Greetings Diego Hi
Thanks for this tut, it’s great for use expressions.
just a tip:
in the expression

linear(value,5,70,0,150)

if you change the first value to a negative number like (-70) the brush on the “write-on” effect will go down the line as well (not just up or down), but
you have to set (almost frame by frame) on the “audio amplitude” layer keyframe’s to a negative position.
so,
with this you can get a effect most like the real seismograph.
