The Nabla is a software instrument for Microsoft Windows (VST2/VST3/CLAP) and Apple macOS (VST2/VST3/AU/CLAP) simulating the KORG Delta DL-50 Strings Synthesizer from 1979. Is is written in native C++ code for high performance and low CPU consumption. The main features are:

• Paraphonic Synthesizer and Strings sections
• Up to 64 voices polyphony
• Synthesizer section:
  • Four band-limited frequency divider-driven signal generators
  • Additional noise generator
  • 4-pole zero-delay feedback bandpass/lowpass filter
• Strings section:
  • Two band-limited frequency divider-driven signal generators
  • 2-band equalizer
  • Ensemble effect
• Flexible pitch/filter modulation by LFO or noise
• Tweaks (not to be found in the original Delta):
  • "GOD Mode" to provide true polyphony
  • Panning for Synthesizer/Strings sections
  • Built-in phaser and delay effects
• Double precision audio processing
• All parameters can be controlled by MIDI controllers
• Plug-in supports Windows and macOS (32 bit and 64 bit)
