Marc is correct; that's a Roland Aerophone. Someone sent me a video of someone playing one, years ago, and said I should get one. It's a neat idea; a MIDI controller that's not a keyboard but based on a scaled-down Boehm system. The Boehm system is used on all modern woodwinds and basically means that if you can play the flute, you can mostly play the saxophone, oboe, and clarinet as well, because the fingering patterns are all the same. That's the really TL;DR version. Each individual instrument has its differences, hence the "mostly". Anyway, driving a synth, sampler, or anything else you might want to drive with a keyboard but using a woodwind-like controller would be fun.
It's a neat idea, and I've never played one, but it seems like it would feel very restricting. It doesn't have
all the keys, just most of them, and after 50 years of playing winds and muscle memory, I'd think I'd have issues. Given unlimited funds, I'd probably opt for a
Yamaha Digital Saxophone or even hunt down an old Lyricon instead.
