"Synth Explorer - Jupiter 6" by Loopmasters is a great trip into the history of electronic music. Well-programmed and mixed, and fully utilizing the capacity of the Jupiter 6, this sample pack is a solid idea. The only catch is that sound design has advanced so much in the past couple of decades that it is unclear what the use of a vintage sound pack is other than to explore history or create a vintage-sounding song.
Highly satisfying rage of classic Jupiter sounds. Loads of chords and stabs as well as the typical lush pads and strings. Well recorded - retaining the warms and character of the original instrument.
Still wish I could tweak some of the parameters on the real keyboard though!
