## scantable

scantable — A simpler scanned synthesis implementation.

## Description

A simpler scanned synthesis implementation. This is an implementation of a circular string scanned using external tables. This opcode will allow direct modification and reading of values with the table opcodes.

## Syntax

    aout scantable kamp, kpch, ipos, imass, istiff, idamp, ivel

## Initialization

ipos -- table containing position array.

imass -- table containing the mass of the string.

istiff -- table containing the stiffness of the string.

idamp -- table containing the damping factors of the string.

ivel -- table containing the velocities.

## Performance

kamp -- amplitude (gain) of the string.

kpch -- the string's scanned frequency.

## Examples

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