Description
Nabla is Full Bucket Music’s emulation of the KORG Delta DL-50 string synthesizer from 1979. It combines a paraphonic synthesizer section with a strings section, reaching up to 64 voices and adding modern touches such as true polyphony, panning, phaser, delay, and MIDI control.
The synth side uses four divider-driven generators, noise, and a zero-delay-feedback filter, while the strings side adds two generators, a two-band EQ, ensemble, and LFO or noise modulation. Win32, Win64, and macOS VST plus AU builds are listed.
