Which device to pick for Gadget? Suggestions for performance and usability benchmarking
I am looking to buy an iOS device with Korg Gadget in mind as primary app. Which one to pick? How to pick?
Performance: Presumably Korg Gadget runs on any iOS device with 9.3 or newer. This means that it could run on an A5 (as in a 2012 iPad 2) to todays A12X. But how much is "enough" power? How to measure this?
Usability: with different resolutions, screen sizes and aspect ratios come different levels of usability. A 4" display is almost unusably small, but is 12.9" so much better than 10.5", 9.7", 7.9" or even 6.5" what is de cutoff point?
Others: does RAM size matter? Having a headphones port matters, but how much?
Ideally, I would never run into stuttering performance, be able to tweak buttons, edit the sequencer and play notes without feeling encumbered and be secure in the idea that I have the most optimal pick for my needs. Perhaps in this community we could build a song template that will let one test the real life performance of Gadget. I think it would be best to do this with the gadgets that are available in the "LE" version, so it can be tested on any device, even if the user does not have the full version of Gadget (also curious about the Mac and Switch versions). This song would use several different gadgets and one could keep duplicating the tracks until artefacts appear. This would need to be done with a predefined latency setting, but perhaps multiple settings could yield useful insights.
As for screen usability: 4" is too small, as is 4.7". But when is it big enough? How many strips can fit in the song view? Do the sequencer view and gadget view benefit from this aspect ratio?
I would appreciate any ideas. Meanwhile, I will build a pretty basic song to stresstest Gadget with.
