The Borromean Knot


an experiment with the bell on speaker
what mechanism will move the valves? lots of trials, experiments.
getting a feel for micro-changes in half-valving


feedback trio (w/luc d̦bereiner, ludvig elblaus Рmarch 2022) this uses the feedback earbuds, attached to the quad trumpet.

Signal flow, inputs:

Rather than the traditional 1 input = 1 output model, with a few quick re-arrangements of tubing the trumpet can instead be conceived as a matrix mixer (4 inputs, 4 outputs, variable shifting) with subtle movements of the valves influencing signal flow/channel assignments.
