This request returns a Cue Stack Info data structure for the specified preset zone. Use this response to determine which presets are active in a given zone.




  • name=<zoneName>
    • The name of the desired zone.


The following variable-length structure is returned by this request:

#define STACK_NAME_BUF_SIZE     16
#define CSI_TYPE_CUES           0
#define CSI_TYPE_PRESETS        1

typedef struct CueStackInfo {
    uint16_t            signature;              // Signature = 'CS'
    int16_t             version;                // Version = 0x0001 (or negative error code)
    char                stackName[STACK_NAME_BUF_SIZE]; // Name of stack
    uint8_t             type;                   // 0 = Cues, 1 = Presets
    uint8_t             playback;               // The playback number (for presets only)
    uint16_t            count;                  // Number of CueID/Status pairs
    uint32_t            data[64];               // Array of CueID/Status pairs (32 pairs max)
} CueStackInfo;

The CueID/Status pairs are included for any preset in the zone that is active. The CueID denotes the preset number and the Status value indicates the preset’s active state. The following table shows preset states:

Preset Status Description
1 This preset is active.
2 This preset is modified.
