ELECTROBOX for the Nord Electro 5/6

Arduino and the development of ElectroBox

I already had experience of Arduino when I built a drawbar controller to use with Hammond apps like VB-3 and B-3x. The original code for this came from GMLabs D9U project and Guido Scognamiglio posted all the info on GitHub:

I have implemented an LFO which cyclically adds or subtracts values from the Pitch Bend data. This is basically a software generated triangle wave LFO that is added to the Pitch Bend output. Crude but effective. The LFO is generated from a wavetable so it would very easy to have a number of different waveforms such as square or saw. The pots are programmable and there is an input for an expression pedal.

ElectroBox V2 - joystick version

Thumbwheel/Joystick version housed in a stompbox enclosure

Feature list:
  • Joystick X-axis for Pitch Bend +/- 2 semitones
  • Joystick Y-+ve axis for Modulation (vibrato)
  • Assignable control of one parameter on the Nord using the Y -ve axis of the stick
  • Assignable control retained in memory
  • Triangle wave LFO with rate control
  • Mono/Poly switch - with last note retrigger in Mono Mode
  • Split switch - freely split Internal/External zones on the fly
  • Flip Split switch - sets external to lower and internal to upper
  • Program Advance input - requires a foot switch
  • Bypass switch - bypasses all functions except Program Advance
  • MIDI in/out on 5pin DIN 
  • Extra MIDI out for external synths
  • Extra channel can be set from 1-16 and is stored in memory
  • Control knobs for CC71 (res) and CC74 (cut off)
  • USB powered
  • High quality aluminium stomp box style enclosure
  • Original Nord knobs 

Note the 2 rotary pots for additional control


I picked up a Roland bender on eBay last week. I always preferred the bender for performance despite being less versatile than 2 wheels. I tried to fit into the PW box but there wasn't space.

So.... thinking outside the box!

At some point I will rehouse it in a proper enclosure.
