I can, however, enter notes using a (MIDI) keyboard in a slow and rhythmless pace, and I can tap the correct rhythm on a single key. I'd love to combine these two inputs. Well, I think it would be a good idea to test this out before I start writing code to support it. You can do this by writing a melody that is all on one note. That is, enter a piece just by tapping on one note. Then look to see how much of the durations it got right, and see if accepting the correct ones and altering the wrong ones would be a practical entry method, ignoring the fact that all the notes are the same pitch. (You can, in any case add these over the top afterwards just by placing the cursor on the first note and playing the notes on the MIDI keyboard at your own pace). I'm sure the first thing you will want is to start playing with the AI - are you able to write simple Scheme? If so I will break this out for you to play with sooner rather than later.

As David points out in this thread, more sophisticated approaches would be needed to get something useful. I am very happy to provide the interface but don't expect to be working on the algorithm any time soon.

By hitting a MIDI keyboard key in the desired rhythm? Well, that is what is interesting: if you played in on a MIDI keyboard in perfect rhythm then you would be able to hit the accept key to accept the rhythm Denemo has computed. Indeed, if it was going to be perfect, you wouldn't need any second step, you could just go straight on to adding non-music features - repeat bar lines, rehearsal marks or WHY. What happens in practice is that the rhythm computed from your playing is full of errors and an artificial intelligence (AI) step is needed to get close to something that would be acceptable. (It has to be near perfect to make it worth giving to the user to check over, as fixing mistakes is far more costly than playing in the music). At the moment this AI step is the simplest possible, it goes through the durations that you played assigning them to the nearest note lengths using only whole-note 1/256th note and dotted versions of them (no triplet values have been entered in the table of durations). There are then two ways to go: Write some Scheme procedures to work out what the user likely wants, asking for the user to intervene where necessary Let the user start typing in the actual durations (on the numeric keypad) and learn from the first few what the likely durations of the succeeding notes are. So, once you have covered the rhythmic variety that you have in the passage, you would be able to go over to just hitting Return to accept Denemo's idea of the rhythm. This could include stuff like staccato markings, so that once you had shown it what you mean by a certain duration it could guess between say, a quarter note, a staccato quarter note and an eighth note followed by eighth note rest. At the moment, you can type in the duration on the numeric keypad or hit Return to accept the suggested duration. The note is played as you do this, so you can actually hear the piece as you go through it if you keep time. You have to enter rests, staccato markings etc. yourself. I will need to gain more experience of this system before deciding where to go next. The stuff is in Denemo's git now though, if folk like to experiment. The table of durations and the decision calculation using it is not currently available to Scheme, but if someone with Scheme wants to start experimenting it could be made available without problem, just ask. The system also works with imported MIDI files, which can have perfect rhythm if machine generated.

Another thing which will probably make instant compilation easier to realize is moving the music view to svg. On the long run this will lead to be able to graphically edit the result from a lilypond run, inserting the respective tweaks into the input files. Of course it will be a long way until that's near comprehensive, but if we start with tweaking slurs, fixing pitches or drawing spanners it will be more than a good start.

Re: Denemo-feedback
Hi Richard, sorry for the old version. I now installed Denemo 1.1.0 from the website. It can't use lilypond with it for some reason (it crashes when I want to print) but I can look around and compare. Many things have improved a lot: The sound plays nicely, the buttons show no artefacts, the menus are readable. I like the feature that one can click on the key signature to increase the sharps or flats. The look is still similar to Windows 95. On the website I saw something gnome-like but not in my installed version. Is that available? For my taste, there are too much buttons with a similar meaning. E.g. all the slur and bracket buttons could be simplified as Frescobaldi does: the slur spans the selected range of notes. Also, the buttons to insert a note and change the current note to a different duration duplicate things. Wouldn't it make sense to merge them (two different modes or a shift+click for changing). It would also be convenient to move the current note up or down with the up/down key (it moves only the cursor). I am still confused by the cursors, one | marking the point in time and a square marking the current note/pitch. It is sometimes green, sometimes blue. It is not clear to me how a new measure is started. At the beginning it worked (like in LP) automatically but later I had measures with more than 4 beats (coloured in read) and the automatic bar line was missing. The menus are very full which is probably a result of putting everything in that is possible (which is good to have). But an intelligent reduction would be needed (imho). E.g. for slurs you have to search a while: Notes/Rests Markings Slurs Begin slur The menues are difficult to browser, because the tooltip/hint is often very large and covers the menu. What is the reason for not chosing LP shortcuts for input: (=start slur, )=end it, 8=eigth note, r=rest etc. It would train people a bit to this well designed representation. , works to go down one octave, but ' does not go up. The dot button and the accidental buttons as well as key signatures and clefs work nicely. I am still not convinced but it is definitely in a better state and there were many improvements.

with a similar meaning. E.g.
all the slur and bracket buttons could be simplified as Frescobaldi
does: the slur spans the selected range of notes.
The customizability of Denemo means that such a feature is easily added
by the sort of user that customizes. I did even create such
mouse-shortcuts some years ago, but found that for practical purposes
hitting 7 to start a slur and then 8 to extend and 9 to reduce the slur
was just so much quicker. (You set your own custom shortcuts by right
clicking on the menu item).
Also, the buttons to
insert a note and change the current note to a different duration
duplicate things. Wouldn't it make sense to merge them (two different
modes
ah, yes, Denemo had modes at one time too. Modal programs are pretty
universally decried for tripping you up.
or a shift+click for changing).
The combinations in use by default are Digit, Shift-Digit and Letter,
Shift-Letter for durations and note names respectively, for
inserting/changing respectively.
It would also be convenient to
move the current note up or down with the up/down key (it moves only the
cursor).
You could set that up but then you would need a different key press to
move the cursor rather than the note.
I believe there is still a mouse-drag of notes up and down (setting the
caps lock I think), but I wonder how much it is used.
Mouse gestures can be customized by the user, but then they get in the
way of more serious use (no one seriously enters music using a mouse -
it is unbelievably slow).
That was one of the reasons for that Profile dialog that was the first
thing in the old 0.9.6 - if you chose mouse user you would get
something like that. LilyPond User on the other hand would get more
familiar short cuts and, more importantly, would get things like \repeat
volta 2 { . } which to a user unaware of LilyPond is quite baffling
- they just want to put :| in the score.
I am still confused by the cursors, one | marking the point in time and
a square marking the current note/pitch. It is sometimes green,
sometimes blue.
yes, the colors reflect the fill of the bar - this is explained in that
first big tooltip on the main display area I think.
It is not clear to me how a new measure is started. At the beginning it
worked (like in LP) automatically but later I had measures with more
than 4 beats (coloured in read) and the automatic bar line was missing.
yes, Denemo does not stop you overfilling a bar if you want, but
LilyPond will not typeset them unless you issue the appropriate command.
If you enter notes in the middle of the bar Denemo will not bump other
notes into the next bar - usually that makes no sense, and would be very
annoying if you were adding notes just temporarily prior to deleting
some others - after all, it could hardly go and get them back again.
If such is a normal thing in your use you would want to set a short cut
on the Split the bar at the cursor command. You just select the menu
item and press the key you want as a short cut.
The menus are very full which is probably a result of putting everything
in that is possible
not everything by several orders of magnitude, but most things that
Denemo has are there, just a few are hidden (e.g. LilyPond style
repeats, because a novice would get in a mess).

reduction would be needed (imho). E.g. for slurs you have to search a
