Bore

Functionality

Bore couples nonlinear reed flow to a damped, pitch-tuned waveguide. Pressure changes reed drive and loop sustain, Embouchure moves the reed resonance relative to the bore, Bell changes feedback damping, and Breath adds filtered noise. Reed Instability adds turbulent-flow noise and slow lip flutter. Register Capture couples more of the nonlinear reed airflow into the bore; high pressure and tighter embouchure can let an upper mode catch without directly transposing the played note. It is a compact physical sound-design model, not a calibrated trumpet simulation. There are eight MIDI voices, an Attack/Release envelope, velocity sensitivity and a channel filter.

CC 1-6 control Pressure, Embouchure, Bell, Breath, Reed Instability and Register Capture; CC 7 controls Level. The core tests and VST3 build pass. Listening and host save/reopen validation remain pending.
