HV Synth Design has released Total Trumpet, a new VST instrument plug-in for Windows featuring very natural sounding trumpet sounds, including overblowing. It costs $79.

Controls:

• Breath Pressure: via MIDI learn you can choose the CC you prefer. Here you can also set a threshold for more or less breath pressure.
• Attack for 'blowing' explosive attacks.
• Player Lips: Sometimes the lips are audible, a kind of short thrill. There are two knobs: Amount (MIDI learn) and duration of the lip thrill.
• Instability (long notes always have some instability).
• Attack noise: this also causes some instability when you play long notes.
• Flutter Tongue: this is done with a rapid up and down movement of the tongue (MIDI learn).
• Portamento: you can choose between MIDI learn and velocity.
• Timbre: you can select two timbres or the Harmon mute.
• Note-to-note transition: When the note-to-note transition is audible (legato), then this is also imperfect playing, Pressing a piston, when another one is not released in time.
• Damping: with this knob you can alter the bore structure, and so alter the timbre (MIDI learn).
• 4 stage EQ.
• Harmonics: With this knob you can add lots of extra harmonics.
• Tuning.
• Pitch and amplitude vibrato via aftertouch or MIDI learn.
• Volume.
• Overblowing has to be done with the Pitch Wheel. Overblowing a trumpet while you start on a C, then you always hear the harmonic series C E G Bb (C), but when you alter the bore (Damping), you get other series and effects.
• Muting: There are two knobs: Mute1 and Mute2. Experiment with them. MIDI learn for creating 'moving' mutes.
• Stem for making the famous wah-wah effect on the Harmon mute.
• Voices. Here here you can select the number of voices. There is also a knob for stereo spread.
