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. OSC SYNC EXAMPLE 1 - OSC2 LOWER FREQUENCY THAN OSC1 OSC 1 (SQR) MASTER OSC 2 SYNC OFF OSC 2 SYNC ON OSC SYNC EXAMPLE 1 - OSC2 HIGHER FREQUENCY THAN OSC1 OSC 1 (SAW) MASTER OSC 2 SYNC OFF • 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-off designed specifically for the DeepMind 12D. 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 Off, or its operational range is from -48.1 dB to 0.0 dB. The default NOISE LEVEL setting is 0ff. 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: OSC 2 SYNC ON OSC SYNC EXAMPLE 1 - OSC2 LOWER THAN 1/2 OF OSC1 OSC 1 (SQR) MASTER OSC 2 SYNC OFF OSC 2 SYNC ON Note: If OSC 2 is lower than 1/2 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 Off. The default program setting is Off. There is also a visualization of the SYNC waveform as shown below. If you press the SYNC switch on and off, you will see the effect on the waveform.

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 1/2 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 Off. The
default program setting is Off.
There is also a visualization of the SYNC waveform as shown below. If you
press the SYNC switch on and off, you will see the effect on the waveform.

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-off designed specifically for the
DeepMind 12D. 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 Off, or its operational range is from -48.1 dB to
0.0 dB. The default NOISE LEVEL setting is 0ff.
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:
