8. EDIT TIMBRE
164
The Edit Timbre function allows the user to set all the parameters relating to the chain for generation
of a given sound. Section 7 “Using the panel” has already illustrated the functions of all the
controls needed to create the main parameters of a sound. The display pages allow you to define
additional settings for total control of the editing of a timbre. This section explains all these settings.
However, anyone who has decided to skip section 7 is advised to read that section of the manual
before proceeding with this section.
For the procedures for selection of the menus and parameters, refer to point 6.1 – “Play Program”.
From any video page, press the [TIMBRE] button in the MODE&SET-UP section of the front
panel. You have now selected the TIMBRE operating environment and the display will show:
The video pages which can be recalled by selecting the INFOS and SCOPE folders have already
been described in point 6.2.
We will now examine all the procedures for modifying the sound generated by the OB-12.
Select the EDIT function; the display will change to:
This video page shows the menu for editing a Timbre. It consists of the following sections:
1-LFO1: regulation of the parameters relating to the first low frequency oscillator.
2-OSC.COMMON: regulation of the common parameters of Osc.1 and Osc.2.
3-OSCILLATOR 1: setting of the parameters for control of oscillator 1.
4-OSCILLATOR 2: setting of the parameters for control of oscillator 2
5-FILTERS: regulation of the parameters relating to the two filters.
6-AMPLIFIER: regulation of the amplifier setting parameters.
7-LFO2: setting of the controls of the second low frequency oscillator.
8-MODE: setting of the keyboard modes, unison and oscillator transposition.
9-CONTROLLERS: setting of the Velocity, Aftertouch, Ribbon Controller and [PITCH] and
[MODULATION] wheels.
As you will see, when modifications are made to the parameters of the various sections, each
change is shown on the display, not only numerically but also in graphic form, to give a full
understanding of what is being adjusted.
To make the various sound generation sections clearer, the points which follow will not appear in
the same sequence as on the panel and on the display from the EDIT TIMBRE MENU video
page; instead, reference will be to their position within the generation chain (and therefore as
