Bosca Ceoil: The Blue Album (or Bosca Ceoil Blue, for short) is a simple and beginner-friendly music making app. Using a step sequencer you can create anything from a simple beat to a complex melodic piece — with huge selection of synthesized instruments!
Bosca Ceoil Blue is a modern port of Terry Cavanagh's Bosca Ceoil, and attempts to preserve everything that made the original so approachable and intuitive. And just like the original, Bosca Ceoil Blue is absolutely free and provided under a permissive open source license, should you need to modify it.
Begin writing music quickly with a playful piano roll sequencer. Create patterns of notes and experiment with timing and tonality to find your unique sound. Adjust the scale to give yourself a constraint that ensures your music always sounds great!
Just as playfully rearrange your patterns on the timeline, create variations and make adjustments. Use up to 8 channels to play multiple patterns and instruments in parallel. Block by block, build your multi-minute song!
Powered by a versatile software synthesizer, Bosca Ceoil Blue offers you pretty much any instrument you can think of! Don't like how your tune sounds with a piano? Swap it for a guitar with a swift adjustment. If you feel adventurous, make sure to take a look at instrument tuning.
Export your creations to WAV and MIDI. Share them with the world, or use them for your next game or video!
Bosca Ceoil Blue is currently in the beta phase! This means it's feature complete and is looking for users and testers to offer feedback and validate its stability.

The project is being developed using the latest available build of Godot 4.3. As this version of the engine is still unstable, some bugs unrelated to this project must be expected.
To work on Bosca Ceoil Blue you need to:
- Check out this repository, or download it as a ZIP archive.
- Get the latest release of GDSiON 0.7 and extract it into the
binfolder in the project root. - Open and edit the project with Godot 4.3.
Original Bosca Ceoil is a great tool for budding musicians and game developers. It's almost perfect, but can still benefit from some UX enhancements and improvements to its composing features. It's also using an outdated technology stack which makes it hard to impossible to run it on modern systems, namely macOS and web.
The goal of the Bosca Ceoil Blue project is to make Bosca Ceoil more accessible to today's users and also to new contributors. We achieve this by reimplementing the entire application with a more modern set of tools, as a Godot engine project.
A general-purpose game engine like Godot gives the project means to run on Linux, macOS, and Windows, as well as on web and even mobile phones — almost hassle-free. It's also a popular tool among many game developers, which should make Bosca Ceoil Blue an inviting project for new collaborators.
