|
This function can be used to change the sample playback position of the |
11 |
|
|
voices of the requested note. You need to pass the note ID of the voices |
12 |
|
|
you want to alter. This function will change the sample playback position |
13 |
|
|
of all voices associated with the requested note. |
14 |
|
|
</p> |
15 |
|
|
<p> |
16 |
|
|
At the moment you may only use this function for new notes. |
17 |
|
|
That effectively means you should change the sample playback position with |
18 |
|
|
this function before any <code lang="nksp">wait()</code> calls, and before |
19 |
|
|
entering any loops that may execute your script for a very long time. |
20 |
|
|
Using this function for notes which alreay play for a while does not raise an error, |
21 |
|
|
but calling this function will simply be ignored for such older notes, and |
22 |
|
|
thus will have no effect. This current limitation might change in future. |

|
<note class="important"> |
26 |
|
|
In case the respective sample is using disk streaming, then you might be |
27 |
|
|
limited to set the new playback position somwehere within a certain |
28 |
|
|
range at the beginning of the sample (i.e. less than several hundred |
29 |
|
|
milliseconds from sample start). The precise range depends on the |
30 |
|
|
sampler configuration and the sampler format engine being used. |
31 |
|
|
Setting a position beyond that maximum position might either cause your |
32 |
|
|
position to be automatically corrected by the sampler, or that the resulting |
33 |
|
|
voices will not play at all. |
