Still getting my head around what this does for me - but is there a way to add a 30 button G/D Anglo layout to it?

This is what I've developed for my students. Any use to you?

Just looking at this thread for the first time. Thank you so much for your hard work Chris - a tremendous resource! This will be VERY helpful to me in trying to advance beyond the push it & hope for the best stage!   (:)

can you please post the note scheme here as  separate push and pull diagrams. Each can be a block for the two hands

push
x x x x    x x x x
x x x x    x x x x
x x x x    x x x x

pull
x x x x    x x x x
x x x x    x x x x
x x x x    x x x x

Assuming this is how the rows go? I used to play anglo and can voice it for you. Assume you would like you display rows curved as per steve. The webpage will find ANY chord if the instrument can do it, and some of the partials "work" too. i think 30 anglo happiest in its own keys, but friend Jan, of Gent plays proper jazz on his, and last december we were in G minor. So it's there …

Thanks Steve - I am trying to extend my new and imperfect left hand skills on the melodeon towards my concertina. As such I am clearly not yet able to fully recognise the value of the tool, so please forgive my ignorance.
Thanks also to Chris for taking the time to develop it, of course  (:) kind of goes without saying, but perhaps it shouldn't.

Moving on the box in question, which a Marcus.  :||: Curves entirely optional!

Push
B  E  G# E  D#      G# E  D# G# C        G# are 3, 4 and 5 on a Petersen tuner
G  D  G  B  D         G  B  D  G  B
F# A  D  F# A       D  F# A  D  F#

Pull
C  F  A# D  F       A# D  F  A# E
D  F# A  C  E      F#  A  C  E  F#
G  C# E G  B       C# E  G  B  C#

Try this (indented but not curved)

Code: [Select]
→→ ¹B  ¹E  ¹G♯ ²E  ²D♯ →→ ²G♯ ³E  ³D♯ ³G♯ *C
→ ºG  ¹D  ¹G  ²B  ²D →→→→ ²G  ³B  ³D  ³G  *B
¹F♯ ²A  ²D  ²F♯ ³A → push → ³D  ³F♯ *A  *D  *F♯
=
→→ ¹C  ¹F  ²A♯ ²D  ²F →→ ³A♯ ³D  ³F  *A♯ *E
→ ¹D  ¹F♯ ²A  ²C  ²E →→→→ ²F♯  ³A  ³C  ³E ³F♯
¹G  ²C♯ ²E  ²G  ³B → pull →  ³C♯ ³E  ³G  *B  *C♯

The code converts prefix voicing octaves to suffixes (looks tidier). The range is dictated by that low G 2nd row. Rodec octaves start on "A" and your "G" is a tone below that, so has to be on octave 0.

To explain the "*"'s:  There is no suffix 4 in most typesets, but nor is such a high note very meaningful musically. Any note above octave 3 shows as "*" and voices in octave 4. The actual notes sounding when you click the icons are off my Gaillard

If it sounds too low  you can toggle higher octave (on - Control -- row). Better, edit the rodec in the box. Delete eg "¹G" and replace with 2G, etc etc - press the [!!] button to rebuild. If you want different indents use ">" for an "→" arrow - they convert too.

You can then save the text rodec on any (standard now) UTF-8 text medium (such as "melodeon.net")  ;)  (Yes, Clive, I was going to do a 'Mediæval' ASCII option ... )

Once you are happy with it I can plumb it in as a pre-set. This layout seems pretty common.
