I am currently enhancing HARMONY to allow users to play tunes into the program (and onto score) using a MIDI keyboard plugged into the PC.

This is currently restricted to melody only, and in step time (I.e. all notes the same length). I can detect the actual note time, but it seems very difficult to play all notes at the correct length, even when a range of values is allowed.

Before I go too far down this path, I would like to know if this facility is something which people would find useful.
