Live coding

cling (an interative C++ interpreter) is for the live coding enverionment.

1. Install cling

On Mac and Linux using Homebrew
  1. open your command line software
  2. type brew install cling

2. Or download cling

Alternatively, you can download the right build for your machine:cling builds for Linux and MacOS

Or you still can compile/link zeroOne as any other c++ library and code with it as so.

How to use it

  1. open your synth ready to listen MIDI messages

  2. open your command line software

  3. run ./build.sh

  4. at cling's prompt load zeroone by entering the following lines:

    [cling]$ .L zeroone

    [cling]$ #include "../src/zoengine.h"

    [cling]$ zeroone()

  5. after message "zEROoNE on <((()))>" appears, copy/paste the code below:

Instrument 1 sends "C Major" chord notes to midi channel 1, 0.9 amplitude and 1/4 duration.

i1.play(n(
	({36,40,43}),
	0.9,
	{4},
))

and/or

Instrument 2 sends cycling c4,cs4 and d4 notes to midi channel 2, 0.5 amplitude, 1/4, 1/8, 1/4, 1/8, 1/4 duration sequence.

i2.play(n(
	{cycle({48,49,50},isync(2))},
	0.5,
	({4,8,4,8,4})
))

and/or

Instrument 3 sends cycling pentatonic minor scale notes to midi channel 3 and modulates cc channel 1 and 2.

i3.play(n(
	{cycle(
		scale_::transpose(scale_::pentatonicminor,5),
		isync(3))
	},
	0.9,
	({4,8,4,8,4})),
	cc(1,rnd(chop(10))),
	cc(2,bounce(0,127))
)

Make some noise!
