I thought that was a good idea,
so here it is->
I tried with mouse-overs,
but there is some bug which means it doesn't redraw while dragging.
I'm sure this can be simpler,
maybe someone want to take a stab at it with ruby.
Hope u have fun with it!
And welcome mates, glad yous like my module.
Oh-it's harder now to make it more than one octave,
or to resize it, maybe I will have another crack with these things in mind soon.
edit-I got some of the grid position figures wrong,
and also a trigger delay wasn't long enough-
so I have modified the file.
Let me know what else is wrong with it if u find something
Cheers!
