A waveform consisting of a number of slightly detuned sawtooth waves superimposed. This waveform is frequently used particularly for lead and bass sounds in the trance and hardcore genres. It produces a characteristic buzzing sound which is sharp in the treble, but not thin in the bass like a conventional sawtooth can be.
The supersaw was originally popularized by the Roland JP-8000 virtual analog synth in the 1990s. It saw a revival in the mid-2000s as many soft synths and more recent virtual analog synths included the ability to produce the waveform.
