Thank you for your description of the melodica. I appreciate. Your explainations that you give on this site are good and clear. Yesterday, I plaid a bit with my Suzuki. I can confirme you this is a Study32. They are 2 things I don’t like about this melodica: the carrying case and the mouth piece. Because I can’t see the case and the shape of the melodica is moulded inside, I have difficulty to put the pieces in the exact sense as it has to go. I don’t have this problem with my Performer 37’s case. It’s much easier to put it inside. Sometimes, I’m not able to close the Suzuki case. Is the Yamaha carrying case similar to the Suzuki Study32?
