=> R0 = sample number (1-64)
<= R0 = pointer to 22 byte block (not terminated) containing sample name (or a 0 byte, if no sample name)
R1 = sample length (in bytes)
R2 = repeat offset (bytes from start of sample)
R3 = repeat length (in bytes)
R4 = default volume (0-64)
R5 = fine tuning value (-8 to +7)
R6 = address of raw sample data (logarithmic format)
This SWI allows you to read information from the QTM sample table, which contains up to 64 samples. Non-existent samples will return zero in R1-R6, and R0 will point to a 0 byte.
Note: Because only samples 1-31 are used by songs, samples 32-64 can be used for sound effects (in games etc.) and can be registered separately, using QTM_RegisterSample.
V flag set if sample number is out of the range 1-64 or song not loaded
