Saving money on the plugins?
This definitely. Getting the full bundle of fabfilter plugins for mac is quite expensive (and it and izotope are more than I want to spend on the mastering side of things right now based on how much I do it and everything).
That being said, the thing I most would use is Pro-Q 3, and the mac plugin for that is not really all that much more than the bundle.
Saving processing power on the mac?
Not really. Right now, I’m thinking about this as more of the mastering process, and I haven’t had any sort of issues with that level of stuff going on in my computer (sometimes if I have a lot of ableton devices when mixing, I’ll get clicks and pops…but I feel like multi-channel audio between the two sounds complicated and none of the solutions I’ve seen have been talked about as “rock-solid” and all seem a little fiddly to begin with.
Other things, I’m interested in are incorporating the iPad more in music making (and this seems like it could be an interesting step). My boyfriend and I got this fancy 12.9" iPad pro (which he gets a lot of use out of because he is an avid comic reader), but I haven’t really found a cool way to incorporate yet.
It also would be kinda cool to control things with the iPad’s giant touch screen as opposed to the trackpad I use.
That being said, based on the research I did it seems like this is potentially a cool workflow in a couple years that might not have any incredibly easy and robust ways at the current moment.
