[bús-ka kyó-al] — a music box.

Bosca Ceoil: The Blue Album (or Bosca Ceoil Blue, for short) is a simple and beginner-friendly app for making music. 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.

Features

Playful and intuitive pattern editor

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!

Drag'n'drop-based compositor and arrangement editor

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!

Over 300 synthesized instruments

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.

Ready for production and consumption

Export your creations to WAV, MIDI, and XM. Share them with the world, or use them for your next game or video!
