Realtime Support For Renoise

This scripts prompts you to enter your username and then it uses it inside the script to give realtime priority to that user

  read -p "Enter username: " USERNAME && echo -e "$USERNAME - rtprio 99\n$USERNAME - nice -10" | sudo tee -a /etc/security/limits.conf

when you run renoise you need to run it as sudo

so you no longer need to sudo open renoise:

  sudo -s

  chown root:root `which renoise`

  chmod 4755 `which renoise`
