# Cyber Cat MIDI Keyboard
## Overview
https://youtu.be/iDwmzcKgweY
You can transform a toy keyboard into a highly customized MIDI controller, perfect for laying down synthwave pads on your favorite hardware or software synthesizer.
All it takes is an Adafruit Kee Boar KB2040 running CircuitPython, a Meowsic cat piano, and the desire to be awesome. Plus some soldering and a bit of paint.

[STEMMA QT / Qwiic JST SH 4-Pin Cable - 50mm Long](https://www.adafruit.com/product/4399)
This 4-wire cable is 50mm / 1.9" long and fitted with JST SH female 4-pin connectors on both ends. Compared with the chunkier JST PH these are 1mm pitch instead of 2mm, but still have a nice latching feel, while being easy to insert and remove.

## Optional
You can get some spray primer, paint, and clear coat at your local hardware or art supply store if you want to paint the keyboard.
## Synthesizer
You can use any hardware synth that accepts DIN-5 MIDI (using an adapter cable from TRS-A) or TRS MIDI (may require TRS-A to TRS-B cable or adapter). You can control software synths that can be a USB MIDI host, such as an iOS device or computer.
A great free synth to use on iOS is [AudioKit Synth One](https://audiokitpro.com/synth/).
