It is important not to confuse the words 'sample' and 'waveform'. You assign a 'waveform' to an element and that 'waveform' might contain several 'samples'. A 'sample' is somewhat analogous to a single WAV file. Specifically you do NOT assign a 'WAVE' file to an element - you assign a 'waveform'.The Montage exposes most of the info you are asking about. Go to the Edit page of, say, a piano sound, and to use your example values at the top of what I quoted, you don't have to guess or use your ears, the screen will show you that it used one sample for velocities 1-20, another one for 21-40, and so on.
What that screen shows you is that is uses one WAVEFORM for velocities 1-20, another one for 21-40, and so on. Each waveform can, and often does, contain multiple key banks and samples.
The top display on page 313 of the reference manual illustrates the difference between a 'waveform' and a 'Key Bank' - a key bank is roughly the same as a single WAV sample.
That display shows ONE waveform that is comprised of FIVE key banks. And each key bank has its own velocity limits and note ranges. In some cases (e.g. banks 2 and 3) the note ranges overlap. The velocity will be used to determine which of banks 2 and 3 will be used for a given note in the indicated note range.
It is the information in this diagram that SampleRobot can NOT access.
Now compare the display on page 307 with the bottom display on page 313.
Page 307 shows the edit page for element 1 of part 1. The name of the 'waveform' is 'CFX v09 St'. That page does indeed show parameters that the user can set for Elem Vel Limit, Elem Note Limit and Center Key. But those parameters are used by the OS to determine the conditions under which the element (and thus the CFX v09 St waveform) will receive Key events.
If those conditions are met then the actual CFX v09 St 'waveform' will be examined to determine what keybank and sample to use to feed the tone generator. That is a preset waveform so you can NOT edit it.
Page 313 shows the edit page for a User created waveform named 'Waveform1'. Notice that it is showing Keybank 1 and that the keybank also has Vel Limit, Note Limit and Center Note (Note - not Key as before). These parameters are directly associated with the actual WAV file that is used to create this key bank and will be used to determine the conditions under which this particular WAV file will be called upon as a source for the tone generator.
The waveform banks, and each banks associated parameter values comprise the 'waveform'. Thus a single 'waveform' can contain many banks and WAV samples. But it is a 'waveform' that is assigned to an element - not an individual 'sample'.
The individual banks and their parameters are INTERNAL to the 'waveform' and can't be seen on an edit screen or by SampleRobot.
It is this 'internal' data I was referring to that I said SampleRobot can't access. Those internal parameter values are READ ONLY for preset waveforms and are HIDDEN from view.
So although you can see the Vel Limit, Note Limit and Center Key values on the element edit screen you can NOT assume they are the same as the values INSIDE the waveform banks. They might be the same as the values for ONE bank of the waveform but the waveform could contain many other banks with different parameters.
GOTCHA! - that is a perfect example of why someone with inside knowledge of the internal waveform structure and parameters can configure elements and use parameter values that correctly map to the internal structure of the waveform they want to use.
And why an ordinary user can run into trouble trying to use preset waveforms when they don't know, and can't access that HIDDEN parameter information.
SUMMARY - SampleRobot can NOT access the Vel Limit, Note Limit and Center Note parameter info hidden in the waveform banks. Nor can it access the Volume, Pan, Tune coarse or Tune Fine parameters (which can also turn you upside down) you also see on page 13 of the doc.
