Sorry for being late-ish...lol
Here you are...colors are provided via custom expressions so you can easily change them - the expression "out" is what you need to "map" to midi or OSC out

Nice example,thank you!

canvas_setFillStyle(c,out?oncolor:offcolor);

if a then b else c ----> a?b:c (Lemur manual, page 136)
if out is NOT 0 then if(out) returns true - if out=0, then if(out) returns false
so, instead of typing
Code: Select all
if (out==1) canvas_setFillStyle(c,oncolor);
else canvas_setFillStyle(c,offcolor);
we type
Code: Select all
canvas_setFillStyle(c,out?oncolor:offcolor);

As Softcore says, it's in the manual - but the manual doesn't really explain it very well - nowhere near as well as Softcore does himself.
