Kenton YP-40 (after Nov 04) - Manual

User instructions for Kenton MIDI retrofit for
YAMAHA YP-40
These instructions are only for YP-40 MIDI retrofit kits produced after 1
st
November 2004
Firmware PF155130 or later
N.B. Different instructions apply to earlier Kenton YP-40 MIDI retrofit kits.
USING THE INTERFACE
Just play the YP-40 as normal. Any notes you play and their velocity, along with any operation of the sustain pedal
will be transmitted on the selected MIDI channel to your receiving device. Program changes can also be sent from
the keyboard in conjuction with the red push button – see below.
When you turn on the YP-40 for the very first time, it will be transmitting information on MIDI channel 1. If you want
to change the transmit channel see below.
USING THE RED PUSH BUTTON TO SEND PROGRAM CHANGES
A short on the red push button enters program change mode. Any key then selects a program change which is
transmitted to your receiving device, you are then automatically returned to playing mode.
For example, a short press on the red push button followed by the bottom note on the keyboard will send program
number 0 (or 1 if your receiving device numbers programs from 1 – 128 rather than from 0 – 127). Whereas a short
press on the red push button followed by middle C on the keyboard will send program number 32 (or 33 if your
receiving device numbers programs from 1 – 128 rather than from 0 – 127). It is not possible to send program
numbers higher than 75 (76).
USING THE RED PUSH BUTTON TO SELECT THE TRANSMIT CHANNEL
Pressing and keeping the red push button pressed for about four seconds or more enters setup mode. After the
four seconds you can release the button. Then press the appropriate key to select the MIDI channel you want to
use, you are then automatically returned to playing mode. On the following page is a list of what each key will do if
pressed during setup mode. The transmit channel is then stored for recall next time the YP-40 is turned on.
TRANSPOSE LEVER (The one already fitted to the YP-40)
When you use the transpose lever of the YP-40, the MIDI information sent to your receiving device will also be
transposed by the same amount. Be aware however that this will also affect the program change and MIDI channel
setting functions (using red push button). To avoid confusion, ensure that the transpose lever is in its central (non-
transposed) position whenever you are going to press the red push button, or at least be mindful of its effect.
RESTORING FACTORY DEFAULT SETTINGS
If you press and hold the red push button while you turn the YP-40 on, the interface will be reset to its default
settings
