Layering Other Waveforms

The sine and triangle wave produces that low thumping bass tone we electronic composers love (e.g. sub bass, 808 boom, DnB drone). These waveforms have few or no harmonics, so they are felt more than they are heard. If using a synth (or even a sampler), try layering these waveforms with a waveform rich in harmonics, such as a square or saw wave. After layering, use the synth's or sampler's low pass filter cutoff to trim away some of the higher harmonics from this new bass patch. Try adding a sine wave an octave down from from your other chosen wave forms and apply a positive pitch setting just enough so you hear a slight thud ,keep your sinewave low so it doesn’t dominate your overall sound , now just stand back and watch those woofers move . mainly applies to analogue and analogue modeling.

Real Bass
Yet another layering approach is to layer your deep synth bass patch with a real bass. This can either be an actual recorded bass guitar, or a patch in your sample library that sounds like a real bass. Since real basses are usually higher in frequency and more punchy than synth basses, your the deep bass will be heard and felt more on systems with good bass response, but the real bass layered over the top will be heard more for those with less fortunate systems.
