Current Yamaha and Suzuki metal tray melodicas are not likely to arrive noticeably out of tune, Noa. But I have tuned them and this will be necessary eventually, as Aaron has observed, if you are finicky about tuning. These models are typically reasonably well in tune with themselves but sharp, closer to A=442 than to A=440. I tune some down from the vicinity of 442 or 443 to 440 or 441. The more tning you do, the quicker it goes, especially once you have it to the standard you want.
