HG Fortune The Dreammachine 3 is a combination of a sophisticated algorithmic sequencer, a sample-based synthesizer with an extensive modulation section (several different types of LFOs, step sequence mod, XY mod) and a huge sample library.
The Dreammachine 3 allows you to produce complete ambient tracks, music beds, moods and accompaniments on its own. Musical contexts (progression) are created using the algorithmic sequencer, different samples per section and one-shot atmosphere and spoken interjections give the tracks structure and diversity, the complex modulation system makes for ever-changing sounds that successfully mask their sample-based origin and vary over time.

For further interaction there's a possibility to play parts via MIDI instead of the built-in sequencer.

The accompanying documentation PDF is very detailed and clearly explains the features of this instrument.

The Dreammachine comes with lots of carefully selected samples and presets that you can just load, let play and enjoy. As there are lots of possibilities, the presets are a good starting point for creating your own "tracks".

I consider The Dreammachine a very good plug-in and fully recommend it.
