Tighter Bass lines
At lot of third party synthesizers have the ability to have their oscillators set to "re-trigger." In a real analog synthesizer when you press a key on it's keyboard, the oscillator is triggered at random positions along the waveform. Sometimes it's at the top of the cycle, sometimes it's at the bottom. You end up with a varied, more unpredictable sound. In modern dance music where the bass needs to be tight and hit the same way every time, re-starting the oscillator at the exact same position is vital. Many people are surprised to know that the ES2 synthesizer has re-trigger built in...it's just not called re-trigger, it's called "OSC Start."
The soft position restarts the waveform/oscillators at the zero crossing point, where as the hard position restarts at the highest point of the waveform. Try changing your bass or lead sounds to to either soft or hard and hear the difference. You'll go from a relatively sloppy sound to total tightness.
