3.2.2 Paraphonic Operation
You probably know the difference between a monophonic and a polyphonic synthesizer.
While a monophonic instrument will only ever produce a single note, a polyphonic
synthesizer will allow you to play multiple notes simultaneously. This is basically also
possible with the DELTA CEP A - but all voices share one filter, one envelope and one VCA.
For better differentiation, a distinctive name has been introduced for synthesizers with
these properties: ‘PARAPHONIC’. Most monophonic synths with a paraphonic playmode
have only two oscillators. By activating the paraphonic mode, one can play two keys to
produce two different notes simultaneously. Each note is running only one oscillator, which
makes the sound very static.
With the DELTA CEP A, this is fundamentally different. Since the Swarm oscillator can
produce up to 8 oscillator clones, a chord of up to four voices can be played with two
oscillators per voice, making chords sound more alive. Especially with the saturation stage
in front of the filter paraphonic voices show advantages, because a saturation level
behaves very dynamically when the number of voices (and thus the level at the entrance of
the saturation level) changes. This can be used creatively to great effect.
If you press the [PARAPHONIC] key, you will notice that there are two different paraphonic
modes. The LED above the [PARAPHONIC] button lights up either yellow or green -
depending on which setting is active when you press the button. The difference between
the two modes is related to the control of the envelopes.
PARAPHONIC 1 (YELLOW): Each note that appears at the MIDI input triggers the
envelope. Since all the oscillators share a filter and a VCA section, triggering the envelope
causes not only the new, played note to be heard when triggered, but all still held notes as
well. The envelope will go through again and all voices will sound again accordingly.
PARAPHONIC 2 (GREEN): In this mode, the envelope will only be re-triggered once all
notes have been released. If you add or release a note while holding, the chord changes
accordingly, but the envelopes remain neutral. This mode works well with high sustain
levels.
TIP: The paraphonic mode works only if you play the DELTA CEP A via MIDI. Polyphony
cannot be transmitted via a single control voltage.
