We featured New Sonic Arts in the past with our Granite review (our collaborator loved this intuitive granular texture generator!).
Some months ago the company released Freestyle, a smart-looking VST host with interesting features for live performers (macro controls & snapshots) and studio users (for sound-design adventures).
With Freestyle you can split, layer and combine your VST instruments and FX to explore vast new sound design possibilities. Freestyle integrates perfectly with your DAW, running as either a VST or AudioUnit plugin.
The product has already received relevant updates and you can support its roadmap buying a license for only $69 (50% OFF, until Jan 5).
To me, Freestyle looks like a better option than Apple’s Mainstage. Sure, it’s more expensive but its modular nature allows for more creative patching (and it loads VSTs!). If Mainstage doesn’t cut it and more complex/powerful products like Plogue Bidule look too intimidating, check out Freestyle.
