It works only with MIDI instruments which recognize them. It can drive a different value of a parameter for each note currently active. </p> <p> It can scale the k-value floating-point argument according to the <span class="emphasis"><em>kmin</em></span> and <span class="emphasis"><em>kmax</em></span> values. For example: set <span class="emphasis"><em>kmin</em></span> = 1.0 and <span class="emphasis"><em>kmax</em></span> = 2.0. When the <span class="emphasis"><em>kvalue</em></span> argument receives a 2.0 value, the opcode will send a 127 value to the MIDI OUT device. When the <span class="emphasis"><em>kvalue</em></span> argument receives a 1.0 value, it will send a 0 value. k-rate opcodes send a message each time the MIDI converted value of argument <span class="emphasis"><em>kvalue</em></span> changes. </p> </div> <div class="refsect1"> <a id="idm281472907352776"></a> <h2>Examples</h2> <p> Here is an example of the outkc opcode.
