"Pan whistle" connecting multiple whistles

[hatao]

The Pan whistle is a newly developed device created using a 3D printer. The connectors are designed with a diameter of 1mm increments, allowing for the attachment of whistles of various sizes, from tin whistles to low whistles. Additionally, by connecting the mouthpiece, there is no air leakage from the gaps when playing multiple whistles simultaneously.

By using this device, you can expand the range of the tin whistle, freely transpose, and explore new possibilities in playing.

Here, soprano D and alto A pipes have been connected.

Thats very nice.
I have seen some other whistle-like instruments, that was a bit like it. But not anything like this.
I imagine it is somehing that takes quite some time to get used to.
Doesn't it feel like the whistle you are not playing, is in the way and hinder a bit of fingermovement?

To quickly swith between whistles, is very nice. I can see som good possibilities in this.
