MELBOURNE INSTRUMENTS DELIA Motorized Morphing Polyphonic Synthesizer

Analog Soul with a Computerized Brain

Using a combination of true analog filters and virtual analog modelling, DELIA retains the vital sound of massively overdrivable 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 bitimbral operation.

Discrete Multimode 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 for bandpass and notch operation. With 12 and 24 dB slopes and separate high-/low-pass resonance control, there is huge scope when shaping sounds, from the most delicate plucks and pads to the wildest overdriven bass and lead sounds imaginable. Delia is an inspiring creative companion and dependable instrument for musicians and composers, no matter what their level.

Analog + Digital Filters

• DELIA�s filters have an analog and a digital section per voice. The analog filter is the classic discrete transistor ladder filter offering a choice of 24 or 12 dB per octave operation. Prior to this filter is an analog variable overdrive circuit that can push the filter from normal operation to complete distorted collapse of the transistor ladder, adding richness, aggression and body to your sound. 
• The HP 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, including overdrive response, resonance, and natural filter frequency variations.
• The filter is multimode with 3 ways to configure. The high-pass and low-pass cutoff frequencies are separately controlled with 2 knobs, so the overall operation can be high pass, low pass or bandpass. The separate HP and LP resonance controls offer flexibility to shape the sound including vocal-style formants. Delia�s LINK function locks the distance between the Low Pass and High Pass knobs, setting a constant width bandpass for both manual control and sweeps using the VCF envelope or other Modulation Matrix controls.

Total Recall

The motorized journey does not end at Recall and Morph; Delia's MOD Mode automates the Modulation Matrix setup. As you move between the 20 modulation sources, every knob changes position to display its modulation amount. No need to tweak the panel every time you switch sources or destinations, no matter how many modulations or slots are active. Delia gives you a sound-design workflow that truly flows - combining the flexibility of a soft synth with the tactile experience of a classic hardware synth.

Morph and Mod Every Parameter

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.

Infinite Matrix of Sound

The motorized journey does not end at Recall and Morph. Just like Nina, Delia's MOD Mode automates the Modulation Matrix setup. As you move between the 20 modulation sources, every knob changes position to display its modulation amount. No need to tweak the panel every time you switch sources or destinations, no matter how many modulations or slots are active. Delia gives you a sound design workflow that truly flows�combining the flexibility of a soft synth with the tactile experience of a classic hardware synth.

Building on Innovation

• DELIA inherits many of the acclaimed features of Nina, including four-quadrant analog VCAs, morphing, digital effects, and a 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 crossmodulation, and Delia�s 20 modulation 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 the ability to save more than 16,000 presets inspiration and artistry will never be limited by available memory or slots

High Definition LCD

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

Control Panel Automation

• Instant preset recall: every knob moves to position
• Interactive morphing with parameter isolation
• Interactive Mod Matrix setup
• Instant layer recall: panel changes to active patch
• Multi LFO, envelope, and filter settings recall
• Effects level and macro parameter recall
• Instant INIT control-panel reset
