FoxDot: Live Coding with Python & SuperCollider

This site is the home of the Live Coding environment, FoxDot, which was created in 2015 to try and open the pathways to Live Coding for users who may be new to programming and want to use it create music quickly and easily. FoxDot is an easy-to-use Python library that creates an interactive programming environment and talks to the powerful sound synthesis engine, called SuperCollider to  make music. FoxDot schedules musical events in a user-friendly and easy-to-grasp manner that makes live coding easy and fun for both programming newcomers and veterans alike. Ready to get going? You can find details on how to install here. Remember to check out the starter guide or have a look at FoxDot in action below for a few useful tips. If you’re having any issues with FoxDot or SuperCollider, have a look at the F.A.Q. or ask a question on the discussion forum.

PyDev of the Week: Ryan Kirkbride

PyDevOfTheWeek, Python

This week we welcome Ryan Kirkbride (@ryankirkbride26) as our PyDev of the Week! Ryan is the creator of Foxdot, a live coding library for live coding music in an interactive Python editor. You can see what projects Ryan is a part of by going to his Github page. Let’s take a few moments to get to know Ryan!

Can you tell us a little about yourself (hobbies, education, etc):

I’m currently doing a PhD at the University of Leeds in the School of Music researching collaborative tools for live coding music. Live coding is basically interactive programming for creating music or visuals and probably my favourite thing to do right now. There’s a growing scene called “Algorave” where live coders get together to make music for people to dance to and they’re a lot of fun to perform at.

Why did you start using Python?

I started using Python during my first year of university when I was studying computer science. It’s such as great language for beginners but there’s also so much to learn as you use it more and more.
