Detailed Description

Defines Region information of an Instrument.

Definition at line 493 of file DLS.h.

Constructor & Destructor Documentation

◆ ~Region()

DLS::Region::~Region ( )
protectedvirtual

Destructor.

Intended to free up all memory occupied by this Region object. ATM this destructor implementation does nothing though.

Reimplemented in gig::Region.

Definition at line 1177 of file DLS.cpp.

Member Function Documentation

◆ AddSampleLoop()

void DLS::Sampler::AddSampleLoop ( sample_loop_t pLoopDef)
inherited

Adds a new sample loop with the provided loop definition.

Parameters
pLoopDef- points to a loop definition that is to be copied

Definition at line 742 of file DLS.cpp.

References DLS::sample_loop_t::Size.

◆ CopyAssign() [1/3]

void Resource::CopyAssign ( const Resource orig)
virtualinherited

Make a deep copy of the Resource object given by orig and assign it to this object.

Parameters
orig- original Resource object to be copied from

Definition at line 637 of file DLS.cpp.

Referenced by CopyAssign(), DLS::Sample::CopyAssignCore(), and DLS::Instrument::DeleteChunks().

◆ CopyAssign() [2/3]

void DLS::Sampler::CopyAssign ( const Sampler orig)
virtualinherited

Make a deep copy of the Sampler object given by orig and assign it to this object.

Parameters
orig- original Sampler object to be copied from

Definition at line 788 of file DLS.cpp.

References DLS::Sampler::Gain, DLS::Sampler::pSampleLoops, and DLS::Sampler::SampleLoops.

Referenced by CopyAssign().

◆ CopyAssign() [3/3]

void DLS::Region::CopyAssign ( const Region orig)
virtual

Make a (semi) deep copy of the Region object given by orig and assign it to this object.

Note that the sample pointer referenced by orig is simply copied as memory address. Thus the respective sample is shared, not duplicated!

Parameters
orig- original Region object to be copied from

◆ DeleteChunks()

void DLS::Region::DeleteChunks ( )
virtual

◆ DeleteSampleLoop()

void DLS::Sampler::DeleteSampleLoop ( sample_loop_t pLoopDef)
inherited

Deletes an existing sample loop.

Parameters
pLoopDef- pointer to existing loop definition
Exceptions
Exception- if given loop definition does not exist

Definition at line 764 of file DLS.cpp.

◆ GetArticulation()

Articulation * DLS::Articulator::GetArticulation ( size_t  pos)
inherited

Returns Articulation at supplied pos position within the articulation list.

If supplied pos is out of bounds then NULL is returned.

Parameters
pos- position of sought Articulation in articulation list
Returns
pointer address to requested articulation or NULL if pos is out of bounds

Definition at line 200 of file DLS.cpp.

◆ GetFirstArticulation()

Articulation * DLS::Articulator::GetFirstArticulation ( )
inherited

Returns the first Articulation in the list of articulations.

You have to call this method once before you can use GetNextArticulation().

Returns
pointer address to first Articulation or NULL if there is none
See also
GetNextArticulation()
Deprecated:
This method is not reentrant-safe, use GetArticulation() instead.

Definition at line 216 of file DLS.cpp.

◆ GetNextArticulation()

Articulation * DLS::Articulator::GetNextArticulation ( )
inherited

Returns the next Articulation from the list of articulations.

You have to call GetFirstArticulation() once before you can use this method. By calling this method multiple times it iterates through the available articulations.

Returns
pointer address to the next Articulation or NULL if end reached
See also
GetFirstArticulation()
Deprecated:
This method is not reentrant-safe, use GetArticulation() instead.

◆ SetKeyRange()

void DLS::Region::SetKeyRange ( uint16_t  Low,
uint16_t  High 
)
virtual

Modifies the key range of this Region and makes sure the respective chunks are in correct order.

Parameters
Low- lower end of key range
High- upper end of key range

Reimplemented in gig::Region.

Definition at line 1228 of file DLS.cpp.

Referenced by gig::Region::SetKeyRange().

◆ SetSample()

void DLS::Region::SetSample ( Sample pSample)

Assign another sample to this Region.

Parameters
pSample- sample to be assigned

Definition at line 1216 of file DLS.cpp.

◆ UpdateChunks()

void DLS::Region::UpdateChunks ( progress_t pProgress)
virtual

Apply Region settings to the respective RIFF chunks.

You have to call File::Save() to make changes persistent.

Parameters
pProgress- callback function for progress notification
Exceptions
Exception- if the Region's sample could not be found

Reimplemented from DLS::Articulator.

Reimplemented in gig::Region.
