7.2.15 SYSTEM SETTINGS

Note: To access successive GLOBAL pages just press the GLOBAL switch again to
cycle through the pages.
In this menu are all the SYSTEM SETTINGS of the DeepMind 12. These include
VERSION NUMBERS of the hardware/fi rmware, settings for the fan speed and
access to the CALIBRATION routines.
To navigate the options in the SYSTEM SETTINGS menu, use the UP and DOWN
switches.
In order to change any of the parameters make sure that the ' < ' symbol on the
respective line is highlighted.
Selected parameters are adjusted using the -NO/+YES switches, the rotary knob
or the fader. The rotary knob has a click which allows very accurate control. The
fader allows rapid adjustment across the full range.
HOST-VER - This is the version number of the host fi rmware.
VOICE-VER - This is the version number of the voice circuit board.
DSP-VER - This is the version of the DSP fi rmware.
BOOT-VER - This is the version of the bootloader used to initialize the synthesizer.
WIFI-VER - This is the version of the WiFI.
FAN-SPEED - This allows you to adjust the fan speed. The fan speed is adjustable
from 0 (off ) to 255 (maximum). Adjust the fan speed to suit your listening
conditions and preference. If the local temperature is high, please make sure
that the fans are not turned off . The DeepMind 12 is equipped with 2 fans, one
internal and one at the rear. At an approximate setting of 40 the internal fan is
running and the rear fan is off .

7.2.16 CALIBRATE

This menu allows you to perform CALIBRATION of the VOICES, MOD WHEEL, PITCH
WHEEL, AFTERTOUCH and PEDAL INPUT.
To navigate the options in the CALIBRATION menu, use the UP, DOWN, switches.
Selected parameters are adjusted using the -NO/+YES switches, the rotary knob
or the fader. The rotary knob has a click which allows very accurate control. The
fader allows rapid adjustment across the full range.
In order to start a calibration routine make sure that the ' < ' symbol on the
appropriate CALIBRATE line is highlighted and press the +/YES switch.
The DeepMind 12 has 12 voices. Each voice has its own LFO, OSC, VCF, ENV and
VCA stages.
The CALIBRATION routine is used for the Voice checking, OSC wave shapes, VCF
self-oscillation, Pulse Width modulation and the VCA bias.
VCF - Unlike many other synthesizers, the DeepMind 12 is capable of
accurate pitch tracking even when the fi lter resonance is pushed to (and
past) the point where the fi lter starts to self-oscillate. When using this self-
oscillating feature of the VCF as a sound source, the VCF calibration ensures
the correct response when playing the entire scale of the keyboard.
The DeepMind 12 VCFs are calibrated at the factory during production.
However, because its fi lters are voltage controlled and can be aff ected
by extremes of temperature, you may need to use the built-in calibration
function to fi ne tune them occasionally. Calibration may also be required
after a fi rmware upgrade or when being requested to do so by an authorised
Behringer support technician.
OSC - The DeepMind 12 OSCs are calibrated at the factory during production.
The oscillators are discrete analog circuits but they are digitally controlled.
Compared to a Voltage Controlled oscillator (VCO), the OSC has far superior
stability, especially when they have a very high frequency, low-jitter master
clock sources, as used in the DeepMind 12. This stage calibrates the slope of
the sawtooth waveform to ensure even volume and pulse-width across the
full range of the synthesizer.
This means that the OSCs should never need re-calibrating except for after
a fi rmware upgrade or being requested to do so by an authorised Behringer
support technician.
