Motorized Morphing
Polyphonic Synthesizer

49 Key Velocity & Aftertouch Sensitive

DELIA is a bi-timbral polysynth inspired by the motorized control panel and voice architecture of the original Melbourne Instruments’ NINA.

Delia introduces a 49-key velocity and aftertouch sensitive keyboard, new multi-mode analog filters, high pass & low pass resonance control, 3-stage overdrive and endless modulation possibilities.

Analog soul with
a computerized brain

Using a combination of true analog filters and virtual analog modelling, DELIA retains the vital sound of massively overdriveable analog ladder filters, while using a digital front end to run modelled 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.

Delia’s Multi-mode Filter

  • Discrete Multi-mode Filters

    DELIA’s true analog Low Pass Filter is the heart and soul of the sound engine — warm, full and sweet or fearfully aggressive. It is complemented with a high-pass modelled ladder filter which can be linked with low-pass for bandpass and notch operation.

  • Analog LP + Digital HP

    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.

  • 'Link' for Bandpass Filter

    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.

  • Shaping your sound

    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. 

  • Digital High Pass Filter

    Delia’s High Pass Filter is a digital transistor-level mathematical model of a 24dB ladder filter, based on the gold-standard Ebers-Moll transistor equations. This gives an almost perfect match to the response of the analog circuit.

Total Recall.
It’s not a dream!

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.

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.

Phrase Looping & 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 & 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.

Craft ideas using simple keyboard splits, or lose yourself in evolving stacked layers and sweeping morphs across vastly different sounds.

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 the inclusion of Sequencer Phrase Looping and Overdubbing, and the ability to assign your favorite effects parameter to the 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. Two digital effects processors paired with classic effects presets and the option to run in series or parallel offers creative freedom. And with the ability to save more than 16,000 presets, inspiration and artistry will never be limited by available memory or slots.

Waveform, Wavetable and
Envelope Visualizers

Delia’s high definition LCD also provides useful Waveform and Wavetable visualizers, as well as instant feedback and display for almost every function as you interact with the control panel.
