There is differences between them that makes it worthwhile to inspect what is your preference.
Not going to list them as both apps have demos and would advice anyone to check it out for themselves plus the workflow is fairly different as well.
Anyway with this upgrade maybe the biggest difference is that n-Track Studio have started using a subscription fee instead. I am normally against it as I prefer to own the software but in this case it is kind of interesting as it probably not often that most people do serious recordings on their mobile devices as it is much more convenient to record on computer. But maybe the computer gets broken, a need to record your guitar playing cousin in hicksville or vacation etc it can be nice to just pay for a month?
It is not too much, one euro for a basic subscription and two for a pro one.
The main difference is 32/64 bit export for the pro version instead of 16/24 bit for the basic.
To be honest do not think that there is a high amount of people that can hear the difference between 24 bit and 32/64 bit.
So that means one euro a month instead of twenty or so which the older version cost and what more or less Audio Evolution cost with the goodies activated.
So after doing the math and unless you need the higher bit rate plus Multichannel USB class-compliant audio interface and only use it for a month or two it becomes pretty cheap.
Ahh yes n-Track Studio also comes with the exciting song collaborating app SongTree incorporated. That could of course become addictive and costly in the end... after five years or so...
The owners of the older Pro version gets four months for free or just do not upgrade to avoid the subscription plan.
