Melbourne Instruments DELIA Hybrid Polyphonic Keyboard Synthesizer

The Melbourne Instrument DELIA retains the vital sound of overdriveable analog ladder filters, while using a digital front end to run modeled VCOs, wavetables, high pass filters and more. The powerful combination of analog plus digital is harnessed by Delia’s unique 12 note mode, using 12 complete oscillator banks into the 6 filters, limiting note stealing without compromising the sound, and fully unleashing Delia’s bi-timbral operation.

MULTI-MODE FILTER

Delia’s High Pass and Low Pass cut-off frequencies are separately controlled with two knobs, so overall operation can be High Pass, Low Pass or Bandpass. The assignable HP and LP resonance control offers flexibility to shape new sounds such as vocal-style formants. Delia’s ‘LINK’ function locks the distance between the High Pass and Low Pass knobs, setting a constant width Bandpass for manual control, and sweeps using the VCF envelope or other Mod Matrix controls. Adjust either filter in Link mode and the other filter will follow.

DELIA’s filters have an analog and a digital section per voice. This is combined with an analog variable overdrive circuit that can push the filter from normal operation to complete distorted collapse, adding richness, aggression and body to your sound. Delia’s High Pass Filter is a digital transistor-level mathematical model of a 24 dB ladder filter, based on the gold-standard Ebers-Moll transistor equations. This gives an almost perfect match to the response of the analog circuit.

MORPH EVERY PARAMETER, THEN MOD IT

DELIA’s A/B Morph function lets you explore and sweep through timbres like no other. The A/B Morph sound is an actively calculated change in parameters between the A and B patches including the entire modulation matrix. This provides the ability to instantly create a new preset based on the Morph position that is neither the A or B patch, but instead a totally new sound. Morph is also a ‘MOD destination’, giving you even more creative control via Aftertouch, Mod Wheel and Expression.

TOTAL RECALL

The motorized journey doesn’t end at Patch Recall and Morph. Delia’s ‘MOD MODE’ automates the Modulation Matrix setup. As you move between the 20 MOD sources, every knob changes position to display the active modulation amount. There’s no need to tweak the panel every time you switch sources or destinations, no matter how many modulations or slots are active. You can make your ideas a reality in a matter of seconds, literally shaping a sound as fast as you can think it. INIT > MOD > LFO TO WIDTH > PITCH TO CUTOFF > AFTERTOUCH TO MORPH > MODWHEEL TO EFFECTS > MORE RESONANCE ... SNAP! Delia gives you a sound design workflow that truly flows, combining the flexibility of a soft synth with the tactile experience of a hardware synth.

PHRASE LOOPING AND SEQUENCING

DELIA’s built in Sequencer offers two modes of operation. In Step Sequencer mode, DELIA allows bi-timbral operation up to 16 steps with control of note-values, step count, hold and MIDI assignment. DELIA’s Phrase Looper can loop and layer up to 2000 notes, with no additional time or overdub limits. Just like in Step Mode, bi-timbral operation allows you to control two layers independently, and with DELIA’s A/B Morph, you have four timbres at your fingertips.

BUILDING ON INNOVATION

DELIA inherits many of the acclaimed features of NINA, including 4-Quadrant Analog VCAs, Patch Morphing, Digital Effects and Digital Wavetable Oscillator. Adding to these features are Sequencer Phrase Looping and Overdubbing and Effects Macro control. Under the hood Delia is a beast! Virtual Analog Oscillators model Nina’s discrete circuitry but add cross-modulation, and Delia’s 20 MOD sources and 40+ MOD destinations with unlimited slots gives sound designers an almost endless spectrum of sounds.
