chani — Reads data from the software bus

## Description

Reads data from a channel of the inward software bus.

## Syntax

    kval chani kchan

    aval chani kchan

## Performance

kchan -- a positive integer that indicates which channel of the software bus to read

Note that the inward and outward software busses are independent, and are not mixer buses. Also the k-rate and a-rate busses are independent. The last value remains until a new value is written. There is no imposed limit to the number of busses but they use memory so small numbers are to be preferred.

## Example

The example shows the software bus being used as an asynchronous control signal to select a filter cutoff. It assumes that an external program that has access to the API is feeding the values

            sr = 44100
            kr = 100
            ksmps = 1

            instr   1
               kc   chani     1
               a1   oscil     p4, p5, 100
               a2   lowpass2  a1, kc, 200
                    out       a2
            endin
