Here’s a look at the pitch shell. For the most part, it has to do with all things frequency related.
- On/Off turns only the Pitch Envelope on/off
- Pitch Envelope Amount sets the intensity of the pitch envelope.
- Spread is a stereo widening effect that slightly detunes the sound on the left and right channels giving it a wider chorus-like effect.
- Transpose works as a global transposition for all of the Oscillators.
With the pitch shell selected, Operator’s display window shows you the pitch envelope, as well as some auxiliary Mod destinations similar to what the LFO shell had to offer.
Let’s add some pitch envelope to our patch. Try these settings in the Pitch Display:
- Attack: 0.00 ms
- Decay: 447 ms
- Sustain: 0 st
- Release: 189 ms
- Initial: +5 st
- Peak: +5 st
- Destination A : Oscillator A, B, C, D
- Destination A Amount: 100%
And in the Pitch Shell:
- Pitch Envelope: On
- Pitch Envelope Amount: 100%
- Spread: 70%
- Transpose: 0 st
Here are images of the pitch display and pitch shell with our current settings:
This is a good place to try playing with the Time parameter in the Global Shell. Have a listen to this audio file. I’m playing a C minor chord first with our current patch settings (between C3 and D4 on the keyboard), then a second time with the Time parameter set to 100% and a third time with it at -100%.
Try playing this sound with the time set to 100% or -100% between C0 and D2 on the keyboard. You’ll get some great percussive or sustained bass sounds.
A few notes on Digital and Analog Synthesis
A common misconception among beginner musicians / producers is that an analog synth is the same as a hardware synth. This is not true.
The basic difference between digital and analog synthesis is that the oscillators and signal path in analog synths are… analog. What does that mean? It means that the oscillators are controlled by voltage – electricity. The same goes for the filter, envelopes, etc. Digital synthesizers, on the other hand, “calculate” a waveform and then play it back. Digital synthesis is more stable than analog and can create extremely complex sounds because the possibilities are often limitless, but analog synths often (not always) sound thicker and warmer.
