The Doepfer Wheel Electronic is primarily designed to attach a MIDI-compatible modwheel into an instrument, however do not be limited by this concept! You can use everything from joysticks, footswitches or footpedals, photo resistors... ÿThe limits are only up to your imagination!


Wheel Electronic (abbreviation: "WE" in the following) is an universal electronics DIY Midi kit designed to connect modulation or pitch wheels. But it can be used also for joy sticks, single or multiple foot controllers (analog or on/off), breath controllers or even normal potentiometers. In addition a connector for a sustain foot switch is available.Up to 4 continuously variable "analog" elements and a "digital" switching element (e.g. a sustain foot switch) can be connected.

Application examples:

  • pitch bender
  • wheels
  • joy sticks
  • breath controllers (e.g. Yamaha BC-1/2/3, additional resistor required, please refer to the user's manual)
  • foot controllers (continuos)
  • foot switches (on/off), momentary or toggle
  • rotary potentiometers
  • slider/fader potentiometers

Different elements can be combined simultaneously. Here are some examples:

  • pitch bender, modulation wheel, volume control (rotary or slider potentiometer), breath controller and sustain foot switch
  • pitch bender, three modulation wheels (e.g. modulation, volume, after touch) and sustain foot switch
  • pitch bender, two modulation wheels (e.g. modulation and after touch), one rotary or slider potentiometer (volume) and sustain foot switch
  • pitch bender, modulation wheel and joy stick
  • two joy sticks
  • four foot controllers for volume control of four Midi channels
  • dual or tripe foot controller (on/off or analog) and rotary or slider potentiometer
  • two modulation wheels or switches to control the rotary speakers of the organ software B4 (von Native Instruments), two rotary or slider potentiometers for volume and expression
The four "analog" elements are connected to pinheaders with 3 pins. For the "digital" switching element a pinheader with 2 pins is available. The pin headers are the white parts in the above picture.
Four 3-pin cable sets and one 2-pin cable set about 30cm each with suitable female connectors are included (please refer to the pictures of the applications examples below).

WE has some special features compared to other Midi control electronics (e.g. Pocket Electronic):
  • The upper voltage that is assigned to the Midi data value 127 can be adjusted exactly with a multi-gang trimming potentiometer. This measure is necessary e.g. for modulation or pitch wheels, foot controllers or joy sticks that do not cover the complete angle of rotation. If such an element is connected to GND and +5V the maximal output voltage is much less than +5V (e.g. +3V only). Even breath controllers (e.g. Yamaha BC-1/2/3) output only about +3.5V maximal control voltage. If an electronics is used that analyses the full voltage range 0...+5V the higher Midi data values are missing.
  • The voltage range can be reduced with the trimming potentiometer to 0...+3V.
  • For each of the four elements a jumper is used to select if the full voltage range (0...+5V) or the adjustable voltage range is used for measurement. This is necessary if different elements are used simultaneously (e.g. modulation wheels or foot controller with reduced voltage range and normal rotary or slider potentiometers with full voltage range).
  • If an element is assigned to Midi pitch bend a "plateau" is used in the middle of the voltage/data range (data value 64). This feature is meaningful in combination with spring-loaded wheels or joy sticks as due to mechanical tolerances the exact center position is not always reached.
Four jumpers are used to select the Midi channel. 

Further four jumpers are used to select up to 16 different combinations of Midi control change numbers, pitch bend or after touch - the so-called presets.
Remark: Currently not yet all 16 presets are used. A detailed list of all available combinations can be found in the user's manual.
