Support for Drawing Tablets?

No, none support them in a meaningful way, nor do they really support the Pen input mode in windows (for graphic tablets and pen tablets). I do run cubase and Energy XT from time to time on a Fujitsu pen tablet because it has a daylight screen and it does work with the Pen only input but with the exception of drawing curves it is not a great way to control a sequencer, superb for working with additive synth plugins though…

The only notation program that supported pen input was from Microsoft and it worked rather well but is no longer available and not near professional standard anyway, there is an freeware experimental effects VST out there somewhere that was expressively designed for pen usage and it is a hoot to use with a pen.
