All I can say is, Whoa!
I’ve been toying around with NitroTracker for a while now, and I frequently check for updates to it, and Colors! Well, it’s great to see an update finally come up NitroTracker. v0.4 has some great features, the ability to envelope your samples is a great addition to the list of tools. You can see the updated list of features over at the NitroTracker Website.
Seriously, if you have a DS… Get yourself a homebrew card and download this awesome tool. You will not regret it! 🙂
Oh, and thanks for the improved Left Handed support. 😉
