STKModalBar

STKModalBar — STKModalBar is a resonant bar instrument.

Description

This opcode is a resonant bar instrument.It has a number of different struck bar instruments.

Syntax

asignal STKModalBar ifrequency, iamplitude, [kc1, kv1[, kc2, kv2[, kc3, kv3[, kc4, kv4[, kc5, kv5[, kc6, kv6[, kc7, kv7]]]]]]]

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 7 controller numbers and values that work for STKModalBar are:

  • kc, kv -- 2, hardness of the stick.

  • kc, kv -- 4, stick position.

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

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

  • kc, kv -- 8, direct stick mix.

  • kc, kv -- 128, volume.

  • kc, kv -- 16, instrument presets (0 = marimba, 1 = vibraphone, 2 = agogo, 3 = wood1, 4 = reso, 5 = wood2, 6 = beats, 7 = two fixed, 8 = clump).

[Note] Note

The code for this opcode is taken directly from the ModalBar 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
