Use this command to request the contents of an arbitrary block of RAM, up to 32 bytes long. Command is
equal to 0x1f (31). Argument is equal to the size of the requested block. The two bytes of payload indicate
the address to read (16-bit, little endian address). For example, to retrieve the 4 bytes at addresses 0x3ac
.. 0x3b0, the sysex string would be:
Use this command to transfer arbitrary data into Ambika's RAM. Command is equal to 0x0f (15). Argument
