Are there any inexpensive art apps to use with the Art Overlay?

Krita’s pre-alpha might work better on Win8+.

In the end, my “cheap solution” was to buy a fast USB stick and install Ubuntu Studio 17.10 on it. Reboot to the USB stick and you have Krita with Morph support, as well as a bunch of quality music and video studio programs that should support other overlays. There’s no Linux version of the Sensel app yet, so you have to return to Windows to configure the unit.
