8.3.9 OSC SYNC SWITCH
• The SYNC switch controls the synchronisation of the oscillators.
The OSC 1 pitch is set by the keys that you play, and the OSC 2 pitch may be
tuned to (or detuned from) this frequency. By applying hard synchronisation
of OSC 2 to OSC1, every time the OSC 1 cycle starts again, the OSC 2 will be
re-triggered, regardless of its position. If OSC 2 is tuned to a lower frequency
than OSC 1 it will be re-triggered before it completes an entire cycle, and if it
is tuned to a higher frequency it will be re-triggered during a later cycle. This
ensures that the OSCs are playing at the same frequency, however the
irregular cycle of OSC 2 can create complex timbres and rich harmonies.
Note: If OSC 2 is lower than ½ of the frequency of OSC 1, then there will be
no output from OSC 2 when SYNC is ON because the waveform will never
reach its negative cycle.
The OSC SYNC option can be On (the SYNC switch is illuminated) or O. The
default program setting is O.
There is also a visualization of the SYNC waveform as shown below. If you
press the SYNC switch on and o, you will see the eect on the waveform.

8.3.10 NOISE LEVEL FADER
• The NOISE LEVEL fader controls the LEVEL of the internal NOISE signal.
The noise generator is implemented using analog circuitry and creates
pink noise with a low frequency roll-o designed specically for the
DeepMind 12. The noise generator is commonly used with non-pitched
sounds or non-pitched components of a sound, for example a snare drum or
an atmospheric sound.
Pink noise contains equal amounts of energy in each octave. As human
hearing is roughly logarithmic, this type of noise sounds as if it has an equal
amount of all frequencies, and it produces a rushing sound similar to that of
a waterfall.
The NOISE LEVEL can be set to O, or its operational range is from -48.1 dB to
0.0 dB. The default NOISE LEVEL setting is 0.
The fader position, current value and stored value for the NOISE LEVEL fader
is shown on the PROG screen. There is also a visualization of the noise signal
as shown below:
