Build your own MIDI instruments. Easy as pie, impressive on stage.


MidiMidi + MaKey MaKey = Your own MIDI controller without soldering.

Have you ever dreamed about building your own MIDI controller / drumkit / instrument but weren't sure about all the technical stuff? With MidiMidi (software) and MaKey MaKey (hardware) it's entirely possible to build your own gear within minutes - and without any soldering. If you know how to plug in a USB device you are ready to go.

How does it work?

MidiMidi (software) and the Kickstarter funded hardware MaKey MaKey are the dream team to build or prototype DIY MIDI instruments the easy way.

MaKey MaKey connects physical objects to your computer:
"Alligator Clip two objects to the MaKey MaKey board. For example, you and a banana. When you touch the banana, you make a connection, and MaKey MaKey sends the computer a keyboard message. The computer just thinks MaKey MaKey is a regular keyboard (or mouse)." (Quote from


But how can these key presses be used for making music? This is where MidiMidi comes into play! MidiMidi converts the keyboard messages into MIDI notes or MIDI controller data.
MidiMidi supports the same "keys" as MaKey MaKey out of the box (MaKey MaKey doesn't support the whole character set of a standard keyboard, it can only generate these keys: W, A, S, D, F, G, left, right, up, down, space). Just start the software and assign different MIDI events to them.

This is all it takes to build your first own controller!

Turns keyboard keys into notes

Supported Types of MIDI Data

MIDI Continuous Controllers

Set a channel and a controller (CC) number per key.
Define separate CC values for key press and key release events.
Activate the toggle mode to hold down the pad until you press the key again.

MIDI Notes

Each key can trigger up to four separate MIDI notes. This way it's possible to play single notes as well as chords.
You can choose different channels, instruments, and velocity values per key.
It's also possible to toggle notes: Turn them on when you press them once, turn them off again when you hit them a second time. Perfect for drum loops.

MidiMidi includes a lot of scale and chord presets. Examples: Minor, Major, Blues, Harmonic Minor, Phrygian,...
This way you can always play in key while you jam on your instrument!

7 easy Steps: The Quickstart Tutorial

  1. Buy MaKey MaKey at their website:
  2. Download MidiMidi, install it, start it.
  3. Connect one side of an alligator clip to the "earth" part of MaKey MaKey and the other side to yourself.
  4. Connect one side of an alligator clip to the "space" field of MaKey MaKey and the other side to a banana / a metal object / your mother in law / anything conductive.
  5. Now if you touch the object you should see the "space" pad in MidiMidi lighten up.
  6. Take a look at the settings and change the output device to something that works with your MIDI hardware or software. Use a virtual MIDI cable for Mac or Windows to send MIDI data to other software.
  7. Congratulations! You are ready to build the controller of your dreams now!

I used the makey makey since a long time but was blocked in my experimentations because of the midi limitation. With midi midi I can realize my ideas ! Thank you so much ! Ben F.
I'm trying Midi Midi since few days, and that's really a nice software, it rocks solid and is very light for cpu and ram. Damien T.
