Hello! Here is an experimental synthesizer that mimics a Bb clarinet. It creates sounds using waveguide physical modeling synthesis.

It’s not polished, but a work in progress.

It is monophonic and is meant to be played using a wind or breath controller on CC #2 (although other CC’s can be selected). The sample rate must be 44.1 or 48.0 kHz. Internally, the model is 4x oversampled so that high notes remain clean.

The model has five parts:

• A non-linear reed, copied from STK.

• A pitched vortex noise generator, as patented by Dr. Chris Chafe.

• A bore with register holes that properly play in the chalumeau, clarino, and altissimo registers.

• A conical bell made of a 40-stage Kelly-Lochbaum ladder filter.

• A two-dimensional dynamic equalizer for making final timbre adjustments.

The model has nine adjustable parameters:

• Register – The state of the register holes.
• Stiffness – The stiffness of the reed.
• Aperture – The distance between the reed and the mouthpiece.
• Noise – The amount of vortex breath noise.
• Absorption – The tone of the reflection received from the bell.
• Damping – The amount of reflection received from the bell.
• Finger Time – The time to open and close tone holes while playing.
• Timbre – Minor timbre adjustment, for some variety.
• Half-Finger – The distance that tone holes are raised or lowered.

Vibrato and flutter tonguing are included.

I also added six optional trumpet mutes that can be placed onto the bell. No, they make no sense on a clarinet. But I had the filter specifications for them, so why not?

A single MIDI modulation bus is included, with 10 sources and 15 destinations, but most of it is unfinished.

I've now finished it. It now includes three different clarinets. Also attached is a short tune played with it.
