 This is my fork of NitrousTracker which I use to haphazardly add features that I would like, which I will then pull request when they are cleaned up and done.
 
+Also please note: all the currently unfinished features here will be rewritten. The current implementation is extremely messy and buggy and just me testing how feasible different features are. Also, the current design of the FX keypad is not final.

 [Click here to download the latest artifact (nds builds)](https://nightly.link/prayerie/nitrictracker/workflows/build.yaml/new/NitricTracker.zip). Note that I just commit random stuff that may be broken here with no regard for stability, so it will probably suck to use (don't blame me if you get a random guru meditation error and lose any current work). This repo will not have any formal numbered releases, as when the changes here are stable I will just merge request NitrousTracker.
