WhySynth is a DSSI softsynth plugin featuring subtractive, wavecycle, granular, FM, and waveshaping synthesis in a flexible-but-efficient non-modular design.

Features:

• 4 oscillators, 2 filters, 3 LFOs, and 5 envelope generators per voice.
• 6 oscillator modes: minBLEP, wavecycle, asynchronous granular, FM,
  waveshaper, and noise.

• 5 filter modes.
• flexible modulation and mixdown options.

New in v20070418

• Two new oscillator modes: phase distortion similar to that used
  in the Casio CZ series synths, and another FM mode.

• GUI enhancements.
• Improvements to the envelope generators, making them more
  responsive to realtime parameters changes.

• A few new patches.
• Some GCC 4 fixes.
