"The great advantage of Roland Cloud, especially in the rough demo or sketch stage, was to have all the classic synths at your disposal. The ability to initially have multiple instances of the same synthesizer running together (something that would be difficult, and very expensive) is one of the wonderful features of the cloud. ‍ Once a track was created and approved, I could easily start printing or rendering the audio and in some cases double the sounds with my vintage hardware. ‍ This was especially true of the D-50 as I have the Roland Cloud version, the new Boutique 05, and my original D-550. The latter has some of my own sounds I created many years ago, but instantly evoke the sound of the ’80s. This was very important to the overall tone and vibe of Hyperbrawl.

I also loved mixing, say, the JUNO sounds with the JUPITER sounds. I also used the JUPITER arpeggiator on many of the parts as this added an extra melody or rhythm and is very different from the often more-complicated DAW versions."

Johan Berlin uses the Roland Boutique D-05 as part of his musical setup. As detailed in the Gig Performer Community, Johan shared that after releasing an album and being asked to play live, he purchased a used D-05 Boutique to complement his reliance on D50 sounds, stating, "I saw a small D-05 Boutique that I purchased used and thought that now at least I have two!" This supports his need for authentic 1988/89 sound replication during live performances.
