Requst

Config menu get bigger and bigger. We need to improve usabliity

Approach

1. rearrange config menu
2. add hints to config menu

Variant endings should be rendered as such

Problem: In case a note has no synchline to another voice it is hard to read.

Request: Create a flowline to up to the most recent note in the current voice which has a synchline.
Call the thing a "subflowline"; make the subflowline selectable.
Make the subflowlines light grey (or dense dotted)

• gives noise if song starts with rests
• stops after the last note of last voice

Request

Triplets somtimes look ugly, in particular if they are not monotoneous.

Approach

1. Let user drag the triplet "3" and compute the Controlpoints of the Bezier-curve accordingly.
2. Analyze all pitches of the triplet and optimize the rendition.
3. use big curly braces for triplets instead of Bezier-Curves
4. ...

Request

Some users do not want to store in Dropbox. For those we should have the way to save locally as ZIP-Download.

Approach

Reactivate the code for this.

Request

For some configurations Zupfnoter adds an "x" as key. But it could find the next free key.

Request

We should automatically create notes how to count:

Solution approach

1. Configuration can turn countnotes on/off per voice:
   countnotes [1,2,3]
2. Inline-instruction to turn countnotes on/of within a sequence in the voice. Alternatively configure it with notebound-Annotations
3. Use small anntoations for countnotes
4. count in denominator of Q:
5. count half of denominator with an 'e' e.g. 1 e 2 e; or 1 e u e 2 e u e
6. compute the position of the annotation based on previous / next note

Request

in testcase Rest.abc:

note the configuration

      "layout"      : {
        "grid"         : false,
        "ELLIPSE_SIZE" : [4, 2],
        "REST_SIZE"    : [10, 5],
        "LINE_MEDIUM"  : 0.3,
        "LINE_THICK"   : 0.5,
        "Y_SCALE"      : 15

Hi, I am very impressed with your work on zupfnoter.
I understand that you use abc2svg for rendering your tunes.
What i don't understand completely is how you get the musical structure in your app, pitches times and positions in the score. I looked at abc2svg myself but I couldn find a way to get tune data, for example for playing it and animating notes. I would be very thankfull if you could give me some pointers!

Request

• When starting Zupfnoter on MS-Edge it claims that 'uicontroller' is not defined.
• after passing the controller directly to init_w2ui() instead of using a global variable it does not claim missing uicontroller. But it is not initialized properly.
• it throws a lot of syntax errors
• it does not render text with hyphens in SVG https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/5432639/

solution

• use chrome :-)
• raise a waring if running on edge
• try to nail down all that stuff

Request

1. Ace Snippet should provide a full blown working configuration covering 80% case
2. This configuration shall be easy to adapt.

approach

• Inject a snippet with a reasonable "0" - Configuration with proper positioning of legend and page title
• provide a snippet with a full configuration

The abc - editor should have a menu item "paste lyrics".

This would take the text in Clipborard and prepend it with "W" and insert it in a new line.

solution approach

1. load the lyrics editor when activating the lyrics tab
2. update the abc-editor on every change in the lyrics tab

When printing on A3 sheets the G, is cut because of the drawing area limitation of the printer.

We should add an option to shift these notes on A3.

request

up to now unisons are connected to their first not. When importing musicxml it is often the case that unisons are noted from low to high while the melody is often in the highest note an unison.

Solution

simple and pragmatic

let unisons be connected to their last note

complete solution

make it configuiable by by voices

uninson_proxy : first | last | highest | lowest

Request

we should have some support for positioning of lyrics etc.

1. allow to move them on the harppreview
2. report the new coordinates
3. backannotate the coordinates to the abc source

Solution approach

1. implement draggable in raphael-engine.rb (see http://wesleytodd.com/2013/4/drag-n-drop-in-raphael-js.html)
2. reorganize configuration such that we no longer use arrays for lyrics and sheetnotes
3. implement an on the fly migration of configuration
4. backannotate the coordinates via confstack

Request

if a repeated section ends with a rest, the pitch of the rest shall not be the one of next note. This is because we do not continue to play at the next note but at the beginning of the repetition.

Therefore it is irritating to place the rest adjacent to the net note.

Solution

1. set the pitch to the one of the previous note in case a repetition ends with a rest.
2. investigate,
   • if the pitch of rests shall always be the one of the previous note.
   • behavior on variant endings
3. refactor handling of pitch in rests, @previous_note, prev_pitch etc.

Status

1. does not work if there are more than one rests at the end of the repeated section.
2. does not work properly in case of variant ending

I guess the whole thing needs to be reworked. Even the code is hard to understand.

Request

Some users do not like the pure web based approach. They request a Desktop version.

