A tiny command-line midi sequencer for live coding. (For ableton link compatible version go here)

• Sends MIDI messages to a chosen MIDI channel. Default is 1.

• 1 instrument or 1 CC

7 instances of line running simultaneously. 1 for notes, 6 cc. (Using tmux to split macOS terminal into 7 terminals)

• Go to Actions page, to section Artifacts, download and unzip the file
• Go to the build folder, type ./line and press Enter

• Just unzip line_0.4.24_Mac_Intel_build.zip file
• Go to the build folder, type ./line and press Enter

• readline library (should be already on your system, if not, you have to install it)
• CMake

git clone --recursive https://github.com/pd3v/line.git

(CMake is necessary)

• Go to line's folder

In command-line, type (1. as Admin) and Enter:

1. ./build.sh

2. cd build

3. ./line

Now run your favorite synth, sampler, DAW, or other MIDI receiver!

With line running, type:
