Full Description
Whether you need a convincing demo vocal to pitch your song, seamless harmony layers to sit beneath a real performance, or a full synthesised lead vocal for your production, AI vocal programming delivers a fast, flexible, and professional solution — without the cost or scheduling complexity of a studio session.
Zinn Digital, based in London, England, uses professional off-the-shelf voice databases to synthesise English vocals tuned to sound as natural as possible. We work from your melody and lyrics, dialling in the engine to match your genre, BPM, and key. We do not perform voice-to-voice transformations, and we never clone, copy, or modify copyrighted vocal performances.
**What AI Vocal Synthesis Can Do For You**
AI vocal programming is a genuinely versatile tool across a wide range of production scenarios:
- Create demo vocals to present ideas to bands, singers, or collaborators
- Add harmony or support vocals that sit alongside a real vocal performance
- Develop heavily processed vocal effects — vocoders, pitch shifters, experimental tones
- Incorporate gang vocals or choir layers into your arrangement
- Serve as the primary vocal performance in a finished production
**What You Receive**
Every delivery includes two studio-quality WAV stems for maximum flexibility in your mix:
- Raw generated vocal as a WAV file at 48 kHz / 24-bit stereo
- Processed vocal (EQ, compression, de-esser, exciter applied) as a WAV file at 48 kHz / 24-bit stereo
Both stems are delivered as downloads, ready to drop straight into your DAW session.
**What We Need From You**
To get started, please provide:
- Genre, BPM, and key of your track
- Male or female vocal preference
- Complete lyrics
- A MIDI file containing the topline melody, or a lead sheet with the song key
- For harmony vocal programming: the harmonic relationships required (e.g. a 3rd up or down from the main vocal)
- For independent additional melody lines: the melody as MIDI or sheet music
**Who This Is For**
This service suits producers, songwriters, composers, and artists at any stage — from early-stage demos that need a vocal reference to finished productions seeking polished, processed vocal layers. If you have the melody and the lyrics, Zinn Digital handles the rest.
**Why Zinn Digital**
Zinn Digital is a London-based digital production studio with a clear, professional workflow and a focus on delivering natural-sounding results from synthesised sources. Every vocal line is programmed with care — not simply generated and sent — ensuring the output serves your music rather than fighting it.

Frequently Asked Questions
A MIDI file containing your topline melody is ideal and gives the most accurate result. If you do not have a MIDI file, a lead sheet showing the melody notes alongside the song key is also accepted. For additional independent melody lines, please provide MIDI or sheet music rather than an audio reference alone.
You can specify male or female, and provide genre context (e.g. pop, R&B, rock) so the programming is tuned accordingly. We work with professional off-the-shelf voice databases, so the available voice characters are determined by those databases rather than by bespoke casting.
No. Zinn Digital does not perform voice-to-voice transformations and never clones, copies, or modifies copyrighted vocal performances. All vocals are synthesised fresh from pre-trained voice databases using your supplied melody and lyrics.
A revision covers adjustments to the vocal programming within the agreed scope — for example, timing tweaks, phrasing changes, or processing adjustments. Changes to the underlying lyrics or melody after delivery may require a new order or an additional charge.
All vocal synthesis is in English. The voice databases used are trained on English-language material.
Once your order is placed, use the order manager to upload your MIDI file (or lead sheet), lyrics document, and any notes about genre, BPM, key, and vocal preferences. Clear, complete information at the start means faster delivery and fewer revision rounds.
The stems are delivered for your use in your production. Please ensure your intended use aligns with the licence terms of the voice database in use. If you have a specific commercial release in mind, mention it in your order notes and we can confirm suitability.
