“if Wacom provides a suitable App for iPadOS, an associated driver can be installed.”
For security reasons, I would expect Apple wants to review the driver code, if they even allow apps to install hardware drivers, which I doubt.
Not Roland, not Yamaha, not any audio interface maker installs an iPad driver.
I lose a lot of functionality with hardware on an iPad because it’s limited by USB compliance.
For example, DSP chips in audio interfaces are only available to a Mac or PC user.
Don’t get me wrong. I love my iPad, but let’s be honest about the limitations that keep iPads from achieving Steve Jobs original vision of the iPad being a device for everyone and the Mac becoming a device for niche markets and high computing power tasks, such as science.
Of course, that line is blurring too, with Apple’s powerful SoC now in iPads. For a lot of us, Steve Jobs iPad vision, which he had before the iPhone, is a perfect day-to-day computing solution.
