# ampmidi

ampmidi -- Get the velocity of the current MIDI event.

## Description

Get the velocity of the current MIDI event.

## Syntax

iamp ampmidi iscal [, ifn]

## Initialization

iscal -- i-time scaling factor

ifn (optional, default=0) -- function table number of a normalized translation table, by which the incoming value is first interpreted. The default value is 0, denoting no translation.

## Performance

Get the velocity of the current MIDI event, optionally pass it through a normalized translation table, and return an amplitude value in the range 0 - iscal.

## Examples

Here is an example of the ampmidi opcode. It uses the files ampmidi.orc and ampmidi.sco.

Example 1. Example of the ampmidi opcode.

    /* ampmidi.orc */
    ; Initialize the global variables.
    sr = 44100
    kr = 4410
    ksmps = 10
    nchnls = 1

    ; Instrument #1.
    instr 1
      ; Scale the amplitude between 0 and 1.
      i1 ampmidi 1

      print i1
    endin
    /* ampmidi.orc */

    /* ampmidi.sco */
    ; Play Instrument #1 for 12 seconds.
    i 1 0 12
    e
    /* ampmidi.sco */
