139 <p>
140 These are the built-in variables and built-in constants available with the
141 NKSP realt-time instrument script language.

143
144 <h3>Common Sampler Variables</h3>
145 <p>
146 Basic sampler related built-in variables and constants, independent from a
147 particular sampler format or sampler engine.

149 <table>
150 <tr>
151 <th>Variable</th> <th>Description</th>
152 </tr>
153 <tr>
154 <td><code>$CC_NUM</code></td>

156 handler to be executed (only useful in the context of a
157 <code>controller</code> handler).</td>
158 </tr>

161 <td>Provides access to all current MIDI controller values. This can be
162 used in any context. Use the respective MIDI controller number as
163 index to this integer array variable. For instance <code>%CC[1]</code>
164 would give you the current value of the modulation wheel.
165 </td>
166 </tr>
167 <tr>
168 <td><code>$EVENT_ID</code></td>
169 <td>ID of the event that caused the current event handler to be executed. In
170 the context of a <code>note</code> handler this would be the event
171 ID of the note, within a <code>controller</code> handler it would
172 be the controller event ID, etc.</td>
173 </tr>
174 <tr>
175 <td><code>$EVENT_NOTE</code></td>
176 <td>MIDI note number that caused a note related
177 handler to be executed (only useful in the context of a
178 <code>note</code> or <code>release</code> handler).</td>

183 handler to be executed (only useful in the context of a
184 <code>note</code> or <code>release</code> handler).</td>
185 </tr>
186 <tr>
187 <td><code>%KEY_DOWN[]</code></td>
188 <td>This can be used in any context to check whether a certain MIDI
189 key is currently pressed down. Use the respective MIDI note number
190 as index to this array variable (see also <code>event_status()</code>).</td>

195 called <i title="Amount of force on held-down key.">
196 MIDI channel pressure
197 </i>). This is somewhat different than in the MIDI standard. With
198 NKSP aftertouch is handled like an additional "regular" MIDI CC controller.
199 Therefore use
200 <code>%CC[$VCC_MONO_AT]</code> to obtain the current aftertouch value
201 in the context of a <code>controller</code> event handler.
202 </td>

206 <td>Constant identifying the pitch bend wheel controller.
207 This is somewhat different than in the MIDI standard. With
208 NKSP pitch bend is handled like an additional "regular" MIDI CC controller.
209 Therefore use
210 <code>%CC[$VCC_PITCH_BEND]</code> to obtain the current pitch bend wheel value
211 in the context of a <code>controller</code> event handler.</td>
