There are special stylus pens for capacitive touchscreens with a soft end, I would use one of those, I use it for my iPAD sometimes.

Ipad yes...

But touchscreen on a keyboard, no way, i dont have time to grab the pen everytime i need to make realtime changes. and my playing requires my 2 hands...

many people use stylus on the kronos because many of the items are so small, but just does not work for realtime changes... only for programming the thing before a performance...

The orthopods don't deal with this as it's a vascular problem often triggered by repetitive impact to a specific area. The orthopods primarily deal with joint disorders, which is quite different.

As for the diminished blood flow, yes, you could have it, but not to the point where you see color change in the extremities. I have it, and my hand and finger color is perfectly normal, however, the flow is diminished by about 40 percent in my left hand, and 60 percent in my right hand. In my case, I did a lot of dumb stuff when I was younger, like splitting my own firewood, pounding bricks into sand to make my own sidewalk and patio, stuff like that, which eventually takes a toll on extremities. Additionally, I punched those PC keyboard keys every day of the week, writing 1,500 to 5,000-word magazine and newspaper articles for fishing and boating magazines. I often felt an aching in my hands at night and soaked them in hot water to relieve the pain on a nightly basis as I grew older.

My wife also has it, but not quite as severe as mine. She acquired hers by constantly punching IBM cards when she was very young. In order to get a proper diagnosis, you need to consult with a vascular specialist - not an orthopod (orthopedic surgeon).

Good luck,
