Change timbre (voice trainer)

What is this?

With Change timbre you choose how the voice tracks extracted by the voice trainer should sound. Chorilo offers several AI timbres — from warm and vocal to clear and instrumental. Each timbre has its strengths during practice.

How to change the timbre

1. Open the piece and switch to the voice trainer.
2. Click Change sound or open the settings and choose the timbre area.
3. Listen to the previews — each timbre is demonstrated with a short example.
4. Pick the desired timbre.
5. Confirm the choice. The tracks are re-rendered in the background (1–3 minutes).
6. As soon as processing is finished, you can listen to the new tracks.

Which timbres are available

• Warm vocal — natural choir voice, good for beginners and when learning new pieces
• Clear vocal — precise, well-articulated voice, ideal for rhythmically complex passages
• Instrumental (piano) — voice tracks as piano sound, perfect for pure pitch training
• Instrumental (strings) — voice tracks with a soft string sound
• Synthetic — neutral, artificial sound, easy to distinguish between voices

The exact choice may vary depending on plan and AI update status — new timbres are added regularly.

When which sound is worth it

• First learning: warm vocal or clear vocal — helps to internalise the melody as a voice.
• Pitch training: piano — clear pitches, no vocal colouring.
• Rhythmically complex pieces: clear vocal or synthetic — precise attacks.
• Classical works with accompaniment: strings — fits stylistically.

Permission

To change the timbre you need the sheet_music.edit permission. Because the change triggers reprocessing, it is restricted to editors — otherwise server resources would be used up quickly.

Tips

• Try several timbres — the render only takes a few minutes and you can switch back at any time.
• Not every timbre suits every piece: for classical works, strings often sound more natural than synth, for pop arrangements it is the other way round.
• Ask your choir which timbre they prefer when practising — the choice is global for everyone.
• Do not switch too often, especially not right before important performances — members get used to a particular sound.