Solution Approach

• Create a desktop with electron.io

Status

• initial attempt had problems with jquery (vitmalina/w2ui#1265)

Notebound annotation should also inherit from View 0. this does not work

M:4/4
K:Ab

C D =D E |
C D z =D E |

W: despite of the rest, both measures shall be the same

but they don't :-)

There is a way to express the the tempi of music by a special language for example:

1,2,3,4 => ta o a o
12 => ta o
1 => ta ta ta ta
1 2 u 3 u 4 u => ta ti ti ti ti ti

If a chord is entered, it has its own Synchline, but is not connected to the other voices.
Please connect the chord with a Synchline to the voice as well

Request

in testcase Rest.abc:

Request

There are some people requesting a German version

Solution approach

• use w2uitils.locale / w2utils.lang http://w2ui.com/web/docs/w2utils.lang
• store the desired languate in systemstatus
• detect language by `navigator.language``
• do the translation in
  • logger
  • abc2svg - need help from Jef
• mimic I18n.t("foo") for ruby strings

Status

• Localization of w2ui based UI done
• localization of abc2svg error messages done
• localization of parameter help open

Request

• As of now Zupfnoter shows the demo tune only if

  • it is invoked the very first time or
  • user enters "demo" in console

  when Demo tune is loaded the content of localstore is desctroyed. User looses his tune if it was not saved before

• There should be more Demos to be invoked from the Help menu

• It should be possible to create a link which directly opens a tune in Zupfnoter similar to opalrb.org/try

Solution approach

1. Provide URL-Parameters to load demos
   /?load=...&mode=demo
2. if demos are loaded, make them readonly, at least do not store them in localstore
3. provide a share button which crates a link with a compressed url

Request

if a repetition starts with an upbeat, the first note does get a measure bar.

Solution approach

investigate the first measure of upbeat and draw measure bar only if it is a full measure

As we now have multi-level configuration, we should provide proper defaults for the position.

1. Modell Standard
   • top right
   • top left
   • bottom right
   • bottom left
2. Modell Solo
   • top right
   • top left
   • bottom right
   • bottom left

Problem

We had the situation, that a piece was created on Mac, the copied to Windows and the user added German text with Umlauts on Windows. Zupfnoter then reported a "BUG".

As a pity, I cannot reproduce this on my machine.

Solution Approach

Investigate the character encoding of the abc text.

This is with ELLIPSE_SIZE = 0.5. It is easy to see that the jumpline starts too far off.

Also punctuations and mesures. Seem to have the same cause as #16

Request

There should be a user manual, in particular for German users as Zupfnoter UI is english

We could place 5 digits of SHA on the sheet to idenfify sheets steming from the same ABC

Request

There should be an option allowing to print the note names on top/bottom.

Solution approach

1. call it "scalebar"

2. make it configurable

   "scalebar": {
                    "text":  "G G# A A# B C C# D D# E F F#",
                    "vpos":  [6, 290],
                    "style": "small"
                  }

Some Decorations should be supported:

• Active in all voices - everything about speed, volume and sequence

  • !fermata!
  • statccato
  • !fine! all voices
  • !segno! 2 ornate s-like symbols separated by a diagonal line
  • !coda! a ring with a cross in it
  • !D.S.! the letters D.S. (=Da Segno)
  • !D.S.alcoda! the words "D.S. al coda"
  • !D.S.alfine! the words "D.S. al fine"
  • !D.C.! the letters D.C. (=either Da Coda or Da Capo)
  • !D.C.alcoda! the words "D.C. al coda"
  • !D.C.alfine!
  • !piano!
  • f, ff, fff, p, p, ppp

• move to before note

  • the closing part of cresc and dmiini

• others

• !arpeggio!

Note that some decroations shall be active in all voices

See testcase 3000

Request

• get rid of the red progress indicator
• do a render before play if necessary

When shifting a note with "^>", it does not shift the adjacing measure bar

Request

in some cases it is too complex to represent repetitions by jumplines. Please implement an alternative representation

Solution approach

• represent repetitions by annotations |: resp :|
• compute the default position by the pitch of the note before/after such that the flowline does not cross the repetition sign
• make the marks such that the colons are on the note site (den Noten zugewandt)
• make parts on repetition begin and repetition end
• configure it like

        "repeatbars"   : {
          "voices" : [],
          "begin"  : {"pos": [-5, -3], "text": "|:", "style": "bold"},
          "end"    : {"pos": [3, -3], "text": ":|", "style": "bold"}
        }

ctrl - R - Render
ctrl - P - Play
ctrl - S - save in dropbox

Request

Play should use Harp sound

Approach

1. use https://www.npmjs.com/package/soundfont-player
2. create a soundfont of a Zauberharfe from an mp3 recording

Request

dragging of notebound anntoations is grown somehow, but we have to clanup strategy and implementation:

• consistent configuration approach such that volatile keys are not repeated

  notebound.voice.note-id.class.pos
  

  With this approach

  • rearrangement of voices can be easily reconfigured by changing the "voice" key
  • If note-id occurs only once

• limit to particular voice. Up to now the same note-id in different voices synchronized the result of the dragging. This is not practicable

Solution approach

• apply the approach to annotations, partnotes, variant endings
• countnotes are handled separately
  • ability to reset those in one shot
  • they are positioned based on time, not based on note-id
  • the annotations are computed in layout phase not in transformation phase

jumpline still goes to the one specified in Synchpoints
all others are represetned by the one
specified in layout_accord

This is not dry

Furtheron, if a repretiion starts with a unison, we get an error because prev_pitch is not defined for Flowline

Request

provide a consistent way for feedback to user. Console was intended as such but is not accepted by users.

Solution approach

add a status line at the very bottom of the screen showing:

1. Dropbox status (done)
2. Cursor-Position in ace (done)
3. ace token info 8done)
4. information about the current element when hovering over it (done)
   • confkey
   • ...
5. storage status
6. demo mode

...

Request

1. Play-Button shall decide what to play:
   • if one note is selected - play_selction_ff
   • if more than one note is selected - play selection
   • if nothing is selected play from the beginning
2. improve selection such that shift click on a not also selects the range
