Yeah...I'm finding mine to be quite noisy too. I think I'm going to go back to 2.77 as well and deal with the jumpy numbers. I should be digging tones and not numbers anyways.
That is strange they removed the previous versions from their website. Say someone just wanted to compare/experiment with 2.78 and now their stuck with it or find a copy like Drew. Mine came with 2.78 and I tried 2.77 and prefer as well.
Yes I tried to find 2.77 with no luck. Luckliy I had it from when I first got my Simplex still on my desktop. Worked like a charm. Now to give it a try. I have noticed it seems more noisy/chattery, but that could be the difference in sensitivity? I will field try it later today.
