[André Sant’Anna]

Yes. It depends on the weather like I said, but every 20 minutes on average when I’m playing.
After some time playing, the water that condenses inside the tube starts bubbling when I blow and when it happens I know I need to empty it. All that water would be inside the melodica! When it bubbles, I disconnect the tube and blow it hard a few times to empty it so I can continue playing. It’s quick.

Since you’re a melodica builder, I think it’s a good idea to make a longer path to the reeds so the water can condense before it gets there. I think Oscar did that, as I noticed there are some “curves” in his models’ mouthpieces (Diamanté Vox, I think). Also, I assume that if the material before the reeds is made of some kind of metal, the water tends to condense there first. I would like to test it with the Suzuki Andes mouthpiece, as it is made of metal.
