DSO Quad suggestion and bugs.

This should be rather easy to implement for everybody with a minimal experience in software engineering.

I suggest you have a look at Petteri Aimonen’s page essentialscrap.com/dsoquad/freq.html, his “frequence response application” is an excellent starting point and very well commented. His instructions about how to install a freeware development environment on Windows are easy and they work (not like others here…).
