The Master toolbar allows you to affect the speed of all your automations at once. The toolbar contains a scaling percentage that's applied to your oscillator frequencies. If the scaling percentage is 100 (the default), the automations are unaffected; at 200 they're double speed, and at 50 they're half speed. To display or hide the toolbar, use View/Master or Shift+M. To change the master speed, set the desired percentage, via either the slider or the edit box.
If the CPU is overloaded while you're developing a project, the actual frame rate may be less than the ideal, which means your automations may seem slower than they actually are. You might not discover this problem until you record the project and watch the output video. If this situation occurs, you can use master speed to slow down your automations proportionally, instead of editing them one by one.
