Thanks for the great music Henrik. It shows what you can do with your ''strap system''. Perhaps I am missing something but why can't I see the regular 48 (or 56) button design in your EC?
I will try to put some music of mine on YouTube in the near future. All this concertina (and non concertina) chitchat on Concertinanet is great, but it is the music made by all of us that really count. I am always interested in how people play, no matter if they are beginners or 30 years experience pros. So the more music made available the better. Although I know I should give a good example myself

Très bon, merci, Hermann -
In the shower this morning I realized that I hadn't listed all the
differences between my instrument and a standard EC.
One of them is of course the number of buttons:
The mini Stagi, which started all this has 18 buttons ans that's a bit on the low side

.
So I sat down and played all tunes I could think off, to find the coverage I needed. And I
glued little paper dots on the sides to mark the missing buttons and ended with 27. So a
lot of bs and #s are missing, hence the peculiar look of the layout. Should have been 28...
In my well-plannedness, I forgot that the position of the high C was in the "hole part" of
the Stagi's fretwork, so there was no paper dot. And since considerable time went by before
I actually started making serious drawings, I only took one look at the Stagi and said: "Right,
that's buttons I'll need" and started drawing. Much later, I realized the mistake
Anyway - the fact that all the buttons up there in the eternal snow are gone, brings us to the
next difference: the whole cluster of buttons are moved upwards, approximately the vertical
distance between the buttons. This facilitates reaching lower notes.
Finally, the thumbstrap. On a standard EC, I will place the end joint my of my thumbs in the
straps (again to reach the lows). And my thumbs don't like that, probably due to the playing
style - I use the bellows a lot, and the pull, with the thumbs in that position definitely don't
agree with me. But the thumbstrap is still there, yes?
The new thumbstrap is only half the width of a standard strap and it is positioned on the
instrument so that the thumb is meant to go all the way in. It acts merely as a guide, there
is no strain on the thumbs - all the pulling force is on the handstraps.
So, to summarize all the changes:
1) Wider spacing between buttons, asymmetrical: more space horizontally
2) Lots of bs and #s are removed (also the need for space was considered - accordion reeds need more room)
3) The button cluster is offset one button upwards
4) The buttons go all the way down (I can feel the hole on the finger tip)
5) A handsrest, angled 15 degrees
6) A handstrap, coming up between the thumb and index finger, going back almost in the corner hand/arm
7) A thumbstrap, half width, positioned so the thumb goes all the way through
That's all!
