I've just sold my Novation Peak. It's a great synth but not for me.
I couldn't manage to find nor to create "vintage" sounds,as you can hear in late 70s/early 80s post punk & synth pop/minimal wave songs. It sounds too modern, probably. Or maybe I didn't find the sweet spots.
Here's a bank of 40 presets for free, for your Novation Peak or Summit synth. I think it's OK but I couldn't do better.
