Obviously a small sample size, but the people I know doing music as a living aren’t using NAM on a regular basis. I have yet to see it pop up in any of the production classes or mix walk-throughs.
Apologies for butting in here, but, coming from a perspective of reading and answering emails, or approving and supporting user posts, or chatting with various developers whose products support or build upon NAM, or with producers, mix engineers, or artists around the world that do use NAM in some form (note: there are now countless many ways to leverage NAM in a workflow) - it's pretty evident to me it's as popular choice as any really.
Love to know what records.
Again, apologies for butting in here - I'm not the target of this question...
But, that's not information people normally just throw about willy nilly unless they want to go through a mix rundown themselves, but I've seen a lot of finished music coming out in the last few years that I have been told directly has had some combination of NAM and other tech being used to great effect.
I like all sorts of technology, including NAM (of course) - and one of the great things in my opinion about NAM is that it relies on people still buying real amps, pedals, and outboard gear, and helps bring those products into the digital workflow of the modern era.
eg. I can now play through captures of my own gear, or other peoples, via a computer, a hardware pedal, or whatever.... and really fine tune my workflow. I don't need proprietary bespoke solutions such as a QC or a Kemper, which only works in one product.
We are living in a world now that is awesome for not only accurate reproduction of a great tone, but also one of flexibility - not only in workflow, but also in terms of fitting to any budget.
