Hi JR,
I am in a similar boat as you but I think I am a few months further down the road. I tried moving from PT about 8 months ago but like you found the stress too much as I learnt more about Reaper whilst delivering projects. Faders and tactile controls are important to me and back then
Geoff's CSI Project had some ways to come, so I would not only be losing the familiarity of Pro Tools, but also my control surface (S3 and transport).
With the challenges of COVID-19, I decided to resurrect my interest in moving to Reaper, and was so pleased to find the the CSI project had made leaps and bounds. After a week of total absorption into the Reaper world, I think I am almost committed to migrating. Last up is trying out a full 2-3hr 180ch mix with 4K video proxies. But, initial tests suggests this is completely fine.
I
LOVE the efficiency of Reaper, it seems to offload all DSP through a wormhole to another dimension, as the app often shows its using less resources that Apple Notes.app. insane. And how the hell has Cockos made all this in a 20mb download? Nuts!. I
LOVE the almost complete accessibility of actions and scripting. If you think of a workflow, you can probably make it! And, you can get into coding your own plugins. I
am ambivalent about the GUI.... I know this is personal, but its important to me. My resistance to spending time modding a theme to my needs is reducing, and I know it will pay dividends.
During this week of deep diving into Reaper, Avid released the long awaited update to Pro Tools 20.3, which of course finally adds folders to Pro Tools. Downloading and installing this update I felt sad as I felt potentially resigned to returning to the old familiar workflow, and to forget about the new freedoms found in Reaper. Yes, PT is familiar and the interface makes me feel less stressed, but opening it up and trying out the new features, I was struck by a sense of constraint.
During my week of testing with the 180ch session, Reaper never crashed, stopped, complained or even raised a sweat at this project. However, opening up and playing this session in PT 20.3 , it wasn't long before the session stopped and complained of the occasional CPU, or disk issues. Not a quantitive study of course, but just a day in the life of PT in my experience.
Thats a long rant sorry.
At the end of the day, I feel that we are part of a growing movement of folks who are looking for something different in our Tools. My view is that Reaper and its insane extensibility, coupled with the CSI Project, is an amazing production workflow option for those who are open to getting their hands dirty. I thinks its important we don't down-play the very steep learning and configuration curve, as this present a significant barrier to entry for a lot of folks.
Best of luck!
