RESONON

Render a Song

A song made with arrange() knows its own length, so the render can be exactly as long as the song.

Render the song

Section titled “Render the song”

End the project’s src/main.non with the song, song.play(), and a render as long as the song:

use "std/instruments" { Sampler, Kit };


set_project_title("My Song");


let drums = AudioTrack("drums");
drums.set_instrument(Sampler(Kit("CR-78")));


let verse = section(4);
verse[drums] << [bd _ sd _];


let chorus = section(4);
chorus[drums] << [bd sd bd sd];


let song = arrange(#[verse * 2, chorus]);
song.play();
render(master, song.length());

song.play() puts the song on its tracks. render() plays it from the start, for song.length() cycles. In the project folder, run:

Terminal window
resonon run

The mix is in renders/my_song_<date>_<time>/master.wav.

Render stems with it

Section titled “Render stems with it”

List the tracks beside master:

render(#[drums, master], song.length());

Each track is written as its own WAV, beside master.wav.

The render stops at the song’s last cycle, so a reverb or delay still sounding there is cut. What else a render leaves out is in What a render contains.
