Mutable Instruments ambika User Manual

SysEx
Ambika can receive and transmit settings in system exclusive format. The messages all share the
same format:
0xf0 (SysEx)
0x00 0x21 0x02 (Mutable Instruments Manufaturer ID)
0x00 0x04 (Product ID for Ambika)
Command
Argument
Payload
Checksum
0xf7 (End of SysEx)
Command
indicates what the receiver should do with the data in the
payload
block, and
argument
is
a byte that might contain an additional piece of information about what to do with the data.
Payload
is a sequence of bytes in nibblized form. For example, the sequence
0x80 0x56 0x13
is
transmitted as
0x08 0x00 0x05 0x06 0x01 0x03
.
Checksum
is equal to the nibblized-sum, modulo 256, of the bytes. In the example above, the
checksum is equal to
0x80 + 0x56 + 0x13 = 0xe9
and is transmitted as
0x0e 0x09
.
Data structure dump
When transfering patch/sequence/program/multi data to Ambika,
