OK, this thread just changed the direction towards the question: "SuperNATURAL Tones vs dedicated software" and "hardware vs software".
The Roland SuperNATURAL Acoustic Tones (apart from the unique SN virtual analog Synth engine) will never be able to compete with dedicated software solutions, like e.g. the mentioned "SampleModeling" software or e.g. "Arturia Brass", etc., concerning pure realism and imitation of real acoustic instruments during the production process in the studio.
But the SN Acoustic Tones doesn't have any load time and are immediately available on all 10 Jupiter-80 parts or all 16 Integra-7 parts.
The SN Acoustic Tones are very epressive sounds, which are a JOY to play ON A KEYBOARD as A KEYBOARD PLAYER. They have a certain quality in this regard, which is unmatched by any software solution I own, and I have plenty of the best currently available plugins to compare with.
As a synth player and in my "synth philosophy", those SN Acoustic Tones are just synth sounds to me, which of course associate to the original acoustic instruments, but have their own and unique sound character, which is sometimes quite far away from the real instrument they intend to simulate.
Especially the combination of those SN Acoustic Tones with the SN VA-Synth Tones are offering an incredibly rich and expressive synth sound, which is unique and just very inspiring to play.
The SN Brass and String sections are an exception, because they are very capable of delivering realistic sounds for a mix. But to get the last kick of realism, you will mix those SN Tones with dedicated software sounds. It just depends on the situation and what you need.
The SN Acoustic Piano Tone for example is just the best "digital piano" I've ever played. But dedicated piano software comes much closer to a real piano with all of its natural weaknesses, if you are looking for the perfect grand piano simulation during the production process in the studio. But I don't know of any software piano, which offers the rich expressiveness, playability and joy of the Roland SN piano Tone. It's like the perfect unreal piano, which couldn't exist in the real world.
But all SN Acoustic Tones are outstanding performance sounds, irrespective of their "realism"!
The SN Acoustic Tones are in my view finally more surreal than real, but I love their sound quality and unique expressivenes anyway, or better said: I love them exactly for this surreal or unreal sound character!
Finally: A good Laptop with top software is of course the better and much more powerful sound and production module/tool than the Integra-7. But the advantage of the I-7 over a Laptop is the immediate availability of a plethora of quality Roland sounds without any loading time, which in my view predestines the Integra-7 as a performance sound module or as a good completion to your current DAW setup. The Integra-7 finally offers almost the whole Roland sound palette from their whole synth history of over 40 years in a pristine sound quality...
