This is how and why musicians and instrument builders collaborated in the 19th century and earlier. Many years ago I made a movable key that could slide back and forth in order to study its position in relation to intonation. This was long before computers and video. It was a fun experiment.
Marcus Wuersch is incorrect when he asserts that the keyed trumpet is the first member of the brass family (not counting the trombone) to be capable of playing chromatically. The Serpent, dating from 1590, is a brass family instrument capable of chromatic playing.
Konrad Burri appears to fall into the eccentric instrument inventor-mad scientist-evangelist category. On a mad mission to achieve something that probably nobody wants or needs, and making all sorts of outlandish claims in the process, e.g. 'As soon as anything is attached to a brass instrument it becomes unusable' (gee, I guess then that all the wonderful playing/sounding modern brass instruments (which all have lots of things soldered/mounted to them) must be a figment of the worlds' imagination, and 'touching the body of a brass instrument is like touching a vibrating string'....well, no, the string vibrates and the AIR INSIDE a brass instrument vibrates....his is an absurd claim.
Superb! Nice to see the better instrument that can be made on the evolutionary path of the keyed trumpet. Much nicer timbre than a valve trumpet.

You said "playinf with piano." What about with a pipe organ? Woth proper regisration, the organist can approximqte the tambres of the organ.
How iscthis diffwrent from rhe Anglo-Amercan keyed bugle?
