Signal flow The picture below shows the basic signal flow in Europa: Europa signal flowchart. • The “hearts” of Europa are the three Sound Engines I, II and III. • First in each Sound Engine is an Oscillator, which generates the basic audio signal. The oscillators in Europa are extremely powerful and flexible. Besides all the basic “analog” waveforms, the oscillators can also generate a vast variety of wavetable waveforms, physical modeling signals and other types of unique signals - and also your own samples! The signals can also be continuously transformed into various shapes. • The Oscillator signal can be modified by the two Modifiers. The Modifiers feature a huge amount of algorithms that can modify the Oscillator signal in various ways. • The signal from the Oscillator is routed to the Spectral Filter. The Spectral Filter affects the partials of the signal. The algorithms could be various types of filters - or special purpose signal processors. • The signal from the Spectral Filter can then be routed to the Harmonics processor. The Harmonics processor modulates the harmonics in the signal, for example introducing ensemble or stretch effects. • The signal from the Harmonics processor can then be routed to the Unison module. This module can generate various types of unison chorus effects, to make the sound really fat and wide. • The signals from the Sound Engines are then routed to the Mixer, where you can set the mix between the three Sound Engine output signals and also pan the signals individually. • The mixed signal is then routed to the Filter, Amp Envelope and then, via the Multi FX section, to the stereo outputs. • The remaining sections in Europa (Envelopes 1-4 and LFOs 1-3) can be freely assigned to modulate destination parameters via the Modulation Bus section.
