Silverwood Bb Clarinets
Experimental breath-controlled clarinet physical model
DESCRIPTION
Silverwood Bb Clarinets is an experimental synthesizer that mimics a Bb clarinet. It creates sounds using waveguide physical modeling synthesis. It’s an attempt to revisit and try to improve the original clarinet model in Silverwood.
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). I'm currently using a TEC breath controller, available at http://www.tecontrol.se/products/usb-midi-breath-controller. It plugs right into my computer's USB port. It's very nice.
The sample rate must be 44.1 or 48.0 kHz. Internally, the model is 4x oversampled.
The original Silverwood clarinet model was simply a nonlinear reed connected to a delay line, followed by a graphic equalizer. This updated model has five parts:
• The same nonlinear reed used in Silverwood.
• 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 eight adjustable parameters:
• Register – The state of the two 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.
• Half-Finger – The distance that tone holes are raised.
Three clarinet models are supplied, each with slightly different timbres. Also, five different mutes can be placed onto the bell.
Vibrato and flutter tonguing are included.
Six MIDI modulation busses are included, with 10 sources and 15 destinations. Each snap responds in some way to pitchbend changes, both up and down.
The sample mp3 demonstrates the Basic snap.
