OB 12
DETUNE FINE: regulates the fine transposition of the three timbres in hundredths. This
transposition is applied to the timbres as for the DETUNE COARSE parameter.
FINE RND INFL.
three timbres (specified using the (DETUNE COARSE and DETUNE FINE parameters) will
be modified.
You can now use the [F3] associated to the OSC.SHIFT folder to display the video page relating
to the transposition by octaves of the two oscillators individually. This allows you to use the two
oscillators transposed by up to four octaves apart, creating deeper, more complex sounds, to
play beyond the keyboard range (in both bass and treble direction) and to use different pitches in
the various Parts which make up a given Program (to allow this, the TRANSPOSE parameter
associated to the Part in question can also be used).
The video page consists of the following parameters:
OSC 1 SHIFT
([OCT-] and/or [OCT+] with [OSC SHIFT] on OSC 1)
of the first oscillator in a range of two octaves.
OSC 2 SHIFT
([OCT-] and/or [OCT+] with [OSC SHIFT] on OSC 2)
of the first oscillator in a range of two octaves.
N.B.: When the oscillators are transposed, the MIDI Note On and Note Off messages received by
the MIDI [IN] port will be played on the basis of the transposition carried out.
Conversely, the Note On messages (since the Note Off is sent like Note On with Velocity=0) sent
to the MIDI [OUT] port will not be affected by the transposition.
Thanks to the Velocity and Aftertouch-sensitive OB-12 keyboard, the CONTROLLERS section of
the EDIT TIMBRE MENU allows specific generation control parameters to be assigned to the
Velocity, the Aftertouch and the Ribbon Controller, and enabling and disabling of the [PITCH]
and [MODULATION] wheels.
N.B.: the Ribbon Controller, the Velocity and the Aftertouch are controlling the assigned parameters
according to the value of the parameter when assigning a parameter with 0 value, the concerning
control will not have any sound variation
From the EDIT TIMBRE MENU select field 9-CONTROLLERS and the display will show the video
page relating to the assignment of parameters to the Velocity.
The Velocity (dynamic) is the speed at which the keyboard key is pressed and released. This
function therefore allows you to play the keyboard keys in a way which gives extra expressiveness
to the timbres, without having to use the panel controls. Normally the note velocity is associated to
the signal level, but using this function you can assign the cut-off frequency, for example, to the
Velocity, in order to extend the spectrum of the timbre being played in relation to the force with
which a key has been pressed. So in short, the huge advantage of this function is that several
parameters can be controlled without having to take your fingers off the keyboard.
