## Description

GigaSampler region objects are children of IpatchGigInst objects.

## Details

### IpatchGigRegion

    typedef struct _IpatchGigRegion IpatchGigRegion;

### enum IpatchGigRegionFlags

    typedef enum
    {
      IPATCH_GIG_REGION_SELF_NON_EXCLUSIVE = 1 << IPATCH_CONTAINER_UNUSED_FLAG_SHIFT,
      IPATCH_GIG_REGION_PHASE_MASTER = 1 << (IPATCH_CONTAINER_UNUSED_FLAG_SHIFT + 1),
      IPATCH_GIG_REGION_MULTI_CHANNEL = 1 << (IPATCH_CONTAINER_UNUSED_FLAG_SHIFT + 2)
    } IpatchGigRegionFlags;

### IPATCH_GIG_REGION_FLAG_MASK

    #define IPATCH_GIG_REGION_FLAG_MASK  (0x0F << IPATCH_CONTAINER_UNUSED_FLAG_SHIFT)

### IPATCH_GIG_REGION_UNUSED_FLAG_SHIFT

    #define             IPATCH_GIG_REGION_UNUSED_FLAG_SHIFT

### ipatch_gig_region_new ()

    IpatchGigRegion *   ipatch_gig_region_new               (void);

Create a new GigaSampler instrument region.

Returns : | New GigaSampler region with a ref count of 1 which the caller owns.

### ipatch_gig_region_first ()

    IpatchGigRegion *   ipatch_gig_region_first             (IpatchIter *iter);

Gets the first item in a region iterator. A convenience wrapper for `ipatch_iter_first()`.

`iter` : | Patch item iterator containing IpatchGigRegion items
Returns : | The first region in `iter` or `NULL` if empty.

### ipatch_gig_region_next ()

    IpatchGigRegion *   ipatch_gig_region_next              (IpatchIter *iter);

Gets the next item in a region iterator. A convenience wrapper for `ipatch_iter_next()`.

`iter` : | Patch item iterator containing IpatchGigRegion items
Returns : | The next region in `iter` or `NULL` if at the end of the list.

### ipatch_gig_region_set_note_range ()

    void                ipatch_gig_region_set_note_range    (IpatchGigRegion *region,
                                                             int low,
                                                             int high);

Set the MIDI note range that a region is active on.

`region` : | Region to set note range of
`low` : | Low value of range (MIDI note # between 0 and 127)
`high` : | High value of range (MIDI note # between 0 and 127)

### ipatch_gig_region_set_velocity_range ()

    void                ipatch_gig_region_set_velocity_range
                                                            (IpatchGigRegion *region,
                                                             int low,
                                                             int high);

Set the MIDI velocity range that a region is active on.

`region` : | Region to set velocity range of
`low` : | Low value of range (MIDI velocity # between 0 and 127)
`high` : | High value of range (MIDI velocity # between 0 and 127)

### ipatch_gig_region_new_dimension ()

    void                ipatch_gig_region_new_dimension     (IpatchGigRegion *region,
                                                             IpatchGigDimensionType type,

Adds a new dimension to a GigaSampler region. The dimension is allocated `split_count` number of dimension bits which means the total number of sub regions will be multiplied by a factor of 2 to the power of `split_count`. There can be a maximum of 32 sub regions for a total of 5 used split bits.

`region` : | GigaSampler region
`type` : | Type of dimension to add
`split_count` : | Split bit count

### ipatch_gig_region_remove_dimension ()

    void                ipatch_gig_region_remove_dimension  (IpatchGigRegion *region,

Removes a dimension from a GigaSampler region, including all related sub regions (except those that correspond to the `split_index`), and re-organizes sub regions for new dimension map.

`region` : | GigaSampler region
`dim_index` : | Index of an existing dimension to remove (0-4)
`split_index` : | Split index to use in the dimension to remove
