I’ve tried e few Audio to Midi plugins not long ago, with the recorder, but they all suffer from the same problem: lagging! There’s a clear lag even with the Sonus G2M, as you can see when the dude sings. I don’t think that’s the way to go…

Maybe I’m wrong, but I don’t think there’s enough room in a standard melodica to allow for a DIY solution, that’s why I was hoping for a solution from some major manufacturer… But I see no interest so far from our fellow members…
