Thanks for the reponse Deiter! I asked because I don't have the
module yet, so couldn't test. I suspected that it would be AC coupled
(makes sense for its intended purpose). I'm basically weighing up
module options at the moment for future purchases to add to my synth.
I'll probably get the comparator at some stage as well.
Thanks again.
