These are the built-in variables and built-in constants available with the NKSP realt-time instrument script language.
Most fundamental NKSP built-in variables, independent from any purpose of being used in a sampler.
Variable | Description |
---|---|
$KSP_TIMER |
Preserved for compatiblity reasons with KSP, returns the same value
as $NKSP_REAL_TIMER (refer to the latter for details).
Note that KSP's reset_ksp_timer() function is not available with
NKSP. However when calculating time differences between two time
stamps taken with $NKSP_REAL_TIMER , calling such a reset
function is not required, because the underlying clock does not stop
when it reached its value limit (which happens every 71 minutes), instead the clock
will automatically restart from zero and the calculated time difference
even between such transitions will reflect correct durations. |
$NKSP_PERF_TIMER |
Returns the current performance time stamp (in microseconds) of the
script running. You may read this variable from time to time to take
time stamps which can be used to calculate the time difference
(in microseconds) which elapsed between them. A performance time
stamp is based on the script's actual CPU execution time. So the
internal clock which is used for generating such time stamps is only
running forward if the respective script is actually executed by the
CPU. Whenever your script is not really executed by the CPU (i.e. because
your script got suspended by a wait() call or got forcely suspended due to
real-time constraints, or when the entire sampler application got suspended
by the OS for other applications or OS tasks) then the underlying internal
clock is paused as well.
$ENGINE_UPTIME instead, which is
also safe for offline bounces.
$NKSP_REAL_TIMER and
$NKSP_PERF_TIMER will actually return the same value. So the
difference between them is not implemented for all systems at the moment.
|
$NKSP_REAL_TIMER |
Returns the current time stamp in reality (in microseconds). You may
read this variable from time to time to take
time stamps which can be used to calculate the time difference
(in microseconds) which elapsed between them. A "real" time
stamp is based on an internal clock which constantly proceeds, so this
internal clock also continues counting while your script is either suspended
(i.e. because your script got suspended by a wait() call or got forcely
suspended due to real-time constraints) and it also continues counting
even if the entire sampler application got suspended by the OS (i.e. to
execute other applications for multi-tasking or to perform OS tasks).
$ENGINE_UPTIME instead, which is
also safe for offline bounces.
$NKSP_REAL_TIMER and
$NKSP_PERF_TIMER will actually return the same value. So the
difference between them is not implemented for all systems at the moment.
|
$NI_CALLBACK_ID |
Reflects the current event handler instance's unique callback ID. For the same event type there may be more than one event handler instances running. Each one of them has its own callback ID. You can get the current event handler instance's callback ID by reading this built-in variable. |
$NI_CALLBACK_TYPE |
Reflects the event type of the current event handler. This variable
may reflect one of the following built-in constants:
$NI_CB_TYPE_INIT , $NI_CB_TYPE_NOTE ,
$NI_CB_TYPE_RELEASE , $NI_CB_TYPE_CONTROLLER . |
$NI_CB_TYPE_INIT |
Built-in constant reflecting an init event handler type. |
$NI_CB_TYPE_NOTE |
Built-in constant reflecting a note event handler type. |
$NI_CB_TYPE_RELEASE |
Built-in constant reflecting a release event handler type. |
$NI_CB_TYPE_CONTROLLER |
Built-in constant reflecting a controller event handler type. |
$NKSP_IGNORE_WAIT |
If this boolean built-in variable is 1 then all calls of your
event handler instance to function wait() will be ignored.
This may for example be the case if another event handler instance
resumed your paused script by calling stop_wait() and
passing 1 to the 2nd argument of that function. |
Basic sampler related built-in variables and constants, independent from a particular sampler format or sampler engine.
Variable | Description |
---|---|
%ALL_EVENTS |
Note IDs of all currently active notes of the current sampler part (a.k.a. sampler channel).
This may be passed to many built-in functions like note_off() .
This array variable only contains IDs of notes which were launched due
to MIDI note-on events. This variable does not contain IDs of child notes
(i.e. notes which were launched programmatically by calling play_note() ).
$ALL_EVENTS . Using the latter with NKSP will cause a
parser warning, the behavior will be the same though.
|
$CC_NUM |
MIDI controller number that caused the controller
handler to be executed (only useful in the context of a
controller handler). |
%CC[] |
Provides access to all current MIDI controller values. This can be
used in any context. Use the respective MIDI controller number as
index to this integer array variable. For instance %CC[1]
would give you the current value of the modulation wheel.
|
$EVENT_ID |
ID of the event that caused the current event handler to be executed. In
the context of a note handler this would be the event
ID of the note, within a controller handler it would
be the controller event ID, etc. |
$EVENT_NOTE |
MIDI note number that caused a note related
handler to be executed (only useful in the context of a
note or release handler). |
$EVENT_VELOCITY |
MIDI velocity value of the note that caused that note related
handler to be executed (only useful in the context of a
note or release handler). |
$EVENT_STATUS_INACTIVE |
Constant bit flag used as possible return value by
event_status() in case the requested
note is not "alive". |
$EVENT_STATUS_NOTE_QUEUE |
Constant bit flag used as possible return value by
event_status() in case the requested
note is still "alive". |
$EVENT_PAR_NOTE |
Constant value symbolizing the "note number" parameter. See
get_event_par() and set_event_par()
for details. |
$EVENT_PAR_TUNE |
Constant value symbolizing the "tune" parameter. See
get_event_par() and set_event_par()
for details. |
$EVENT_PAR_VELOCITY |
Constant value symbolizing the "note velocity" parameter. See
get_event_par() and set_event_par()
for details. |
$EVENT_PAR_VOLUME |
Constant value symbolizing the "volume" parameter. See
get_event_par() and set_event_par()
for details. |
$EVENT_PAR_0 to $EVENT_PAR_3 |
Four constant values symbolizing the 4 possible user specific
parameters, which i.e. might be used to pass data from one script
(slot) to another script (slot). See get_event_par()
and set_event_par() for details. |
%KEY_DOWN[] |
This can be used in any context to check whether a certain MIDI
key is currently pressed down. Use the respective MIDI note number
as index to this array variable (see also event_status() ). |
$NKSP_EASE_IN_EASE_OUT |
Used to select a fade curve with "ease in and ease out" shape. |
$NKSP_LINEAR |
Used to select a fade curve with linear shape. |
$VCC_MONO_AT |
Constant identifying the MIDI monophonic aftertouch controller (also
called
MIDI channel pressure
). This is somewhat different than in the MIDI standard. With
NKSP aftertouch is handled like an additional "regular" MIDI CC controller.
Therefore use
%CC[$VCC_MONO_AT] to obtain the current aftertouch value
in the context of a controller event handler.
|
$VCC_PITCH_BEND |
Constant identifying the pitch bend wheel controller.
This is somewhat different than in the MIDI standard. With
NKSP pitch bend is handled like an additional "regular" MIDI CC controller.
Therefore use
%CC[$VCC_PITCH_BEND] to obtain the current pitch bend wheel value
in the context of a controller event handler. |
$MARK_1 to $MARK_28 |
Used to select one of the available 28 event groups.
See set_event_mark() for details. |
$ENGINE_UPTIME |
Returns the current time stamp (in milliseconds) for being used in a musical context. You may read this variable from time to time to take time stamps which can be used to calculate the time difference (in milliseconds) which elapsed between them. These timing values are based on the internal sample rate and thus it can safely be used to perform musical timing related tasks in your scripts. Especially your script will also continue to behave correctly when an offline bounce of a song is performed. |
