I have posted two minor software tools on my website at http://www.bwong.ca
etrcalc.pd is a Pure Data patch that calculates the closest match to an interval within any equal temperament tuning.
ethan-00.zip is a Windows only executable file that displays tuning data in cents and frequency ratio for any equal temperament tuning.
Obviously these have nothing specifically to do with Csound, they are just my learning tutorials for a couple of new programming languages, but perhaps someone might find them useful utilities for composition or synth design, as I do.
etrcalc2.pd
Maelstorm, the administrator of the pd forums, suggested an improved algorithm for etrcalc, so I have posted etrcalc2.pd, which runs faster and also shows note number.
