Melbourne Instruments Delia Motorised Morphing Polyphonic Synthesiser

Classic style futuristic control

Delia is a bi-timbral polysynth inspired by the motorised control panel and voice architecture of the original Melbourne InstrumentsNina. Delia introduces a 49-key velocity and aftertouch sensitive keyboard, new multi-mode analog filters, high pass and low pass resonance control, 3-stage overdrive, and even more modulation possibilities. Paired with Rotary Recall technology, Delia opens the door to the sounds and direction of tomorrow.

Analog soul with a computerised 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 Delias unique 12 note mode, using 12 complete oscillator banks into the 6 filters, limiting note stealing without compromising the sound, and fully unleashing Delias bi-timbral operation.

Discrete multi-mode filters

Delias 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 24dB 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.

Total recall. Its not a dream!

At first glance Delia has fewer knobs than its predecessor Nina, but by no means does this limit control. Using our Rotary Recall system, Delia satisfies the demand for knob per function without an overwhelming number of knobs and menus, allowing players to move effortlessly between four oscillators, three LFOs, multi-mode filters, envelope generators and effects, providing the confidence to push the boundaries of performance and sound design.

Morph every parameter, then mod it

Delias 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.

Step into an infinite matrix of sound

The motorised journey does not end at Recall and Morph; Delias 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 4-Quadrant Analog VCAs, 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 Ninas discrete circuitry but add cross-modulation, and Delias 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 with the ability to save more than 16,000 presets inspiration and artistry will never be limited by available memory or slots. Delias high definition LCD also provides useful Waveform and Envelope visualizers, as well as instant feedback and display for almost every function as you interact with the control panel.
