Operating Instructions
Insert the output plug from the supplied 9VDC AC adapter into the power jack at
the top of the IHM, or make sure a working 9V battery is installed in the unit.
The IHM must be powered to pass signal, even in bypass. Connect an instrument
cable from your guitar to the INPUT jack. Connect an instrument cable between
the OUTPUT jack and a suitable amplier. Click the footswitch to engage the IHM
(the illuminated MOMENT button should be off). The red LED lights to indicate
that the unit is active. Start with MIX and VOL knobs at noon (50%)
The IHM operates in two distinct modes: Intelligent Mode and Polyphonic
Override Mode. When lit, the POLY-OVERRIDE button indicates that Polyphonic
Override is enabled. With this button off, the IHM is in Intelligent Mode. Press
and release the POLY OVERRIDE button to toggle between the two modes.
INTELLIGENT MODE
In Intelligent Mode the IHM generates diatonic harmonies in a set key based on
single notes played on your instrument. Playing multiple notes or chords will
not work well in this mode. Note: It is very important that your guitar be in tune
(based on A440) for the IHM to work properly in this mode!
Setting the Key
The key is set by the top-left seven-position knob in conjunction with the two toggle
switches to its right. If that knob is set to “C” and both knobs are set to the downward
position (natural, and MAJ) the key is set to C major. If the two toggle switches are
moved to the upwards position (#, and MIN) the key is now set to C# minor.
Selecting the Interval
The harmony interval is set by the bottom-
right eleven-position switch. The intervals are
listed in the chart on the right.
The exact note the IHM generates depends on
the key and interval settings along with the
exact note played. For example, with the key
set to C and the interval set to a 3rd up, if a C
note is played, the IHM will generate an E note,
a major third up from C. If a D is played with the
same settings, the IHM generates an F, a minor
third up from D. This is because in Intelligent
Mode the IHM produces diatonic harmonies,
harmonies that are within the set key.
Secondary Interval Options
When in Intelligent Mode, there are two
additional options for the last three interval
positions: 9, 10, and 11, each of which
generates two harmony voices. To access
