<h2>Performance</h2>
<p>
<span class="emphasis"><em>k1 ... k64</em></span> -- output values
</p>
<p>
<span class="emphasis"><em>slider64f</em></span> is a bank of MIDI controllers, useful when using MIDI mixer such as Kawai MM-16 or others for changing whatever sound parameter in real-time. The raw MIDI control messages at the input port are converted to agree with <span class="emphasis"><em>iminN</em></span> and <span class="emphasis"><em>imaxN</em></span>, and an initial value can be set. Also, an optional non-interpolated function table with a custom translation curve is allowed, useful for enabling exponential response curves.
</p>
<p>
When no function table translation is required, set the <span class="emphasis"><em>ifnN</em></span> value to 0, else set <span class="emphasis"><em>ifnN</em></span> to a valid function table number. When table translation is enabled (i.e. setting <span class="emphasis"><em>ifnN</em></span> value to a non-zero number referring to an already allocated function table), <span class="emphasis"><em>initN</em></span> value should be set equal to <span class="emphasis"><em>iminN</em></span> or <span class="emphasis"><em>imaxN</em></span> value, else the initial output value will not be the same as specified in <span class="emphasis"><em>initN</em></span> argument.
</p>
<p>
<span class="emphasis"><em>slider64f</em></span> allows a bank of 64 different MIDI control message numbers. It filters the signal before output. This eliminates discontinuities due to the low resolution of the MIDI (7 bit). The cutoff frequency can be set separately for each controller (suggested range: .1 to 5 Hz).
</p>
<p>
As the input and output arguments are many, you can split the line using '\' (backslash) character (new in 3.47 version) to improve the readability. Using these opcodes is considerably more efficient than using the separate ones (<a class="link" href="ctrl7.html" title="ctrl7"><em class="citetitle">ctrl7</em></a> and <a class="link" href="tonek.html" title="tonek"><em class="citetitle">tonek</em></a>) when more controllers are required.
