Intro
I am a fan of Look Mum No Computer, In one of his videos he mentioned about the website Music From Outer Space and the book Make: Analog Synthesizers which I have brought and I am currently reading through.
Sequencer
I wanted something that I could connect up to a computer via USB to use software synths like VCVRack or for connecting up to Garageband and maybe later Logic Pro. I also wanted something that is able to control hardware synths with Pitch CV, Velocity CV and Gate control or via MIDI inputs and outputs. The Keystep Pro provides all 3, via USB, MIDI and mono 3.5mm output jacks.

Eurorack Case and Power
I have seen a 3D Printed Eurorack case that I would like to make called The SP1 by Spillerphoto.com on Printables

Parts For Testing
To test eurorack modules, I will be firstly building them up on a breadboard, powered by 2 9V Batteries. I also plan on building a cheap DIY Oscilloscope kit into a 3D printed Eurorack Module. I did not want to spend a lot of money on a decent oscilloscope, I just need one "good enough" to help with visualising waveforms and to get an idea of what output a module is producing.
