Thank you very much for your warm welcomes and kind comments. You can't imagine how much I appreciate your words.

Jim,
Answering your question on how I use my computer keyboard to create my melodies in BIAB:
I find the notes for the tune on my acoustic guitar and "transport" them, one by one, to the piano roll. I use ctrl-shift-leftclick to insert the notes one after another, and then I alter them as required by the tune, using the options that appear when you hover your mouse over the notes; for example, I make them longer (i.e., wider) or shorter, or move them up or down as necessary. I also left-click on the notes to verify that they sound as expected.
After I've completed a few bars, I usually copy and paste (duplicate) the segment into the following bars, so I don't need to start from scratch creating notes every time (I just need to move them around). When I have at least 8 or 16 bars done, I start searching for a BIAB style that most closely resembles the melody that I have in my head, and adjust the notes as necessary.
Then, I continue creating the rest of the bars until I have a complete draft of my song. And finally, I go back and adjust the individual notes, over and over again, until it all sounds as I envisioned it. It's not a complex process per-se, but labor intensive indeed. A true labor of love.
I do this for all melody parts, and sometime for other instruments as well. For example, that's how I create the bass part in Love It Or Leave It, where I needed the bass to play a determined part.
Hope I knew how to explain myself, Jim. Please don't hesitate to ask if you have any more questions.

Thanks again to you guys and gals, and to everyone else who kindly took their time to listening to my songs.
Al
