Rendering

This content is for v0.7. Switch to the latest version for up-to-date documentation.

Resonon renders audio offline to stereo WAV files at maximum speed. Pattern loops can be bounced to disk for use in DAWs or distribution.

Project Metadata

Set project metadata before rendering. The title determines the output folder name (falls back to “untitled” if unset):

project_title("House Beat");
project_artist("RESONON");

Pattern Rendering

Use render() to bounce pattern loops for a given number of cycles:

Call	Output
`render(cycles)`	Master mix
`render(track, cycles)`	Single track
`render(master, cycles)`	Master mix (explicit)
`render(#[tracks], cycles)`	Each track as separate WAV
`render(#[tracks, master], cycles)`	Tracks + master mixdown
`render_master(cycles)`	Master mix (convenience)

render(4);                                // Master mix, 4 cycles
render(drums, 4);                         // Single track
render(#[drums, hats, bass], 4);          // Multiple tracks
render(#[drums, hats, bass, master], 4);  // Tracks + master mix
render_master(4);                         // Master mix shorthand

Output Format

Property	Value
Format	WAV (PCM)
Channels	Stereo
Sample rate	48,000 Hz
Bit depth	24-bit integer

These are fixed defaults.

Output Directory

Renders are written to:

renders/{project}/{project}_{YYYY-MM-DD_HH-MM-SS}/
  kicks.wav
  snares.wav
  hats.wav
  master.wav

The project name is sanitized from project_title(): lowercased, special characters replaced with underscores, consecutive underscores collapsed, trimmed, and capped at 50 characters. Empty or all-special-character titles fall back to “untitled”.

Example: "Track #1 (Final)" becomes track_1_final.

Rendering Behavior

Offline speed — rendering runs at maximum speed, not constrained to real-time
Audio paused — live audio output is paused during a render and resumes automatically when it finishes
Progress — a progress bar shows the current cycle, total cycles, and estimated time remaining

Examples

Multi-Track Pattern Render

project_title("House Beat");
project_artist("RESONON");

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

// Tracks
let kicks = AudioTrack("kicks");
kicks.load_instrument(Sampler(Kit("cr78")));
kicks << [bd*4];

let snares = AudioTrack("snares");
snares.load_instrument(Sampler(Kit("cr78")));
snares << [_ cp].fast(2);

let hats = AudioTrack("hats");
hats.load_instrument(Sampler(Kit("cr78")));
hats << [_ hh].fast(4);

// Effects
kicks.load_effect(Lowpass(600));
snares.load_effect(Delay(0.2, 0.3));
hats.load_effect(Highpass(3000));

// Render 4 cycles with all stems + master
render(#[kicks, snares, hats, master], 4);
