Digital inks done on iPad pro using astropad.
Manga studio on my mac, used via ipad pro and astropad. Yes, there was some slight lag/latency, but nothing that prevented me using the setup. I understand astropad has an update in the works that will hit before the end of the year, and I'm hoping it reduces the latency even further.
Which software on Astropad? Any latency compared to native iPad apps?
