As a followup on my creation of custom-made visuals (though I haven't submitted any of them for a while), I just made my waveshape, Generic Scope, which consists of two lines horizontalized while LWdt and Pen respectively react to the music.
There were major issues with the shape, and I tweaked it several times.
Well (possibly besides that), thanks for trying it out as it's not a mod of others, but I'm saying it needs more tweaking to make it more clear; there are no edged outlines and no filling color (generally applies to Pen). I still need help!
