How to make any bass - Example (Regular Fantasy - So Sweet Remix)

A quick and easy step by step guide to write any bassline in Ableton Live using a wavetable or any synth you may like.

This post was inspired by a fellow redditor. Thanks!

Step 1 - Add Reference Track

Working side by side with a reference track always helps. I have loaded the reference onto a new project in Ableton, this will allow me pause and listen to the sound I'm trying to replicate carefully.

Step 2 - Create your bass line

Add a wavetable into a new midi track.

Now, write the bass line using the piano roll to match your reference track. Knowing the BPM and root key of the reference song is helpful. In this particular example, the song was written at 130 BPM in the Key of DMaj. Note: Don't worry about sound design at this stage, all you want to get is the notes and timings right.

This is how it sounds.

Step 3 - Sound design

Here is the fun part. Go back to your reference and listen carefully to the sound you want to replicate. All you have to do is to thinker with the parameters in your wavetable to match your reference track. For this track, I to used two saw tooth waves.

The reference track has a plucky finish to it. We can accomplish this by modulating the frequency knob. I've adjusted the starting point of the filter at 45.6 Hz and modulated it (Filter 1 freq in the matrix) to follow the Amp parameter. In case you don't know, this will make the filter 'bounce' every time a midi note hits.

All this should sound something like this:

Step 4 - Final touches

I will make the final sound design adjustments by adding some effects and EQs. In this particular example I'm bringing up the low frequencies to make the bass line punchier (Drum Buss), cutting tome of the high frequencies (EQ8) and finally making the sound mono, in case I ever play this on a Club. Here is a screenshot of the device chain after the wavetable.
