The larger its value, the longer it takes for the sound to be reflected and return. The units are in milliseconds and must be set in multiples of 5, at a value of 5 or larger. The initial value is set to 60.</p><p><CODE>m_EarlyGain</CODE> represents the initial reflection's output gain. Configure a value between 0.0f and 1.0f. When you set it to 0.0f, you will no longer hear the initial reflection. The initial value is set to 0.6f.</p><p>The back-end reverberation can be adjusted with <CODE>m_FusedTime</CODE>, <CODE>m_FusedGain</CODE>, <CODE>m_PreDelayTime</CODE>, <CODE>m_Coloration</CODE>, <CODE>m_Damping</CODE> and <CODE>m_pFilterSize</CODE>.</p><p><CODE>m_FusedTime</CODE> represents how long the back-end reverberation will continue to sound. The larger this value is, the easier it is to express the space as one in which echoes occur. The units are in milliseconds and the initial value is set to 4,000.</p><p><CODE>m_FusedGain</CODE> represents the back-end reverberation's output gain. Configure a value between <CODE>0.0f</CODE> and <CODE>1.0f</CODE>. When you set it to 0.0f, you will no longer hear the back-end reverberation. The initial value is set to 0.4f.</p><p><CODE>m_PreDelayTime</CODE> represents the delay time placed before the back-end reverberation. The larger this value is, the greater the delay before we hear the back-end reverberation. The units are in milliseconds and must be set in multiples of 5, at a value of 5 or larger. The initial value is 100.</p><p><CODE>m_Coloration</CODE> represents the coefficient for the back-end reverberation's all-pass filter. The larger this value, the more detailed the back-end reverberation, and the more complex the reverberation will become. Configure a value between <CODE>0.0f</CODE> and <CODE>1.0f</CODE>. When set to 0.0f the all-pass filter will be completely open. This value is initially 0.5f.</p><p><CODE>m_Damping</CODE> represents the behavior of the low-pass filter (LPF) on the back-end reverberation. Configure a value between <CODE>0.0f</CODE> and <CODE>1.0f</CODE>. Increasing this value decreases the cutoff frequency. If you specify a value of 0.0f, the LPF is not applied. This value is initially 0.4f.</p><p>See the description of <CODE><A>FilterSize</A></CODE> for more on the member variables of <CODE>m_pFilterSize</CODE>.</p><p>The necessary memory that you can get with the <CODE><a href="../../../../../nn/snd/CTR/FxReverb/GetRequiredMemSize.html">GetRequiredMemSize</a></CODE> function is dependent on <CODE>m_EarlyReflectionTime</CODE>, <CODE>m_PreDelayTime</CODE> and <CODE>m_pFilterSize</CODE>.</p><p>Changing the following values while an effect is executing can cause noise. ・<CODE>m_EarlyReflectionTime</CODE> <br /> ・<CODE>m_PreDelayTime</CODE></p><p>Continually changing the following values even while an effect is executing can cause noise. ・<CODE>m_FusedTime</CODE> <br /> ・<CODE>m_Coloration</CODE> <br /> ・<CODE>m_Damping</CODE> <br /> ・<CODE>m_EarlyGain</CODE> <br /> ・<CODE>m_FusedGain</CODE></p><p>To change a parameter while an effect is executing, call the <CODE><a href="../../../../../nn/snd/CTR/FxDelay/SetParam.html">SetParam</a></CODE> function.</p><!-- write here --></div> 72 <a name="variable" id="variable"> 73<h2>Member Variables</h2> 74 <div class="section"> 75 <table class="members"> 76 <tr> 77 <td width="100"> </td> 78 <th> 79<span class="argument">m_EarlyReflectionTime</span> 80 </th> 81<td>The initial reflection time (in msec).</td> 82 </tr> 83 <tr> 84 <td width="100"> </td> 85 <th> 86<span class="argument">m_FusedTime</span> 87 </th> 88<td>The attenuation time (in msec) of the back-end reverberation.</td> 89 </tr> 90 <tr> 91 <td width="100"> </td> 92 <th> 93<span class="argument">m_PreDelayTime</span> 94 </th> 95<td>The pre-delay time (in msec) of the back-end reverberation.</td> 96 </tr> 97 <tr> 98 <td width="100"> </td> 99 <th> 100<span class="argument">m_Coloration</span> 101 </th> 102<td>The coefficient of the all-pass filter for the back-end reverberation.</td> 103 </tr> 104 <tr> 105 <td width="100"> </td> 106 <th> 107<span class="argument"><CODE>m_Damping</CODE></span> 108 </th> 109<td>The behavior of the LPF for the back-end reverberation.</td> 110 </tr> 111 <tr> 112 <td width="100"> </td> 113 <th> 114<span class="argument">m_pFilterSize</span> 115 </th> 116<td>The filter size.
