1Eigenharp Terminology
What is a mode key?
The mode keys allow you to navigate your way around the Eigenharp,
and access its various features quickly and easily. For example mode
keys are used to choose sounds, access controls for drum loops and
recorders, or choose dierent keyboard layouts.
This is a quick introduction to some of the terminology used in this
reference guide. Such terms as mode key, split and keygroup are used
throughout so it’s handy to become familiar with their meanings.
What are keygroups and splits?
It is possible to divide the Eigenharp’s keyboard into independent
groups of keys which we call keygroups.
You can access any of the Eigenharp’s features from any of the
keygroups, and each keygroup can be doing something dierent;
for example you could use one keygroup to play bass, whilst another
keygroup controls drum loops.
A split is the name we give to an arrangement of keygroups.
For example the diagram on the right shows a split with the
keyboard divided into three keygroups.

Keygroup Mode Key layout
When you press a keygroup’s mode key the following options will show.
This is the same for all keygroups wherever they are on the keyboard.
Below is a summary of what each function is:

9Diagram A - Drummer controls
Diagram B - Recorder controls
Each of the keys labelled 1-12 represents a drum loop – pressing any of
these will turn the loop on or o. To play drum loops the metronome
must be running.
The recorder controls allow you to set how many bars you
will record for, unplay recordings and cancel recordings.
To record you must rst start the metronome, please see the
drummer controls for more detail. Each numbered key in the
diagram represents the number of bars you will record for, e.g. key
1 = 1 bar, key 2 = 2 bars, key 3 = 3 bars, key 4 = 4 bars, etc.
The key marked ‘U’ will unplay all recorded loops that are currently
playing. The key marked ‘C’ will cancel all armed recorders. Please
be aware that once you unplay a recording it will be deleted. To
stop recordings without deleting, use the Scheduler.
The key marked ‘O’ toggles overdub mode. Turned on, additional
recordings for the same instrument create new takes that play
simultaneously. Also, the‘unplay’key deletes only the last take,
allowing loops to be built up and tore down with one instrument.
Once you have selected how many bars you would like to record
for, you must arm the recorder. The record arm key is located
at the bottom of your playing keygroup, this key will arm the
recorder for your currently selected instrument.
Next to the record arm key you have an unplay/cancel key. Note
that these keys will only appear once you have selected an
instrument. Please refer to the Keygroups diagram below.

A note about Scale and Tonic controls
Scale controls Tonic controls
Each keygroup can have its own scale and tonic.
As you can see in the diagram, we have a second mode key
(scale/tonic mode key), this allows you to select which
keygroup you are choosing the scale and tonic for.
Press and hold this key and you will see a group of lit keys
which represent the available keygroups – the green key
is your selected keygroup. This view is generic for both the
Scale and Tonic controls. Choose key 1 in the diagram to
access the scale/tonic controls for keygroup 1, key 2 for
keygroup 2 etc., through to keygroup 6.
Choose the key marked ‘Global Scale/Tonic’ controls to set
the scale/tonic of all keygroups simultaneously.

Advanced controls (On split 1)
The advanced controls are accessed on Split 1 by pressing keygroup 1’s mode key.
The layout of the advanced control keys corresponds with the layout of the instruments and
standard controls that become available when you hold down a keygroup’s mode key.
There are no advanced controls for the recorder and scheduler hence the gap between the key
labelled 1 (advanced drummer controls) and the key labelled 2 (advanced scale controls).
