EUROPA SHAPESHIFTING SYNTHESIZER177
Envelope 3-4
This is a special mode where you can manually draw your waveforms in the Envelope 3 and Envelope 4 windows
and then gradually crossfade between the drawn waveforms using the Shape knob. See “Using the Envelope 3
and Envelope 4 curves as Sound Engine waveforms” for information on how to draw your own waveforms.
FM > FM Ratio (1:1, 1:2, 1:8, 2:1)
These are frequency modulated sine waves with different frequency ratios between the carrier (C: ) and modulator
( :M) signals. Set the frequency modulation amount with the Shape knob.
FM > FM Feedback
A pure sinewave signal at Shape=0% gradually fed back internally at an 1:1 ratio. The feedback signal is filtered
before fed back to the carrier signal. If you modulate the Shape parameter from e.g. an LFO you will get a similar
result as when using the FM FB Noise waveform without Shape modulation, see “Noise > FM FB Noise” below.
•Noise > S/H Noise
A sample & hold modulated noise. Change the sample & hold rate with the Shape knob. If you play high up on the
keyboard at high Shape values, you get a kind of “pitched noise” sound.
q To get white noise, set Shape to max, set Oct to -1 and turn Kbd to 0.
Noise > Perlin Noise
A pure sinewave signal modulated by low frequency noise. At Shape=0% the noise has its lowest frequency and
at Shape=100% the noise frequency is higher (but still low-frequent). The character of the signal is similar to the
Band Noise in the Thor synthesizer.
•Noise > Bit Noise
This generates a random lo-fi “digital” bit noise. At Shape=0% the signal is completely silent and with increasing
Shape values the signal is modulated faster and in a wider frequency range.
Noise > FM FB Noise
A pure sinewave signal at Shape=0% gradually fed back internally at an 1:1 ratio. The feedback signal unfiltered
before fed back to the carrier signal which gives the signal a noisy character.
q To get a cleaner FM signal, use the FM Feedback waveform, see “FM > FM Feedback” above.
Noise > Freeze Noise
This signal produces a range of noises, from tonal noise up to almost white noise, by amplitude modulating the sig-
nal’s partials with noise.
Wave Tables >
The Wave Tables sub-menu contains a selection of very useful wave tables. Each wave table features eight wave-
forms that you could crossfade between with the Shape knob.
User Wave/User Wave Smooth
The User Wave options let you use the external sample you have loaded in the User Wave section (see “The User
Wave and Mixer section”). The oscillator then generates and plays back wavetables (grains) of that sample. The
“User Wave Smooth” algorithm uses a crossfaded loop within each grain, which produces a smoother character to
the sound. Set the playback position in the sample with the Shape knob. Modulate the Shape parameter, for exam-
ple from a negative Envelope ramp, for continuous movement in the sample.
Shape
D Turn the Shape knob to change the shape of the currently selected waveform.
The wave shapes are shown in the display above and are updated in real-time according to the current Shape set-
tings.
Shape Modulation
D Click the Shape Modulation Source box to bring up a menu of the available modulation sources.
The “Inverted” sub-menu contains inverted variations of all modulation sources.
D Set the modulation amount with the Shape Modulation Amount knob.
