RetroVibes ($7) contains samples captured from hardware and software, split across 48 instrument presets, from brasses to leads, keys to basses, percussion, guitars, etc.
All the presets were inspired by the 80s sound and are suitable for Pop and EDM styles, including SynthPop, Future Pop, Hip Hop, House, and subgenres alike. They are 100% royalty-free.
The GUI is straightforward simple with typical controls such as ADSR envelope, modulation, filter, reverb, etc.
RetroVibes Lite is a free version of the full instrument plugin, the only difference is that it features 16 presets instead of the 48 found in the bigger and commercial version. Apart from that, everything is fully functional and similar to RetroVibes.
Both plugins are available in VST/VST3 & AU 64-bit versions for Windows and macOS.
