One result of this a timbre which sounds more like a saxophone than a clarinet. You can hear this in Linsey's Cylisax.

Also, instruments with a cylindrical bore and are closed at one end aren't able to support the second harmonic. The reason for this is too complicated for me to grasp.

Since the Venova is open at both ends, another result of the second tube is that it overblows (much more conveniently) at the octave.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
