STKSitar

STKSitar — STKSitar uses a plucked string physical model.

Description

STKSitar uses a plucked string physical model based on the Karplus-Strong algorithm.

Syntax

asignal STKSitar ifrequency, iamplitude

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). There are no controller numbers and values that work for STKSitar.

[Note] Note

The code for this opcode is taken directly from the Sitar 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

Examples

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