DESCRIPTION
Want to build your own drawbar MIDI controller?
This complete kit is ideal for DIY projects and includes 9 organ drawbars, MIDI output, and pedal inputs for swell (expression pedal) and rotary speed (sustain pedal). It offers ample analog and digital inputs for adding your own potentiometers and switches.

The kit comes pre-assembled and ready to use—just mount it in an enclosure and add the switches and potentiometers of your choice (sold separately).

Electronics are based on an Arduino (Atmel 328P chip) and can be programmed using the Arduino IDE via the ISP pins. The kit can also be delivered pre-programmed to work with Nord Stage, Acoustic Samples B-5, GSI VB3, or Hammond B3-X at no extra cost.
The Arduino code is included, so you can easily customize it if you add more controls later.

SPECIFICATIONS

• 9 drawbars (10K linear potentiometers)

• 2 pedal inputs:
  – 1 digital (on/off for rotary speed)
  – 1 analog (for 10K expression/volume pedal)

• 5-pin MIDI OUT socket

• 9V DC power input (9V 1A, center positive)

• 19 digital inputs for on/off switches (2-pin XH connectors: GND + signal)

• 11 analog inputs for potentiometers (3-pin XH connectors: 5V + GND + signal)

• 8-pin XH connector for optional analog multiplexer (e.g., to add a second set of drawbars or more potentiometers)

• 1 XH connector for additional GND

• 1 XH connector for red LED power indicator

• 1 XH connector for power switch

DIMENSIONS

• Width: 155 mm

• Length: 130 mm (front to back)

• Height: 45 mm

Note: Dimensions refer to the circuit board only (excluding drawbars). These should be considered when designing the internal space of your enclosure.
