88
Local Control
This turns local control of the PC88 on and off. This function is very important in a large studio.
HereÕs why:
If the PC88 is the master keyboard for a sequencer and at the same time is acting as a multi-
timbral instrument, itÕs essential that the performance section (the keys and controllers) and the
sound-producing section (the voice banks) be independent from each other. That way, when
you are playing a part on the keyboard into the sequencer that is meant to be heard on a
different
instrument, the PC88 doesnÕt play the same part using an internal sound, and utterly
confuse you. This Òde-couplingÓ of the two parts of the instrument is known in MIDI parlance
as ÒLocal Control OffÓ.
When
Local Control is on, the instrument plays the sounds that you are playing on the keys.
When it is off, the keys do not play the local sounds. However, the keys are still transmitting
MIDI data Ñ itÕs the equivalent of setting the Destination for every Zone to MIDI only. Also, the
PC88 is still
receiving
data as well, so that incoming MIDI from a sequencer will make the
instrument play. If the sequencer has a Òloop-thruÓ function, as most do, then you can play the
PC88 keyboard and hear the PC88 at the same time, with the sequencer determining which
channels (and which sounds) you are hearing.
Clock
This parameter and the
Transmit Clock
parameter deal with how MIDI Timing Clock messages
are handled. The
Clock
parameter determines whether the PC88 will generate its own MIDI
Clocks, or instead will listen to external Clock messages.
If it is set to
Internal
, then the tempo of the Arpeggiator, as well as the tempo of any sequencer,
drum machine, or other variable-tempo device connected to the PC88 can be controlled from
the PC88Õs own Tempo parameter. This, in turn, can be assigned to a slider, pedal, or wheel.
If Clock is set to
External
, the Arpeggiator will follow Clocks coming into the PC88 from an
external source. If there are no Clocks at the PC88Õs MIDI input, the Arpeggiator will not play.
Transmit Clock
The
Transmit Clock
parameter determines under which circumstances the PC88 will send
Clocks out the MIDI Out jack (it has no effect on clocks coming in). The choices are
Off
(never);
On
(always); and
Seq
(for ÒSequenceÓ Ñ send Clocks only after a Start or Continue command,
or when the Arpeggiator is turned on; and stop sending when the Arpeggiator is turned off, or
a Stop command is issued.) If the PC88 is sending out MIDI Clocks, make sure the devices
receiving them have
their
sync parameter set to ÒExternalÓ.
Touch
Touch
lets you adjust the overall feel of the keyboard. You can further modify the keyboard
response (per Setup) with the
Velocity
parameters.
Effects Change Mode
As weÕve seen, each Internal Voice has an Effect assigned to it, and so does each Setup. Effects
can also be changed from the front panel, using the Effects buttons and/or the Effects editor
