VST Events
struct VstEvent;
A generic timestamped event.
long type; |
Any of the following constants :
kVstMidiType |
midi event, can be cast as VstMidiEvent |
kVstAudioType |
audio |
kVstVideoType |
video |
kVstParameterType |
parameter |
kVstTriggerType |
trigger |
|
long byteSize; |
of this event, excl. type and byteSize |
long deltaFrames; |
sample frames related to the current block start sample position |
long flags; |
generic flags, none defined yet (0) |
char data[16]; |
size may vary but is usually 16 |
struct VstMidiEvent;
To be casted from a VstEvent
.
long type; |
kVstMidiType |
long byteSize; |
24 |
long deltaFrames; |
sample frames related to the current block start sample position |
long flags; |
none defined yet |
long noteLength; |
(in sample frames) of entire note, if available, else 0 |
long noteOffset; |
offset into note from note start if available, else 0 |
char midiData[4]; |
1 thru 3 midi bytes; midiData[3] is reserved (zero) |
char detune; |
-64 to +63 cents; for scales other than 'well-tempered' ('microtuning') |
char noteOffVelocity; |
|
char reserved1; |
zero |
char reserved2;
|
zero |
struct VstEvents;
A block of events for the current audio block.
long numEvents; |
|
long reserved; |
zero |
VstEvent* events[2]; |
variable |
virtual void wantEvents (long filter = 1);
Asks the host to send VstEvents
, as would request an instrument.
This call can't be issued at construction time, it should be done in the
resume
method instead.
filter |
Currently ignored, midi channel data only (default). |

bool sendVstEventsToHost (VstEvents* events);
See discussion of VstEvents
, and Steinberg products implementation
issues.
events |
A pointer to a VstEvents structure. |
|
return |
true : |
Success. |
false : |
Failure. |
|
virtual long processEvents (VstEvents* events);
Override this to evaluate VstEvents
that may be sent to your plug
due to a wantEvents
request.
