Delia Hybrid Polyphonic Keyboard Synthesizer

KeyboardHybridPolyphonic

Imagine a synth where the knobs actually move on their own, snapping back to life as you switch presets—it's like the instrument is alive, responding to your every twist. This motorized control panel sets it apart, making deep sound design feel effortless and immediate, especially when morphing between patches or layers.

At its core, it's a 6-voice bi-timbral hybrid polysynth with four digital oscillators per voice: two virtual analog VCOs, a high-res wavetable oscillator supporting custom WAV uploads up to 256 frames, and a noise/XOR/aux source. Sound flows through a digital highpass filter, an analog overdrive circuit for gritty drive, then a true analog lowpass ladder filter—both with independent cutoff and resonance knobs, plus a Link mode that locks them for precise bandpass or notch sweeps, selectable 12/24dB slopes, and multimode flexibility. Three variable waveshape LFOs, three envelopes (VCA, VCF, aux), and a massive 20x40 modulation matrix with unlimited slots let you route wild cross-modulation and morphing. Hands-on features include a 49-key velocity-sensitive keybed with polyphonic aftertouch, a 16-step sequencer, phrase looper for unlimited overdubs up to 2000 notes, dual effects (chorus, delay, reverb) with macro control, and over 400 presets, all on a high-res LCD. It's compact at 32 x 12.5 x 5.6 inches and 19.1 lbs, with stereo 1/4" outs, MIDI in, USB-C, and USB-A ports.

Players love how the dual filters unlock vocal formants and aggressive tones unattainable elsewhere, with the phrase looper shining for quick songwriting layers. The motorized faders and Nina-inspired architecture earn praise for workflow and monstrous analog warmth, though some wish the highpass was fully analog too—still, it's hailed as a streamlined evolution in hybrid polysynths.
