9.1 EDIT PART SETTINGS
193
The main feature of a Program is that it can be subdivided into four Parts, to which one Timbre
each is assigned. This allows you to play a multi-timbre Program and also assign the Parts to
different zones of the keyboard, in order to obtain different sounds (for example, you can play
Parts 1 and 3 in a given zone of the keyboard and Parts 2 and 4 in another position) by simply
using the same Program.
From the EDIT PROGRAM MENU select field 1-PART SETTING; the display will show:
As you can see, buttons [F1]-[F2]-[F3]-[F4] can be used to select the four video pages relating to
definition of the Parts. Here we will describe the first page, which is identical to the later pages and
can therefore be taken as reference for them all.
First of all, under the heading (i.e. where the name of the video page and of the Program of
reference appear) there is a drawing of the OB-12 keyboard which shows the range (the keys
displayed in reverse) of the Part currently selected.
The following parameters are then present:
•
STATUS: activates (ON) and/or deactivates (OFF) the Part in question. If it is disabled, it will
not be possible to play the Timbre it contains. If no other Part is present in the keyboard zone
to which the Part in question is associated, that portion of the keyboard will not produce any
sound.
•
TIMBRE: assigns a given Timbre (displaying its memory location) to the Part.
•
LEVEL: regulates the level of the Part. If LEVEL=0 is set, the part in question will not produce
any sound.
•
TRANSPOSE: sets the transposition of the Part (and not of the keyboard) in a range of ± 12
semitones.
•
LO-KEY: sets the lowest note of the portion of the keyboard associated to the Part. As well as
using the usual data input tools, you can also select the desired value by pressing the keyboard
key itself.
•
HI-KEY: sets the highest note of the portion of the keyboard associated to the Part. As well as
using the usual data input tools, you can also select the desired value by pressing the keyboard
key itself.
N.B.: In order to have a better MIDI compatibility with any eventual connected instrument, LO-KEY
and HI-KEY parameters are setted beyong the real keyboard range. When a given Part is
transposed, the MIDI Note On messages (since the Note Off is sent like Note On with Velocity=0)
relating to the Part concerned will be sent to the MIDI [OUT] port on the basis of the transposition.
Conversely, the Note On messages received by the MIDI [IN] port will not be affected by the
transposition. However, refer to point 10.1 with regard to the settings of the MIDI channels assigned
to the Parts.
