"Repl Electric" perform live music programming.

Liveness is the key, controlling graphics and sound that respond to the space, the crowd and the moment.

Poetry and engineering woven together.

>Live Music Programming ♫

Programming source code is a means of a human communicating with a machine. The code is hidden away, never seen by anyone who uses the program. The nuances, beauty and communicative aspects of the code are lost, all thats left is 1s and 0s stuck inside your machine.


Live music programming allows humans to make the connection between the source code and its effect on the world. To watch the code grow along with its music.

As well as playing music we are also keen to share and inspire programmers to become musicians and musicians to become programmers.

>Read our Source Code

The code used to build our music is open and free for all to peer inside:
Repl Electric on Github.
Our code is sculpted in the various programming languages like Clojure or Ruby. And uses the open source audio environment Supercollider wrapped with Overtone or Sonic Pi.

>What is a REPL?

A REPL is a program which is constantly running with the following phases:

  • Reads (R)
  • Evaluates (E)
  • Prints (P)
  • Loops (L) back to Read

We send our programming code to this REPL which in turn generates our REPL music.
