STKClarinet

STKClarinet — STKClarinet uses a simple clarinet physical model.

Description

STKClarinet uses a simple clarinet physical model.

Syntax

asignal STKClarinet ifrequency, iamplitude, [kc1, kv1[, kc2, kv2[, kc3, kv3[, kc4, kv4[, kc5, kv5]]]]]

Initialization

ifrequency -- Frequency of note played, in Hertz.

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

Performance

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). The 5 controller numbers and values that work for STKClarinet are:

  • kc, kv -- 2, reed stiffness.

  • kc, kv -- 4, gain of noise.

  • kc, kv -- 11, speed of low-frequency oscillator.

  • kc, kv -- 1, depth of low-frequency oscillator.

  • kc, kv -- 128, breath pressure.

[Note] 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
