Bunny Retro Studio - Retro/8bit/MIDI music maker

The pocket-sized DAW for pixel-perfect tunes.

Making chiptune music shouldn't feel like programming a spaceship. Bunny Retro Studio is a lightweight, pattern-based music sequencer designed for indie devs and retro enthusiasts. Inspired by the ease of modern piano rolls but powered by the crunchy sounds of 8-bit, it is the fastest way to score your next pixel art game.

Whether you need a looping background track or a short jingle, just drag, drop, and export.

Features

• 4-Track Sequencing: Classic chiptune setup—Lead (Square), Second Lead (Saw), Bass (Triangle), and Noise Drums.
• Add more tracks as you want!
• Sound Design Controls: Don't just place notes—sculpt them. Adjust Attack, Decay, Sustain, and Release (ADSR) and Timbre per track.
• Multi-Bar Workflow: Write up to 8 bars of music using the intuitive "Page" system.
• Smart Piano Roll: A modern interface that supports dragging, resizing, and multi-selection.
• Save & Export: Save your projects as .json to edit later, or export instantly as High-Quality .WAV files ready for your game engine.
• GBA Aesthetic: A dark, comfortable UI inspired by the Game Boy Advance palette.
• NOTE: I am still thinking about giving this tool the ability to play more than 1 notes in 1 step of the same track. It is not conventional for retro/chiptune music creator, but may be useful. I don't know. Leave comments if you guys want that, and I will update the tool.

How to Install & Run

Important: Because this is a portable application, it does not install to your computer.

1. Download the .zip file.
2. Right-click the file and select "Extract All...".
3. Do not try to run the app from inside the zip file; it will not save files correctly.
4. Open the extracted folder and double-click bunny-retro-studio.exe.

Note: If Windows Defender warns you about an "Unknown Publisher," this is normal for indie tools. Click "More Info" then "Run Anyway."
