Hey everyone! πŸ‘‹ I'm a solo developer working full-time as a C# desktop app developer. I built AutoBandStudio on nights and weekends over the past few months.

Why I made this: I've been playing in bands since college. I always had melodies in my head, but turning them into full songs was the hard part β€” especially the accompaniment. There are amazing AI music tools out there that generate entire songs from text prompts. I wanted something different: a tool where I create the melody, and AI just helps with the backing track. Think of it like sketching a drawing and having AI color it in.

Tech behind it: The chord prediction model is a Transformer Encoder built and trained in PyTorch. As a C# developer, diving into Python and deep learning for the first time was... an experience πŸ˜…

Where it stands now: 650+ downloads across 58 countries, 5.0 rating on Microsoft Store. v2.0 just launched with guitar generation, drum editing, and a Pro subscription.

I'd love to hear your thoughts β€” what would make this more useful? What's missing? Thanks for checking it out! 🎡

Comment highlights

The AI chord prediction flows naturally with the melody , no awkward harmonies at all

It feels a lot like having a virtual bandmate: you throw out an idea and get a full, living arrangement in return

Love this approach. Preserving the original melody while letting AI handle arrangement feels way more creator-friendly than prompt-only generation. Curious how well it adapts across genres and tempos.
