Cobalt by Leslie Sanford is a nice free VSTi hybrid synth inspired by many of the digital synthesizers from the 1980s…
Though Cobalt is a purely digital synthesizer, its overall architecture is very much like those early hybrid synthesizers that combined earlier analog technology with newer digital technology.
It features a wide selection of waveforms, most of which were resynthesized from actual hybrid synthesizers, while providing traditional subtractive synthesis capabilities for sculpting its sound.
What i like:
32/64 Bit Operation, the sound banks and the low CPU usage.
