Can I play a hymn on a midi keyboard, and have it show up in Noteworthy Composer? I would want half notes entered as half notes, quarters as quarters, etc. What I am after is transposing hymns without going through all of the steps I have to go through now, entering notes from scratch via the computer keyboard.
Also, if this is possible, which midi keyboard would be the best purchase?
Short answer = yes.
Long answer is there are a few things you need to do. To get correct note lengths you need to record against a "click track" - this is a file NWC is playing while you record.
To save some effort on my part and give you some reading exercise ;) I've searched out a few links for you. These are not exhaustive nor in any particular order...
