Oscillators
002R features two main digital oscillators per voice (Numerically Controlled Oscillators - NCO),
identified by OSC1 and OSC2 labels, each one with its own Sub-Oscillator.
NCOs differ from the oscillators found in most virtual analogue synthesisers in that they use
a variable sample rate and as such are not band-width limited. This means that a sawtooth
sounds like a sawtooth regardless of the pitch played and results in a very rich sound,
previously only obtainable from classic analogue synthesisers.
1. Wave/PW:
Allow you to choose among 56 different waveforms, ranging from classic
analogue sounds to more unique digital shapes.
2. Note:
Control the tuning of each oscillator in semitones, covering a range from -24 to
+24 semitones.
3. PW:
If the underlying PW switch is on, the oscillator is in PulseWave mode: this means
that now the Wave parameter acts as a pulsewidth control, with maximum value of 63
corresponding to a squarewave.
4. Detune:
This parameter controls the fine tuning of the oscillators, with the maximum
value of 127 corresponding to about a semitone.
5. DeRez:
When this option is On, a down sampling algorithm is active on both the
oscillators. This algorithm adds a good amount of additional high-frequency harmonics, in
order to make the sound brighter (tip: very good with waveforms from 30 to 45).
6. Sync:
When this option is On, the two oscillators are hard-synced. OSC2 is the slave
oscillator: you can detune it or modulate its pitch, but it will always follow OSC1 pitch.
7. SubWav:
This option controls the sub-oscillators behaviour. Each sub-oscillator is linked
to a main oscillator, sounding one octave lower.
•
When the SubWav button is off, the sub-oscillators produce standard square waves.
•
When the SubWav button is on, the sub-oscillators use the same waveforms as the
corresponding main oscillator.
This is a key feature of the 002R, this is more like having 4 oscillators per voice rather
than the traditional 2 oscillators. Combining SubWave and DeRez functions when
creating sounds allows you to create a variety of harmonic contents for the oscillators
