The System - Oberheim OB 12 Operating Manual

OB 12
- OSC ENV: which acts on the oscillators and establishes their behaviour over time, and thus
defines how the pitch will change over time;
- FILTER ENV: which sets how the filters will behave over time and thus how the character of
the sound will change over time;
- AMP ENV: which regulates the behaviour of the amplifier and thus determines how the volume
will change over time;
LFO1: low frequency oscillator used to modulate the signal (when required) on the four main
-
components;
LFO2: like LFO1 but controllable using the [MODULATION] wheel.

In the Timbre operating environment, the user can set up the keyboard modes and pitch, and the
dynamic (Velocity) and Aftertouch controls.
Section 7 of the manual illustrates all the panel controls relating to the Timbre settings. Section 8
contains all the display settings relating to the Timbre operating environment.
To access this operating environment, press the [TIMBRE] key in the MODE&SET-UP section of
the central panel. Once the selection has been made, the LED of the key illuminates and the
following video page appears in confirmation:
The SYSTEM operating environment allows the user to make use of all the utility functions which
are not essential for the purposes of the generation and diffusion of the sound, but which allow
configuration of the whole system (and therefore not of the individual Programs or Timbres) to
individual requirements.
These utilities include all settings on the MIDI (mode, filters, MIDI Program Map, assignment of
Control Changes to the controls, synchronisation, data Bulk Dump), assignment of functions to
the pedals, setup of the digital output, display contrast, swapping, etc.
Refer to section 10 of the manual for all information concerning the System operating environment.
