@wwoodard8 Forgot to mention - it works great with absorbing water. No burbling sounds, dripping etc...

@Clint Nice. I am a "wet player" too :)
In the video you seem to imply you just leave the insert in all the time. Do you ever have to pull it out to dry?

I've also been playing with this idea and am using this stuff from Amazon: https://www.amazon.com/gp/product/B08ZHZS1W6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

The box is much cheaper than your alternative ($14). My wife, the nurse, showed me this - normally used for wound dressing (!) But each insert gets soaked, so I change once per day.

I cut off a piece, twist into a tube and insert.

(It's amazing how this thing in the mouthpiece makes no appreciable effect on the wind resistance. Can't do that so easily with regular wind instruments! It's fun to ignore the laws of physics... :)

Wow, Clint, you are reading my mind!

What exactly are your symptoms? In other words, what problems are being caused?

For my part, I'll notice a bubbling sensation. It's weird, but it doesn't seem to affect the tone in any way. Because of that I suspect the problem is happening at the bottom tube plug - water gathers and fills the little hole of the plug.

What I've done in this case is to always have two plugs and two mouthpieces and swap them out when one gets too wet. But I'm panicked that I'll drop the tube plug and it will get lost on a dark stage!

I mean, this kind of thing has always been a problem with wind players (as I'm sure you know), Usually, people don't mind taking a break while someone swabs out their instrument.

Would also be worried about blowing the thing down the tube, but "nary a drop" sounds really good :)

Search "hydrophilic" on Amazon and you get something else that might work - here

For those of you who have come to the Sylphyo from other wind instruments, what do you find are the differences in the way you provide breath support?

Is it as generally important on the Sylphyo as it is on "real" wind instruments? In what ways is it different? Do you have any wind synth specific breath support exercises you do?

Thanks!

@Gromit Ah, well, interesting. I would really like a bite controller :)

Wait, what? What is this interesting "dynamic mouthpiece" of which you speak? :)

@Clint Ah, now this is good info! I'll try the velocity as 1. (BTW, why 1? My assumption is that synths built especially for wind synths will just totally ignore velocity...)

@Clint Well, looks like the "re-pair" repaired my problem :) Everything is flowing smoothly now!
