FWIW, I'd considered the issues I had earlier resolved based on my further findings since I would have used the VST3 version of the plugin by default anyway had I not accidentally used VST2 the first time and the project crash on opening seemed to be an issue with an old version of RealGuitar that just happened to be provoked by Neutron's being in there. I'd supplied follow-up notes to iZotope, not necessarily expecting to hear back after that since the issues there no longer affected me, but this morning I did get a response.
The start of the response bothered me a bit: "Thanks for contacting us, and I’m sorry for any trouble you’re experiencing! Please note, Neutron is not tested for compatibility with SONAR and may not function correctly in that environment." I guess the first line is just a generic customer service thing, but my problem had been resolved, so I was no longer "experiencing" it. The second line is the one that bothered me, though -- they don't test Neutron for compatibility with the most popular Windows DAW out there???!!!
The response continued: "We are actively tracking issues with this host application so your feedback is valuable – I will certainly forward this information along to our development team!" So at least they're tracking the issues, even if they don't test with it. :) It went on to refer to a URL (
https://www.izotope.com/en/products/mix/neutron/specs.html) with a list of compatible host applications, which SONAR was not listed in as of my check just now (the ones that were included Logic Pro X, Ableton Live 9, Pro Tools 10, 11 & 12, Cubase Pro 8, REAPER 5, FL Studio 12, Studio One 3, Nuendo 7 -- pretty much every major DAW, and a few less major ones, *except* SONAR!), then it went on to suggest I reinstall Neutron and use all default installation parameters (I probably did the defaults anyway, except possibly for the 64-bit VST2 plugin path if they didn't automatically append iZotope to the name of the default 64-bit VST directory, since I do sub-organize my plugins by vendor since I have upwards of 600 plugins). Needless to say, I'm not planning to reinstall the software since it is working for my needs.
In addition to mentioning my considering the issue to be resolved for my purposes and my installation notes, I included the following in my response to their message: "I’m very surprised to hear, though, that you did not test for compatibility with the most popular of Windows DAWs. I’ve been a longtime SONAR user (since version 1 and also its predecessor, Cakewalk Pro Audio 9, before that), and have never really had significant problems with iZotope products in that environment (and I’ve also been using iZotope products since at least Ozone 3, and possibly even the original version of Ozone – definitely the first versions of Trash and Vinyl). But, given the popularity of SONAR for Windows DAW users, you’d think that would be a high priority test environment."
As a quick update on my own use of Neutron, after writing my previous post, I went on to finish updating the instrument plugins on my project, then used Neutron on all tracks plus the mix bus -- on most tracks, Neutron, PSP VintageWarmer (for tape emulation) and the Pro Channel Console Emulator were the only plugins -- with Track Assistant being used to determine processing in all cases, including the vocal, -- no tweaks beyond that. Then I just used an Ozone 7 Advanced preset for a mastering stage and tweaked gain structure as needed to get to where the dynamic range to where I typically put things. There were also some aux buses for delay and reverbs, but those did not use Neutron. I have to say I was very pleased with the mix, especially considering how quickly I was able to get to it (i.e. without the normal messing around with different plugins and plugin settings and going back and forth). I've still got more tracking to do on the project, and I don't know that I'll necessarily keep the mix as Neutron-centric as this quick rough mix -- for example, I may want to flavor things up more with some of my normal PSP Audioware processors. But I also wouldn't have any qualms about putting the Neutron-only version out there if pressed to get something out quickly.
