Buying A Rochelle Concertina (Europe) in Buy & Sell Posted September 13, 2017 · Edited September 13, 2017 by TimTim Hi Nicolas, I suppose you've done your research on the Elise? Lots of interesting conversations, including one where a forum member explains the problem it might be the day you want to upgrade....and there are no "middle-range" concertinas available. I thought it was something rather crucial to consider... But then I am also curious about trying the Elise one day so... (by the way, I think the app can't mimic the instrument. When you have the concertina in your hands, there are so many elements your brain and your body register to make sense of it that I think it makes a huge difference. That is, you remember more easily and all. )  Sorry I'm in a hurry, just to add that there this other member Matthew Vanitas I think, who played an Elise for a good few years before upgrading so that too is good to know... aaarrhgh you've put the Elise back on my mind.
