Mixer, reverb and mix analysis

The Mixer section in the side panel shapes where each track sits and how much room it gets. Everything you set here plays live and goes into the WAV export, which is rendered by the same audio engine the Tonegrid Pattern Renderer tool uses.

1. Pan the tracks

Under Mixer, move Melody pan and Drum pan. The value reads Centre, or for example 30% right or 40% left. Tonegrid uses an equal-power pan law, so a track keeps the same loudness wherever you place it, and a centred track is as loud as before panning existed.

A good starting point: drums slightly to one side (20–30%), the melody centred or slightly to the other side. Changes are heard immediately while the loop plays.

2. Choose a room and send tracks into it

Reverb room offers No reverb and seven rooms from the shared audio engine: Small room, Living room, Studio, Concert hall, Cathedral, Cave and Open forest. Each has a typical reverberation time, from 0.3 s in the studio to 5 s in the cathedral.

The room alone does nothing until you raise Melody reverb send or Drum reverb send. The send decides how much of each track goes into the room:

• Pads and bells sound wide with a melody send of 25–40%.
• Keep the drum send low (0–10%) so the beat stays tight.
• Long rooms (Concert hall, Cathedral) fill quickly: lower the send rather than the room.

With No reverb the send sliders are switched off.

3. Measure the mix

Press Analyse the mix… at the end of the Mixer section, or choose Export → Mix analysis (spectrum and levels)…. Pick the Range — Current pattern, one full loop or Whole song arrangement — and press Analyse.

Tonegrid renders the mix exactly like the WAV export and shows:

• Peak level and RMS level of the whole mix, and the Crest factor.
• Left channel peak / RMS and Right channel peak / RMS — panned tracks show up here.
• Spectral centroid (where the energy sits) and the Length of the rendered file.
• A spectrum chart with the strongest lines marked, the list of Strongest spectral lines, and a waveform overview.

If samples reach full scale, a note says how many will clip in the WAV file. Lower Volume or the track levels in the Sound section and analyse again. A silent mix (no squares or both tracks muted) is reported too.

4. Export

Open Export → Audio file (WAV, MP3, OGG …)… as before. The WAV is stereo at 44.1 kHz. A pattern loop is seamless: the ring-out of long notes and the reverb tail continue at the start of the loop, so it repeats without a gap. A song gets extra time at the end for the reverb to fade.

Live playback runs in your browser's Web Audio and the export in Tonegrid's engine. They use the same voices, pan law and reverb; tiny differences can remain, for example in the length of the reverb tail.

Tip: render without the app

Paste a project or share link into the Tonegrid Pattern Renderer tool (JSON API and MCP too) to get the same WAV file and the same level report — useful for scripts and AI agents.
