About: I'm a 36 year old DIY enthusiast from Vienna Austria with a strong background in mechatronics/automation. My DIY field is mainly video/audio/motion control. If you want to see what i do between posting it ...

I always wanted to make some sort of synth styled controller for my iPad synths and use a monotrons filter in the output.

This Instructable will be about how to build a minimoog styled iPad-mini controller.


  1. a lot of wooden profiles
  2. an akai lpd 25 keayboard
  3. a Korg Monotron (if you want to have an MS 20 LP in the output, and i bet you want that)
  4. a powered USB hub

Take a look at the photos for more details, one is a 1:1 drawing how i wanted it to look.

First things first, so i bought a lot of wooden profiles, and a wooden baseplate.

After i took some measurements on the AKAI keyboard, i decided to rip it apart, oposed from building it into its.

So i took a saw and freed the keys from plastic.

Take a look at the photos to see the profiles and how they fit the keyboard.

Step 2: THE DOCK

As i wanted (but never did) to use a small soundcard to get symmetrical outs, i used a USB-hub to power the soundcard.

If you dont want to do this, you dont need the hub, so all you gotta do is fit a lightning to USB cable into the box, and connect that to the keyboard.

    wow this is incredible. the only reason i didn't get that akai keyboard was that it has to be plugged in to a computer to be able to operate, which is not a portable solution at all. this solves all problems at once !!! thanks for sharing this, I've already forwarded it to my friend who has the akai :) just amazing work !

    Thanks :)) but you can use the akai without a computer on your ipad, just buy the camera connection kit, its a small lightning to usb cable which i use in this project too
