The FB-3300 is a software instrument for Microsoft Windows (VST) and Apple macOS (VST/AU) simulating the KORG PS-3300 Polyphonic Synthesizer from 1977. It is written in native C++ code for high performance and low CPU consumption.
Main features are:
    Close emulation of behavior and all controls of the original hardware
    Three independent polyphonic synthesizer blocks
    Band-limited oscillators, classic two-pole lowpass filters
    Resonators section plus two Modulation Generators per bank
    Additional Sample & Hold and paraphonic Envelope Generator
    Semi-modular
    Micro-tuning option
    Additional tweaks
    MIDI Learn – all parameters can be controlled by MIDI CC
    Plug-in supports Windows and macOS (32 bit and 64 bit)

TAL-Elek7ro is a virtual analog synth with some special features like oscillator hardsync and frequncy modulation. Including improved alias free oscillators, new developed fast envelopes and lfo's with a wide range from 0.1Hz up to 400 Hz. A free routable envelope with attack and decay is available too. This synth is useful for a wide range of sounds from percusion to deep bass sounds.
Some features:
    2 oscillators with hardsync, PW and FM (saw, pulse, triangle, sine).
    1 sub oscillator (saw, rectangle).
    1 noise oscillator.
    18dB or 12dB non linear analog modelled low pass resonance filter.
    Mono mode, including portamento.
    Poly mode, up to 6 voices (not cpu optimized for poly mode).
    2 free routable Lfo's (0.1Hz - 400Hz, sine, triangle, saw, rectangle, s&h, noise).
    Filter and amplifier ADSR-envelope.
    Free routable AD-envelope.
    Mod-wheel and Pitch-Wheel support.
    Midi Learn for all pots.
    Velocity to filter contour intensity.
    Panic button.

Based on the most popular analog monosynth of all time!
This amazing softsynth sounds very close to the original Minimoog, yet has tons of additional features not present on the original Mini (as well as the Minimoog Voyager!)...
