Diamond in the very rough? Hopefully it will get sorted because the GUI is extraordinary and the sound is great.

Problematic even at the reduced price. The dev should consider selling to a larger company that has the resources to make it work reliably. The asking price or royalties negotiated should be considerable because it's a truly brilliant GUI and when it works Circle produces some great sounds. Whatever company were to buy it would be getting an excellent property. Steinberg? NI? Hopefully not Apple. Unfortunately the current dev doesn't appear to have the resources required to address all the issues. In it's current form it appears to be an unfinished work. YMMV.
