Hey, welcome!

This is a project for remote online jamming via live coding. The system uses a SonicPi server as sound engine which you can send commands / music generating code to via this webpage. The music from all users gets mixed down and streamed to this website via a standard HTTP audio stream:

Your browser does not support the audio tag.

You can use all commands and syntax that are supported by SonicPi. Below, we provided a few simple code snippets and examples to get you started. But there is also a great tutorial about the SonicPi language and lots of code snippets from others on the internet.

In online jamming, it's very important that music is in sync with others. To ensure this, SonicPi has a concept called cues. The server provides a basic metronome cue, which we kindly ask you to use in order to sync up with the rest. See code snippets below!

In general, don't be afraid, just play around and have fun. It's just sounds :)

Basic commands

Playing a note

play :c4

Playing a tone ladder

play :c4
sleep 1
play :d4
sleep 1
play :e4

Playing a chord

play :c4
play :d4
play :e4

Playing a chord, better

play (chord :c4, :major)

Use a live loop to loop your code and sync up with others

live_loop :loopname do
  sync :metro

  play (chord :c4, :major)
  sleep 1
end

:loopname can be an arbitrary name that identifies the loop. Please note that your loop keeps existing and playing even if you close this webpage. So please consider stopping your loop when you leave by overwriting your loop with an emtpy one, or simply by writing stop as first command within your loop:

live_loop :loopname do
  sync :metro

  stop
  play (chord :c4, :major)
  sleep 1
end

The sleep time is in units of a beat. Also fractional values are possible to get eighth (0.5) etc.

Use different sounds / synths

use_synth :tb303

Other synth are e.g. :pulse, :dsaw, :fm, :prophet. See https://github.com/sonic-pi-net/sonic-pi/blob/main/etc/doc/cheatsheets/synths.md for a full list of available synths.

You can control the parameters of the synths using e.g. use_synth_defaults attack: 0.1, release: 0.7, cutoff: 50. These parameters can also be appended to the play command.

Playing samples

The system has a lot of nice samples which you can use and mangle.

Playing a sample

sample :loop_amen

There are lots of drum samples like :drum_heavy_kick, or :drum_snare_hard. But there are also other kinds of loops and samples like :ambi_drone or :loop_3d_printer. Get a full list here: https://github.com/sonic-pi-net/sonic-pi/blob/main/etc/doc/cheatsheets/samples.md

You can mangle the loop using beat stretch, speed (also reverse), and filtering, e.g.

sample :loop_amen, beat_stretch: 4, cutoff: 70

Other parameters are rate: 0,5, rate: -1 (for reverse). There is also rpitch 2 for transposing in semitones.

Using FX

You can embed your code in fx blocks:

live_loop :loopname do
  sync :metro
	
  with_fx :reverb, room: 2, do
    play :c4
    sleep 1
  end
end

A full list of all effects and their parameters can be found here: https://github.com/sonic-pi-net/sonic-pi/blob/main/etc/doc/cheatsheets/fx.md

More advanced snippets

Many examples can be found on github, e.g.:
