(Bretton of this forum has even gone to the length of ordering an Abruzzi style "organetto" configured this way. Not sure how he got on with it though, since it apparently had no air button... Brett?)
Well now two men from Quebec - the excellent player André Bouchard and his brother Serge - have stepped forward with just such a box. It's a classic four-voice Québec or Cajun style one-row in D, same size, but with four extra notes - G#, c, d# and g#.
Quick tour of the box - YouTube clip.
Demonstration of a few tunes using the accidentals.
Although there are only four extra notes, there are four buttons to operate them instead of two. This was done so that the accidentals could be positioned sensibly - relative to the main row as they would be on a normal D/C# box (of which André Bouchard is an expert player).
They didn't put more than four extra notes because this couldn't be done without adopting a size larger than the standard one-row box, which they think would be less attractive to Québécois players.
They are priced at Cdn $2200.
The brothers are working on readying other designs too including, very possibly, a suggestion from me for my own particular dream box (compact 21-button C#/D in 10/11 configuration)
