Hi all,

does anyone knoe how i could create a knob like the one shown in the image below using SM? The grey area fills up in a circular fashion in a clockwise direction from 180 degrees, through 360 degrees and back round to 180 degrees again.

I guess i would probably just use an ellipse GUI element or something similar but i would need to define the area where it should be drawn and the calcs for that are giving me a headache.

I was just gonna modify the vector knob, removing the arc element and replacing the marker element (circle or line) with the bit i'm trying to work on.

Cheers in advance for any help.

hmm... you could draw an arc using a "fat" pen? maybe this example helps.

    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.
