-## Installing Python MIDI
-
-This is a little tricky, but if you follow these steps you should get it installed in no time:
-
-First you'll need some dependencies, install them with: `sudo apt-get install python-dev libasound2-dev swig`
-
-Next, you need to clone the GitHub repo: `git clone https://github.com/vishnubob/python-midi`
-
-And install it: `cd python-midi && sudo ./setup.py install`
-
-If it installs properly, you should get a handy new tool `mididumphw.py` which will tell you what MIDI-compatible synths you've got running and what Client/Port IDs you'll need to connect to to use them.
-
-## Using `midi-piano.py`
-
-You'll find the MIDI Piano example in the examples folder of this repository, or in `~/Pimoroni/piano-hat` if you used our installer script. By default it supports SunVox and yoshimi:
-
-* Sunvox ( Get it from http://www.warmplace.ru/soft/sunvox/ )
-* Yoshimi ( `sudo apt-get install yoshimi` )
-
-Run either of these synths first, and then run `sudo ./midi-piano.py` and start playing. For best results, you should use a Pi 2- especially with Yoshimi which can be a bit taxing on the older models.
