Q: Does Sounds4Fun eat up a lot of CPU time?
A: That depends on what sounds you choose to associate to what events. If you choose to play random instruments sounds from Garageband on every key press (choosing Rock Kit, for example, will make you sound like Ginger Baker every time you type an email or something), can cause CPU spikes going up to 30% or so depending on how fast you type (keeping a key pressed to repeat can cause the CPU to reach as much at 70% or more on my Intel Macbook Pro). On idle, Sounds4Fun will consume about 0.40% due to its polling for certain events.
