    <title>Performance</title>
    <para>
      <emphasis>outiat</emphasis> (i-rate aftertouch output) sends aftertouch messages. It works only with MIDI instruments which recognize them. It can drive a different value of a parameter for each note currently active. 
    </para>

    <para>
      It can scale an i-value floating-point argument according to the <emphasis>imin</emphasis> and <emphasis>imax</emphasis> values. For example, set <emphasis>imin</emphasis> = 1.0 and <emphasis>imax</emphasis> = 2.0. When the <emphasis>ivalue</emphasis> argument receives a 2.0 value, the opcode will send a 127 value to the MIDI OUT device. When the <emphasis>ivalue</emphasis> argument receives a 1.0 value, it will send a 0 value. i-rate opcodes send their message once during instrument initialization.
