MIDI SPECIFICATION
MIDI SYSEX COMMANDS
For system exclusive commands, the following format is used:
F0 System Exclusive Status Byte
18 E-mu ID Byte
0C Product ID Byte (will also respond to ID 04 - Proteus)
dd Device ID Byte
cc Command Byte
... Data Bytes
F7 EOX
SysEx Editing
Preset and setup parameters may be edited individually using system
exclusive commands. The preset being edited is the active preset (the
preset on the basic or global channel and the one which is shown in the
LCD). The value of a given parameter may be changed by sending a
parameter value command. The value of a parameter may be read by
sending a parameter value request, to which the machine will respond by
sending back the parameter value. Please note that there is only one
edit buffer
All SysEx bytes are displayed in Hex, unless specified other-
wise. All comment numbers are displayed in decimal, unless
specified otherwise.
Two MIDI bytes (lsb, msb) are required for each 14 bit data word. Bits 0-
6 are sent first, followed by bits 7-13 in the next MIDI byte. All data
words are signed 2's complement values with sign-extension out to the
most significant bit (bit 13). This convention applies to all data words,
regardless of the parameter's value range.
Preset data may also be transmitted or received in a single block (one
complete preset) using system exclusive commands. A preset data request
may be issued by a host computer, to which the machine will respond
sending the data block for the requested preset. Conversely, the com-
puter may send new preset data which will replace the specified preset
currently in the machine. Additionally, a front panel command will
transmit one or all user presets for backup onto an external sequencer.
These presets may be restored by simply playing back the sequence into
the machine.
Warning: When transferring preset banks and tuning table data back
and forth from Morpheus to a computer, the data should be recorded as
you would a regular sequence. Sending the data in one huge chunk will
clog the input buffer on Morpheus unless a time period of approxi-
mately 100 mS is inserted between each preset. The SysEx Packet Delay
feature in the Master menu can be used to slow down the data rate
when the computer's input buffer is being clogged.
••• Morpheus will receive
Proteus presets (if enabled in
the Master menu), but will fill
in the extra parameters with
default values and set
instruments to “None”.
▼ There is only one edit
buffer each for the current
preset, the current
hyperpreset, and the current
midimap.
Only one preset, hyperpreset
or midimap can be edited at
a time via SysEx commands
and changing the current
preset, hyper or midimap
erases the associated edit
buffer.
