Using KDFX live from the K2500 keyboard
The sliders and wheels on the K2500 keyboard, and the pedals connected to the keyboard, can
be extremely useful with KDFX, if you assign FXMods to the K2500Õs controllers. The ribbon,
for example, can be used in a ÒPitcherÓ FX Preset to change the pitch of the signal, while sliders
and pedals (as we saw in Chapter 2) can be used to control reverb time, ßanger feedback, eq, or
any of the myriad parameters available in KDFX.
KDFX in Setup Mode
If you are playing the K2500 in Setup mode, then itÕs probably a good idea to have KDFX also in
Setup mode, or in Auto mode. This can help prevent confusion that can arise when mixing
modes.
Like Programs, every Setup has a set of FXMod routings associated with it. These are identical
to the routings available in Programs: there are four FXMod pages, three dedicated FX function
pages, and an Import FX page. The procedure for setting up the routings is the same as in a
Program. KDFX settings can be imported into a Setup from either another Setup or a Program.
When KDFX is under Setup control, any FXMods that are in the Programs within the Setup are
ignored. If you have a Program that contains a Studio and FXMods that you would like to use
while playing a Setup, import the KDFX from the Program into the current Setup.
MIDI Control and Setup Mode
YouÕll notice that when you set FX Mode to ÒSetupÓ, FX Chan goes to ÒNoneÓ, and canÕt be
changed. The MIDI receive channel for controlling KDFX is not determined here, itÕs
determined in the Setup itself: itÕs the channel that Zone 1 of the Setup is receiving. Any
incoming MIDI commands on other channels, while they may play
sounds in the Setup, will not
affect KDFX parameters.
There may be circumstances in which you donÕt want KDFX to be in Setup mode while you are
playing a Performance Setup. For example, you may want to have an external sequencer
controlling KDFX, while you are playing along on the K2500 keyboard in Setup mode. Or you
may just want to be able to play in Setup mode and not worry about changing Studios when
you change Setups
In these cases, it makes sense to set the FX Mode to ÒProgramÓ. You will have to set an FX
Channel, and the Program that is in the Zone assigned to the FX Channel will control KDFX. If none
of the Zones are assigned to the FX Channel, then the Setup will not be able to control KDFX.
However, an
external device sending MIDI data to the K2500 on the FX Channel will be able to
control KDFX.
HereÕs an example: say a Setup has three Zones, which are assigned to channels 2, 4, and 6
respectively. If
FX Chan is set to 6, then the FXMods in the Program in Zone 3 will be active. But
if none of the ZonesÕ channel assignments match the FX ChannelÑsay itÕs set to 16Ñthen
nothing you do on the K2500 will control the FXMods. However, an external sequencer sending
on channel 16 will control the FXMods, and the Program that is on channel 16 will determine
what they are.
Using an External Keyboard with Setup mode
As we mentioned in Chapter 2, using a K2500 (or more commonly, a K2500 R ) with an external
MIDI keyboard presents some special situations. If you are not using this conÞguration, you are
advised to skip this section, because it gets a little hairy (unless you are morbidly curious about
such things, in which case, read on!)
