Bosca Ceoil is all about looping, and designed that way at its heart. Songs are built up from lots of tiny 16 note patterns – the intended workflow is that you loop over these single patterns until you have something you like, then you start making variations. If you approach it this way, you’ll find it’s pretty decent at doing that – but it’s not very good at other things, like say, long melody lines. It is what it is! I made it for myself, and the way I work, but hopefully some of you out there will find it useful too. It’s free, and open source under the FreeBSD licence. If anyone wants to port it/fork it, go for it! »
