The patches I hear in the Luftrum demos are very nice and have a very analog and vintage tone, a testimony to Diva's capabilities, but I can say with confidence that Omni can achieve the same kind of tone and color very well. Maybe not better than a beast like Diva, or the best of the dedicated emulations, but even in a fairly simple mix and arrangement like synthwave songs tend to have, it can fare very well.
A DSP-waveform, some pitch fine-modulation, The Warm 24db/UVI-filter, Chorus, drift if in Unison (although I prefer Harmonia) and the specialty of Omni, a sampled synth waveform/sound to give the sound an interesting timbre, a good reverb and the vintage vibe is very strong with this one.
