i did use mouse a long time, this suddenly stopped when my right hand was starting to hurt that bad, that at the end of a mixing day, i couldn t even hold a cigarrette. soon it became that bad, that i could nt open the hand anymore, because it was "locked" into a fist. after long and busy sessions, this state could only be ended by medical injections to loosen the muscles and nerves.
therefore, i started to build a modular system with doepfer midi controllers (potis, faders, knobs) etc, and write all automations and stuff like that with those. this helped me a lot and since then i never had such problems with my hand again.
i try to use the mouse as less as possible. not because of any ideologic or any other reason, than health reasons. for me there is no point in doing what i love to do, when it hurts that bad and leads to such pain and renders you to a crippled person.
i write this for all the others to consider, that exessive mousing can really lead to really bad ass pain and health issues.
