Mem : Memory Area Id; Pset : Parameter Set Number; Blk : Block Number - Casio PX-320 Implementation Manual

16.3.7

mem : Memory Area ID

Format: 0mmmmmmmB
Specifies the memory area that is the object of the parameter transfer. The following are defined for this Instrument.
Mem
0 User area (rewriting allowed)
1 Preset area (rewriting not allowed)

pset : Parameter Set Number

16.3.8
Format: 0nnnnnnnB (LSB)
This field is a 2-byte (LSB, MSB) value indicating the number of the parameter set (mmmmmmmnnnnnnnB, Binary)
being transferred.
16.3.9

blk : Block Number

This supplementary number specifies which block is the object when there are multiple blocks within the same parameter set.
Format: 0iiiiiiiB (LSB)
In the cases when there are multiple parameters in a category with the same ID (such as the mixer channel volume setting),
for example, the block number required in order to specify the block where the data belongs is indicated as
kkkkkkkjjjjjjjiiiiiiiB (Binary).
When the parameter block has a multi-dimensional array structure, bit 21 of the block number is divided into prescribed
bit fields based on the rules explained below.
Block Bit Field Division
• Case 1
When an array has three or fewer nesting levels and the number of arrays in each dimension is 128 or less, they are assigned
below the three 7-bit fields. Unused regions are filled will zeros.
Example:
parameter [A][B][C]
With a 3-dimensional array parameter that consists of A=8 (3 bits), B=5 (3 bits) and C=10 (4 bits), the block bit fields are
allocated as: Block = 0000aaa 000bbb ccccccc (Binary).
• Case 2
When Case 1 conditions are not satisfied, the minimal number of fields required for each number of arrays is reserved from
the lower bit of the block. Unused regions are filled will zeros.
Example 1:
parameter [A][B][C][D]
With a 4-dimensional array parameter that consists of A=3 (2 bits), B=4 (2 bits), C=3 (2 bits) and D=4 (2 bits) like the one
shown above, the block bit fields are allocated as: Block = 0000000 00000a abbccdd (Binary).
Example 2:
parameter [A][B]
A=3 (2 bits), B=200 (8 bits)
With a 2-dimensional array parameter like the one shown above, the block bit fields are allocated as: Block = 0000000
000aab bbbbbbb (Binary).
