GUI coordinate system

Why is it that the coordinate system for the GUI has the origin start at the 'top left' as opposed to the standard 'bottom left'? Programming GUI elements seems a little backwards, at least to me.

(I know its a relatively simple fix, but in large, graphic-intensive projects, it can be tiresome)

Also, programming angles is opposite of the standard 'counter-clockwise' used in the mathematics and engineering fields. (Once again there is a simple solution to this, I'm mostly asking out of curiosity)

Are these US standards that I'm used to, and if not, are there specific reasons for the things I mentioned?

I think you can blame Xerox/Apple for the upper-left=0,0 standard. It's a programming convention for GUIs.

I'm not so sure about rotation direction but since it just involves flipping the sign it's no big thing to change.

There's probably quite a few of us out there 😉

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
