## STKClarinet

STKClarinet — STKClarinet uses a simple clarinet physical model.

## Description

Plugin opcode in stkopd.

STKClarinet uses a simple clarinet physical model.

## Syntax

    asignal STKClarinet ifrequency, iamplitude, [kstiff, kv1[, knoise, kv2[, klfo, kv3[, klfodepth, kv4[, kbreath, kv5]]]]]

## Initialization

ifrequency -- Frequency of note played, in Hertz.

iamplitude -- Amplitude of note played (range 0-1).

## Performance

kstiff -- controller 2, reed stiffness. Value range of kv1 is 0-127.

knoise -- controller 4, gain of noise. Value range of kv2 is 0-127.

klfo -- controller 11, speed of low-frequency oscillator. Value range of kv3 is 0-127.

klfodepth -- controller 1, depth of low-frequency oscillator. Value range of kv4 is 0-127.

kbreath -- controller 128, breath pressure. Value range of kv5 is 0-127.

| Note

The code for this opcode is taken directly from the Clarinet class in the Synthesis Toolkit in C++ by Perry R. Cook and Gary P. Scavone. More on the STK classes can be found here: https://ccrma.stanford.edu/software/stk/classes.html

kc1, kv1, kc2, kv2, kc3, kv3, kc4, kv4, kc5, kv5, kc6, kv6, kc7, kv7, kc8, kv8 -- Up to 8 optional k-rate controller pairs for the STK opcodes. Each controller pair consists of a controller number (kc) followed by a controller value (kv). Both the controller numbers and the controller values are krate variables. However, during a performance, normally the controller numbers stay fixed while the corresponding controller values may change at any time. The order of the controller pair is arbitrary, as long as they are after iamplitude. Also, it is not needed that all controller pairs are used.

## Examples

Here is an example of the STKClarinet opcode. It uses the file STKClarinet.csd.
