I like to know that if i can play back a quater tone flat or sharp using N.W composer shareware version
It can be done using pitch bends, but it is not easy. Details can be found at https://forum.noteworthycomposer.com/?topic=407.
Also check a suite of programs by NWC enthusiast Fred Nachbaur, which diddle around with several aspects of harmony and temperament in MIDI. They can be found on the Noteworthy Scriptorium (http://nwc-scriptorium.org/) (a user based archive of many things NWC).
Fred's stuff is at
