In article <3978@pt.cs.cmu.edu> ralphw@ius3.ius.cs.cmu.edu (Ralph Hyre) quotes me out of context, then follows with his own comment as follows: >>She also composes, using a music-score processor. she uses the mouse in >>one hand to place notes on staves, and the keyboard under the other to >>select which kind of note the mouse will leave. >Why not use a real piano-style keyboard for this? It's hard to get more >natural, unless you have no piano experience. or a MIDI guitar, or >anything MIDI interfaceable that you can easily attach to most >computers. For editing, it should be sufficient to point at the >note with the mouse and change it. If you'd bothered to read all of my original posting you'll see that that tool is available to her, but she chooses not to use it for that specific task. Creating sheet music is too different from creating music. When you create sheet music, you are interested specifically in how the symbols look on the page. It is much easier to directly put the symbols where you want them than it is to play a note, and hope it goes in the rght spot. The vertical placment is solely a function of pitch, but the horizonatal placement is a function of the typesetting requirements of all the verses of lyrics and also of esthetics. The time domain data is much faster to specify with the typewriter keyboard than it is in the time domain itself. With the mouse and typewriter keyboard system you can get whole notes on the page much faster than you would play them. (You could fix this by adding a foot pedal, that adjusted an on-screen display of tempo.) Note, I've directed follow ups to the user interface group.

New York: ACM Press, 1988. Which was recently published and made available from the ACM. It is the edited proceedings of the January 1986 conference of the same name, which brought together many of the people who stubbornly persisted in developing personal workstations since the 1950s against the grain of the computer industry. It is fascinating! Unfortunately, the banquet address by Alan Kay, which is available on videotape, was not adapted into an essay; Kay seems to have forsaken the discipline required to communicate ideas in an essay. This is a shame, for Alan Kay has had a profound impact on the technology and has a lot of valuable things to say. Also, while I'm writing, the original discussion was about the desktop metaphor -- readers may be interested in the following short piece: Malone, Thomas W. ``How Do People Organize Their Desks? Implications for the Design of Office Information Systems''. @ux(ACM Transactions on Office Information Systems), January 1983. Cheers, -Ittai
