Those I knew about. I try to stay away from the keyboard though, because I have arthritis in my shoulders. Doesn't affect my accordion playing, but it somewhat hurts to raise my arms up.
I hear ya Wally. I have similar issues myself.
I bought a used Mackie Control MCU off Craigslist for 175.00 USA bucks about 2 years ago and it has been possibly the best investment I have ever made, as far as a studio hardware upgrade goes.
It has 8 buttons that can be assigned to do almost anything within sonar, along with a button for every View.
Motorized faders, pan knobs, exc.
The thing I like most about it is Sonar has made upgrades to MCU and Alexys got a Mackie Control add on that he designed so communication between Sonar and Mackie controller is very stable and tight along with deep button assignment features. I also have 2 footswitches plugged in to the back of it for Punch recording and cycle dock tabs. but even those can be assigned to almost anything.
A hardware/control surface is the thing that really helped me most. because of fatigue and soreness. along with fact that once upon a time.. we came from the old school, where we only had buttons and knobs.
So it makes me feel more comfortable in that sense.
