IEM User Manual
Program Changes:
When the IEM is set to receive on one or all of the MIDI channels, it will recognize a Program
Change command. If the number is legal (i.e., within the device's range of selectable programs)
the IEM will respond by changing to the new program. MIDI sends Program Changes 0 through
127. The IEM begins its program numbering with 1, thus Program Change 0 will select program
1. The IEM also allows the user to 're-map' the Program Change commands so that Program
Change 0 could call program 60, if so desired.
The IEM has the ability to dump an individual Program as a MIDI number other than its own.
This is particularly useful in cases where you need to perform Program dumps from one IEM
to another, and you don't want to overwrite the corresponding Program number in the desti-
nation unit. To dump an individual Program, do the following:
1. Enter the “Utility” menu by pressing the UTILITY button once.
2. Press NEXT PAGE button until page 5 is reached.
3. Use the DATA WHEEL to select which program you would like to dump.
4. Press the DATA WHEEL to change the cursor location to the next selection.
5 Select the name of the preset you would like to dump.
6. Press the UTILITY button to start the dump.
About SYSEX Dumps
The IEM allows you to use MIDI to archive the settings in your unit or even settings of each
individual setup. This is done through MIDI System Exclusive data protocols. System Exclusive
data, or SYSEX as it is often called, can be shared between two IEM’s by simply connecting the
MIDI Out of one IEM to the MIDI In of the other. To ensure data integrity, the two IEM’s should
be using the same software version (the version is displayed when the unit powers up). Data
can also be sent to an external MIDI recording device, such as a MIDI sequencer or a comput-
er outfitted with a proper MIDI interface. Once the data is there, it can be sent back to the IEM
to restore settings to their archived values.
System SYSEX Data: The BULK DUMP option allows a complete system exclusive dump of the
entire contents of the IEM’s memory. This includes all user Programs, Utility, and MIDI config-
urations. To perform a system exclusive dump of the entire contents of the memory, do the fol-
lowing:
1. Enter the “Utility” menu by pressing the UTILITY button once.
2. Press NEXT PAGE button until page 6 is reached.
3. Press UTILITY button to dump the entire contents of the IEM’s memory.
A/D Calibrate
This page of “Utilities” is a calibration section for the analog to digital converter chips. To cal-
ibrate the converters, first turn the input controls of the IEM fully counter-clockwise (-
∞ ).
Calibrations performed with these controls open at all could result in inaccurate calibrations,
giving the IEM poor processing performance. After the input controls have been turned to the
