A great project the creates a MIDI controlled slide trombone. Here’s more from iSax Laboratories:
The original idea was to produce a MIDI controlled music machine that could play any song. It was however extremely difficult to control it reliably. When a human trombone player produces a tone it is a combination of lip tension, pressure against the mouthpiece, airflow, air pressure, resonance in the mouth and probably some other variables. The lip part proved too hard to recreate. The machines will not take over the trombone plying profession any time soon and I’m left with an over engineered noise machine.
