Due to the type of memory technology and the implementation of the memory 
interface, every physical address jump within the sample memory will reduce the 
bandwidth at the memory interface. The drawing below shows such an address jump.   
To put the density of address jumps below a limit, a minimum segment length of 257 
sample vectors (big segment) is required. Small segments (256 vectors down to 5 
vectors) are also possible but then the linear playtime requirement must be met. 
 
Linear Playtime Requirement: 
  The playtime of at least 257 sample vectors (257 sync clock cycles) must be placed 
in the sample memory in an ascending address order. When writing samples to a 
totally cleared memory, the order of segments is the order of how these segments 
are written to the memory.  
  Idle delay segments are also considered in computing the playtime. The 
corresponding playtime in  sample vectors is computed from the idle delay value. 
When the data segments before and after the idle delay segment are adjacent in 
memory the playtime is computed as the sum of all three segments. 
  The last adjacent segments in a sequence in sequence mode or the last adjacent 
segments in a scenario in scenario mode can be shorter than 257 sample vectors in 
total.
