How To Set Up The Volume Level For The Bass And Lower Preset; Selecting The Midi Channels For Reception And Transmission; Parameter And Functions Controls Through Standard Midi Cc - Oberheim OB3 SQUARED Operating Manual

3.3 How to set up the Volume level for the Bass and Lower preset sections
To set up the Volume level for the Bass and Lower section, proceed as follow:
• Bass Section: Keeping pressed the "Bass" (preset) button, adjust the volume level
through the "Master Volume" knob
• Lower Section: Keeping pressed one of the "Lower presets" push buttons, adjust the
volume level trough the "Master Volume" Knob.
Once you have set up the volumes, you should set up the Master Volume to the original
position as it controls the general volume of the instrument.
3.4 Selecting the MIDI channel for reception and transmission
To select the MIDI channel for reception/transmission, press the MIDI key (the LED in the
key illuminates) and then the RX/TX key.
Referring to the pink identifiers screen-printed on the instrument keys, select the required
channel from 1 to 16 (the LED of the key pressed flashes). Press the MIDI key again to exit
and make the selection operational.
The channel selected will refer to the UPPER section only. In case of operating modes
2 and 3, bear in mind that the MIDI channels for the LOWER and BASS sections are
derived from that set for the UPPER section in accordance with the following rule:
LOWER midi channel = UPPER midi channel + 1
BASS midi channel = UPPER midi channel + 2
for example:
With UPPER CH. = 1 ---> LOWER = CH.2 and BASS = CH.3
With UPPER CH. = 7 ---> LOWER = CH.8 and BASS = CH.9
