If you’re reading and following this blog you ought to be interested in bass. And because of that, I’m giving you two – not so obvious – techniques on how to accentuate your synth bass sound.
Using the high-pass filter to boost bass
Okay, so you know what a high-pass filter is right, and that its cutoff frequency is the point at where the filter limits the low frequencies and lets the high pass.
You also know about resonance, and that it’s generally used to give a brighter/thinner sound. (And when the resonant setting is cranked to max, some filters go into self-oscillation and which make them scream.) But when high-pass resonance is added, the note and overtones near the cutoff are boosted – in other words, this is lifting the bass.
Just use keyboard tracking to make the resonant peak follow the pitch of the note and cutoff to follow the keyboard. The fundamental note will now be boosted while the surrounding spectrum is unaffected.
Use two filters in series if possible, set the other to low-pass filter and reduce harsh elements of the sound.
Get bigger bass by focusing on midrange
To get louder bass it’s not always necessary to pump up the level or to boost the lower frequencies, no you could just draw more attention to the bass element. Add midrange to it – it’s almost a mindtrick, and it shouldn’t make the bass any muddier.
So saturate the overtones of the bass or sculpt the thud of the kick drum. This is also valuable when there are several sounds competing for room in the low end.
