I love this, perfect to create simple music loops. However, this no longer works on the Mac; it needs to be updated for the new MacOS. Still works on Windows, but I'd love to be able to use this program with my Mac! Hopefully this gets fixed soon!

really great! thanks for the software!


Hi. Thanks for developing the great tool. Unfortunately it doesn't work on Mac anymore. Are you planning to update the Mac version to 64 bit?

Hi ! I love it. I am a hobbyist developer. I am not musician at all, but I have been able to do the musics of my 1st game with this great tool. The game is published on itch.io .  It's a free 2d adventure platformer: Nightmare Therapy. If you want, feel free to give me your feedback on the musics, and anything you want ;)

I like it!
But is there a way to change volume for one single note?

No longer works on Mac as Catalina has taken away 32bit apps.  Will this be updated?

I love this so much. The tutorial is amazing, more serious DAWs should have run-throughs like that.


Very easy to use!
I like it, can you make a mobile port ?


Hey! I LOVE this application, could you please make a mobile version? I would love it if you did! Thanks!

It's a great app but whenever I load a file the song comes out slow and distorted. Does anyone know how to solve this problem?

it's so easy and fun to use. thanks for this!

hi, can you update the Mac system's software? I cannot install it

Can you import samples or wavs for instruments? I'm asking because all the instruments sound the same. Am I missing a setting?

Nope, sorry!


Interesting tool.  Aren't you the guy that wrote one of my favorite casual games (Super Hexagon)?  I'm going to have to check out some of your other stuff.  I haven't gotten around to checking out VVVVVV yet, but definitely among games I own.  Not a lot of time for gaming these days.  Making them yes, playing them no.  You should check out the FlatRedBall project sometime if you're interested at all in developing in C#.  Very cool framework that works with MonoGame and the author is very helpful.

That happened to me to, try restarting? It fixes it eventually.

An update would be marvelous, app is great


Can you add a "do you want to quit" warning? I accidentaly pressed esc and now all my progress is gone and so is pretty much my will to live.


I like it, but can you add these features:

1. making your own instruments (and choosing to convert them into 8 / 16 bit_

2. adding effects for specific parts

3. (either this one or another one) real life instruments (no 8/16 bit music)

Love it! All my game music is made with this. (So far.) The editor is accessible, but deep. Couldn't make it better if I tried.

Any tips on which instruments sound best? I'd like to make music similar to 2D Zeldas

Couldn't say. Look in the chiptune section, it has lots of beeps and boops.

It is cool! Please, add sampler and advanced effect mastering. Then it will be perfect.

This is amazing! Thank you Terry!

I would adore undo functionality and/or a one-click save feature (or Ctrl+Z/Ctrl+S would be amazing too).

When I click to save, it asks me to navigate from my desktop folder each time. For now, I've added a shortcut from my desktop folder to my Bosca Ceoil music folder, to make saving faster. I like to save my work often!

Thanks again!


it's amazing, made a buncha music for my undertale-like game, and can u do the same thing, but with real sounds?

Won't run on Ubuntu 18.10.  Here's the log https://pastebin.com/Tu8dYrpp

got it on boscaceoil.net

Pressing Alt causes the program to go into a state where it freezes for a few seconds after any mouse movement.

i keep getting an adobe AIR error that wont let me open the program

I'm having trouble saving. I export the file, but then it's not in the folder, and I can't prod it to save into the folders I want it to save into to start. Then it can open the file, but I can't find it in the folder that it says it's saving into.

Found the problem!

I'd installed it through the itch.io app.

Deleted post

its a great program! would be my goto program for music were I able to have variable length patterns! keep up the good work! =)

Oh wow I definitely need to check this out!

Great application for developing music! 

A question though, how do you remove instruments and  patterns(arrangements)?

 Though they do not effect the sounds and patterns, what so ever, they do take up UI space and makes navigating both the instruments and patterns more difficult. 

A possible "conflict" in the removal of an instrument is the case where targeted instrument is in-use. You could probably handle this by defaulting all patterns using the instrument (no longer available) to the another instrument (possibly the instrument in slot one).

Another possible "conflict" is the removal of all instruments, which can be dealt with by defaulting to the piano instrument. 

In the patterns case, you ought to simply remove the pattern from arrangement if they are no longer available; a lot more simpler (maybe).

And while we're at it, though not necessary, rearrangements of instruments and patterns would be cool. I haven't taken a look at the source yet, but hopefully shifting data up and down isn't too difficult.

But even without the above, the application still works. It's just tedious to explain the partners that those were instruments or patterns that were once consider but abandoned and could not be removed from the list (And that brings up aliasing for the list... guess that would be asking for too much).

Thanks for the cool tool.

I just had the very same question (removing patterns) and after some experimenting I found out that you can remove pattern by dragging them into the lower-right corner of the tool. Simply click and hold on an entry in the patterns list, then the delete button appears in the bottom-right and you can drag it onto that button to delete it.

I LOVE it!!

Whenever I try to make different sounds it automatically changes the whole entire song into the same sound.

PLEASE FIX THIS!!!!!!!!!!!!!!!


this isnt a bug its simply you forgot to add a new instrument may i suggest this full tutorial to explain everything bosca ceoil has to offer 


Can you add a ctrl + z function that rewinds an action, i've deleted notes that I wanted to place back and I keep hitting ctrl + z to go back but it doesn't work.



I've been looking for something like this forever! It's so simple and easy to use, but the music sounds great

this tools is amazing. The easiest I 've used

Can you plz make it where you have unlimeted notes.

Amazing tool, thank you!

this is awesome very useful
