Nice one, I like it! I have a simmilar instrument, melodica, with piano keyboard
Never tell an accordina player that a melodica is similar! (It's a sensitive topic, especially since an accordina costs about 10x what a melodica costs, if not more.)
For a while there were also accordinas with piano keyboard but they were too large to be really usable. Borel lever made them. Marcel Dreux who makes Borel-clones also never made them (only said he had plans to do so)...
I'm not saying a melodica is a bad instrument or just a toy, but an accordina is quite different and so is its tone.
