CONNECTIONS

MIDI In

Plug your MIDI pedal, controller or sequencer`s MIDI Out into here. The LD-2 has no MIDI thru, so it will
need to be at the end of your MIDI chain, or fed from a thru box. Note that if you are using several MIDI
devices “daisy chained” together, data may get corrupted to the devices at the end of the line. Best
practise is to use a “Thru Box” if you are using more than 3 devices chained together.

DC IN 9-12V

Plug the power adapter into here. The unit will take an adapter with an output in the range of 9-12V either
regulated or unregulated. The socket is a 2.1mm type with centre positive. Do not use an adaptor with an
output voltage higher than 12V, and the LD-2 must not share an adaptor with any other device. Failure to
observe this will invalidate your warranty, and will probably damage the other device, the LD-2 and/or the
power supp

ly.

DISPLAY

The display has two types of readout. Firstly numbers are displayed in numeric format. This can be either
0-127 as used by MIDI or alternatively 0-20. Secondly, there is a 20 segment bar reaout where a value of
zero will show no bars, and a value of 127 will show all bars, with intermediate values showing a
proportionate number of bars.

USING THE LD-2

First connect the supplied power supply to the DC input socket on the left side of the unit, then connect
your MIDI signal cable to the MIDI In socket.

When power is applied to the LD-2, the words KENTON LD-2 will scroll across the display, then three
horizontal bars will show, indicating that no valid message has been received yet.

The factory default is to display the value of any message sent by controller #7 on MIDI channel #1.

CHANGING THE CONTROLLER & MIDI CHANNEL

To change the MIDI message being displayed, use a small screwdriver or matchstick (or similar) to press
(then release) the learn button. The display will then show the letters “L r n” for learn. The learn button is
deliberately recessed to prevent accidental re-assignment.

The next controller (or program change) message received on any MIDI channel will be stored, so that
any subsequent message received from that controller on that MIDI channel will be displayed both on the
7 segment display, and on the bargraph.

The controller (or program change) and channel information is saved in non-volatile memory, so the unit
will “remember” its assignments for the next time it is used.

Because MIDI program changes are either displayed 0 to 127 or 1 to 128, it is possible to select either
mode.

1) press the recessed button to put the unit into learn mode

2) press the program change button on your synth with the number "2" on it. This will either be the 2nd or
3rd button depending which scheme your keyboard uses.

- if your synth goes 0-127 then the display will show 0 (zero) when you do this to indicate 0-127 mode

- if your synth goes 1-128 then the display will show 1 (one) when you do this to indicate 1-128 mode

- if the display is not the mode you want, just use the next button up to program

The unit will then be ready to display program numbers on the MIDI channel you used to program it with.
LD-2s with firmware earlier than #1126 cannot display program changes.

CHANGING THE NUMERIC DISPLAY MODE

To change the display mode to 0-20 or back to 0-127, hold the learn button in for a few seconds. At first it
will display L r n (learn), but after several seconds it will show 20 for 0-20 mode or 127 for 0-127 mode. If
you continue to hold the button in, it will continue to toggle between the two modes. When the mode you
want to use is displayed, release the button and the unit will be ready to use again. This setting is also
stored in the non-volatile memory. If you learn program change, then display mode will be reset to 0-127.
