I am kind of work till after midnight every day in my day job busy at the moment. I would like to get back into open source development when I have a bit of breathing room.

I like the modular approach taken by non daw... I would like to see the pro audio infrastructure in linux get to the point where it can support an application like this really well. I have in mind perhaps a few small improvements and I would like to see it be able to use the new LADI infrastructure...

I took a quick peak at the sequencer (sequencers are not normally part of my workflow - or rather I haven't found one that really suits me yet).

With regards to not being able to put in out of scale notes  it seems you can get around that by choosing a chromatic scale type.
