No band? Hertz Moon vBand builds you one.
Whether you sing, play an instrument, or both: Hertz Moon vBand listens to your track and generates a virtual band that plays like real musicians, following your melody, groove, notes and chords. For those just starting out and those who've made music for years.
App coming soonAvailable soon for WindowsWhat you can do
Generate your band
Import your track and get a virtual band playing along — bass, drums, guitar, keys — following your song's melody, groove, notes and chords. You receive the stems of each band instrument plus a full file with your original track together with the band: so you can balance the volumes however you like inside the app and save the mix your way. You can also export sheet music for every generated instrument.
AI Arranger
Let the AI arrange your track and apply the arrangement to your timeline. Pick the style you prefer: automatic, simple, or built around your song's sections.
Separate the tracks
Split any song into 6 separate tracks: drums, bass, guitar, piano/keys, vocals and uncategorized instruments. Perfect for studying a track, isolating the vocals, or rebuilding an arrangement from scratch.
Change the harmony
With the Harmony function you can reshape a song's harmony and hear it in a completely new light, choosing from many different styles.
Record in the app
Record your voice or your instrument right inside Hertz Moon vBand. Save it as-is, with audio cleanup and enhancement, or generate a virtual band from your vocal melody — just a few notes in tune, even without words.
Some functions use a credit system. Saving a standard recording is always free.
What makes us different
Many apps separate tracks or add ready-made backing. Hertz Moon vBand goes further: the virtual band doesn't repeat a generic pattern — it interprets your original track: your melody, your groove, your chords. It's like having real musicians who listen to what you've made and play along with you.

Hertz Moon vBand was born from a problem I lived firsthand.
I'm a self-taught guitar strummer and I love writing songs — I've even released a few on the music stores, without much luck. And I think I know why: voice and guitar alone often aren't enough to bring a track to life. I was missing a band.
For a long time I looked for an app that could generate a virtual band able to play along with me: one that follows my music and enriches it, instead of pasting ready-made patterns on top. All I found was MIDI and generic backing, nothing that did what I was really after. So I decided to build it myself, for me and for anyone who's run into the same problem.
I'm building Hertz Moon vBand on my own and self-taught — independent, and driven by one thing: the deep conviction that this idea deserves to exist. That's why development moves one step at a time — I'd rather grow the app with care than rush it. The virtual band in particular still has a long way to go, and I'll keep improving it over time so it sounds better and better on your compositions, instrumental or vocal.
If you choose to come aboard now, you're not just a user: the way you use it and the advice you share will help me make Hertz Moon vBand into what I dream it can be. We'll watch it grow together.
And if at some point you need gear — an instrument, headphones, cables, an audio interface, a mixer — you'll find what I genuinely recommend in the shop. Buying through it doesn't cost you a cent more, but it gives real support to the app's development. A small gesture that helps us grow together.
