Diva offers a rich synthesis experience by combining oscillators, filters, and envelopes modeled after legendary monophonic and polyphonic synthesizers from the past. Its architecture allows users to mix and match these components, delivering a range of classic analog sounds within a modern software environment. The emphasis on authentic circuit emulation sets Diva apart, recreating the sonic characteristics of vintage hardware with remarkable accuracy.

The standout feature of Diva is its use of real-time industrial circuit emulation techniques, which enable a level of sound authenticity rarely found in software synthesizers. This approach, inspired by professional circuit simulation tools, ensures that components such as zero-delay-feedback filters behave exactly like their analog counterparts, especially when driven hard. While this results in a higher CPU demand, it provides unparalleled warmth and detail in the resulting tones.

Diva includes a variety of filter types, including transistor ladder, Sallen-Key, OTA ladder, and state-variable designs, each offering distinct tonal qualities easily accessible through a visually appealing interface. Since version 1.3, the synth has been enhanced with a Digital Oscillator, the classic 'Uhbie' filter, and a vintage-style arpeggiator, further expanding its sound design possibilities and inspiring creativity across musical genres.
