Bosca Ceoil v2.0


I’ve very happy to announce a brand new version of my beginner’s music making tool Bosca Ceoil! This is version 2.0, the first major update since it was released in 2013. This new version of the tool is a significant update, and adds lots of features and improvements. Head to to download it!

If you’re totally new to Bosca Ceoil, the new site should tell you everything you need to know about what it is and what it can do. If you’ve used it before, here’s what’s changed:


Midi and XM Support

A major problem that Bosca always had is that it was kind of a dead end: if you made a song with it, you could save it as a .ceol, or export it as a .wav – but that was that.

So one of the most important things that’s new is support for exporting as a midi file! Midi files are supported by lots of popular music applications, so this means that it’s now possible to, for example, use Bosca to compose the actual notes, and then later import the song into something like FLStudio so you can add VST instruments.

Also, in addition to midis, Bosca can now also export .XM files and .MML files, thanks to contributions by Rob Hunter!


Resizable Window

I made Bosca Ceoil the same way I make games – with a fixed resolution, running at 60FPS. Which is great for games, but not so good for an app that you might want to leave running in the background while you work on other stuff, say.

The new version of Bosca has a proper resizeable window, so you can see a lot more of the song you’re composing. It’s something it should have had all along, and it makes it infinitely nicer to work with!

It’s also gotten some major performance boosts with caching and CPU throttling, and is generally just much happier about running in the background than it used to be.


Nicer GUI

Bosca’s GUI has had a makeover. Things are generally brighter, clearer and more responsive!

Web Version

Thanks for Chris Kim, you can now use Bosca right in your web browser, without downloading anything! Try it here!


Built in Tutorial

At long last, Bosca has a built in tutorial, with nice, clear little pop up windows! This is something I’m really happy about – Bosca’s a beginner’s tool, and this does a lot to make it that bit more accessible.

Bosca Ceoil is a completely free, open source project, and I’m very grateful to the contributions others have made to it – especially Chris Kim for his flash web port, Rob Hunter for writing the .XM and .MML exporters, and Damien L, who forked Bosca back to Air 2.6 so that it could be used on Linux. Thank you so much for your help!

Hope you enjoy the new version!

    Thank you so much Terry! This tool was already amazing and now I’m WAY TOO EXCITED about the resizable window 😀

    The ability to limit the available notes to those within a given scale or chord is quite useful and the ease with which it’s possible to do so is excellent.

    This is a fantastic program. I’ve been using it to compose music for the past 6 months since I’ve found it and I’m incredibly exited to be able to export what I’ve done to Midi and experiment on different platforms! This is seriously the perfect beginner’s tool to music tracking. I actually recently used Bosca Ceoil to teach the basics of music to a Boys and Girls Club group and it went over really well. I hope to continue using it as a teaching tool. Thanks so much for the added support for this powerful tool!

    Bosca is awesome!

    You don’t know how grateful I am to have access to this resource for free. This is everything I’ve ever wanted in a basic music making program, and it excludes everything in sound design that’s too complicated for me to understand! It’s absolutely perfect

    Thank you so much Terry.
