Hello,
I am currently working on a library for Axe that will allow you to use music alongside your games.  I call it Axe Clef, and it will come with a full fledged music editor to make it easier to make your music run inside your games.  It should allow you to continue to have a game while the music is running, and will only work at 15MHz.

Probably beeps.  I'm thinking about chords as well.  We'll see
But they will be musical beeps.

Awesome!  This sounds really nice!  What notes will this have support for?  How many part chords?  4 part chords would be great.

This sounds really neat.

Yay! I hope this is out in time to implement into Nostalgia! (Maybe)
Or perhaps I've said too much...

Anyways, I hope this gets finished, and I'm sure it will.

Cool.
Does anyone else agree when I say that 4 notes played in the space of four microseconds over and over would sound like one chord?

Not to my knowledge, but you can always try it out and see.

I have no idea how you plan on implementing this, but it sounds uber cool!

That's exactly what I'm thinking.  Will this be done with Axe or straight Asm?  Will it use interrupts?

Edit:
Are you making this like a keyboard or like Finale/Sibelius for inputting notes into it?

<offtopic>No, I use Finale Notepad 2008. </offtopic>

yeah I tried chords before and it sounds so crunchy

You can make chords in the style of Commodore 64, though, but they aren't really chords. I would go for 1 note at a time for now, I think
