Problem resolved, thanks to some great support from Ardours freenode channel. I simply needed to uninstall csladspa from my OS ( Linux Mint -19) I learned this was a known problem, but not yet addressed in the LTS version I am using.

Yeah a well-known issue with recent Ubuntu (and Ubuntu derivatives): https://bugs.launchpad.net/ubuntu/+source/csound/+bug/1754944
