Many thanks Geert! I will bear that in mind. Did you see my post that I found that the reason why I was getting no sound from cello or clarinet was that the windpipe on my Pico was Imperceptively loose? when I pushed it gently into the instrument body it played fine, with little breath required.
I wonder if this potential problem has ever been mentioned anywhere on this website?
I am still hoping for advice about installing 1.4.12. After running setup.exe the upload available still shows, and "about EigenD " still says I only have version 1.4.11.
