Tiny Subversions

Is the DS region free...?
 

Yes.
 

That's wicked bitchin'. That said, since I don't already have a DS, I'll stick with wanting the equally bitchin' Korg Kaossilator.
 

Yeah, someone showed me that, and I must admit I'm excited by it as well.
I love my MicroKORG (lovingly modded into a homemade keytar of sorts with my addition of a guitar strap mounted to the case), so Korg on the DS just combines two great tastes for me right there.

I have synthesizers for older game boy models. People have been making synthesizer software for consoles/portables since they've existed: I find it interesting that now a synthesizer developers themselves are getting in on the bandwagon.
 

I could incorporate a DS into my music act.
 

My earlier comment here I eventually expanded into a full entry on my blog.

Which also, as a fun bonus, contains an anecdote of the time I built myself an interface to play music on my NES with a Guitar Hero guitar and DDR pad. ;)
