU I/O.
Create a MIDI CPU wiring diagram.
Optional: Using a bit of artistic license, magnify & rearrange the wiring diagram to fit the wall.
Optional: Paint the oversize diagram on the wall.
Mount the controls.
Wire the controls to the MIDI CPU.
Configure the MIDI CPU to accept input from the controls.
Connect the sound module(s) to the new MIDI controller.
This zip file includes the parts list (Open Office .ods), design drawings (Corel Draw .cdr & .png) and MIDI SysEx files (.txt and binary .syx) used in the project. Discuss this howto at the forums.
The new MIDI CPU accepts input from switches, potentiometers, rotary encoders, switch matrices and external digital & analog signals. In response, it generates virtually any type of MIDI message. Buy now!
The MIDI CPU ships fully assembled. Simply attach MIDI connectors, control components, and a battery or DC power supply.
24 independent input terminals
Monitors up to 128 switches, 14 potentiometers, or 12 encoders
Allows mixed input types
Merges MIDI input with locally generated messages—multiple units share a single MIDI Out port
Powered via battery or DC supply between 3.3V and 12V
Measures only 66mm x 38mm (2.6″ x 1.5″)
Configured via MIDI SysEx message
The MIDI CPU has a long list of potential applications. Build your own traditional footswitch, keyboard, or “knob box” controller. Build your own alternative MIDI controller—optical theremin, fret-based controller, etc. Generate MIDI note patterns or CC waveforms from digital or analog signals. Re-purpose a “consumer” keyboard, calculator, game controller, or other electronic device as a MIDI controller.
These possibilities will be explored with “how-to” information at the blog and forums.
