Hello again soulsaver,
Just felt the urge to diversify, and have heard a lot of very nice Italian style musette tunes being played on PAs. As I grow older its seems that I am beginning to appreciate the more laid back legato sounds of the Italian PA vs the French musette CBA style.
Ideally I would take my lottery winnings to Italy and get a top of the range Italian made sistema francese CBA box, maybe a Stocco or a ByMarco. I don't think I would buy another French CBA, as I find them more difficult to play in terms of button accuracy. I have an Italian sistema francese CBA box but it is only 3 voice with 2 voice vibrato. The buttons are slightly larger and wider spaced than on my French instruments, and I personally find that the Italian buttons seem to suit my hand better. This may be something to consider if you finally decide to change over. French CBAs need greater accuracy so that you don't "foul" a button adjacent to the one you want to play. The transition from piano keys to Italian buttons would in my opinion be easier than French buttons. Italian CBAs are on average 1cm longer along a typical 16 treble button row than their French counterparts, which would not perhaps be much of an issue, unless like me you have both types of instrument.
As I seem to have mislaid that winning lottery ticket, cost is also a major factor. At my age as an amateur player fast approaching OAP status, I simply cannot justify the cost of a new or decent secondhand CBA, as they are getting harder and harder to find in the UK these days, and when they do turn up they are often sold at exorbitant prices. Another downside is that in almost 100% of cases the seller proudly proclaims them as "great for Scottish music". I have nothing against Scottish music or players, but it is just not my cup of tea. A lot of players with very strong Scottish musette tuned instruments play French, Italian, Alpine, and any other musette style tunes. Hats off to them but that Scottish musette sound grates on my ears. So does the French pur musette, and I abandoned it years ago in favour of the more mellow two voice "celeste" tuning. The Italian musette tuning is more mellow and easier on my old ears.
I can buy a decent s/h top Italian brand PA 4 voice with musette, for under a grand. I wouldn't even consider most CBAs I've seen for a similar price.
I'm not going to get involved with different musette tunings, as it is not something I know much about. However, if it was actually the case that one musette tuning was enough to cater for all styles, Roland wouldn't have bothered to provide the facility to change the settings.
That said, some of you may remember that my first post concerned Rolands vs French midi systems. If I ultimately decide that PA is just pie in the sky then I might have to reconsider a digital accordion, and it would be CBA. If I take too long deliberating it might not be a Roland though.
