FDS pitch envelope editor interprets typed negative values as zero

[PixelFurret]

When typing values as numbers in the FDS instrument editor, all negative values act as zero upon hitting enter. The numbers that were input remain the same in the text box, and the tick length of the output is correct, but in the visual editor and in the instrument's sound, all negatives become zero. Subsequently, if the visual editor is clicked to change a value, the affected numbers in the text box update to be zero. Any negative values input using the visual editor function properly, though clicking on the text box and hitting enter reverts them again.

I was already aware of this, and am already using Dn (though I wasn't when I made this comment). Dn is indeed good- I won't deny that- but I do prefer 0cc's icon (not like it's that important, though).
