Three pro patchmaking techniques
> Technique 7. Draw custom wavetables
Let’s create a DIY bass patch from scratch with Serum’s editable oscillator modules
1 Click Osc A’s pencil icon to open up the waveform editor, then hit Add/Remove » Init All in the menu to initialise the wavetable. Draw a funky waveform using the tools on the left side. For extra precision, grid options are found at the bottom right.
2 The thumbnails under the editor show all the subtables inside your wavetable. Click the + to copy your subtable into the next slot. Now draw a fresh waveform in the new subtable – try using the noise tool to fill in in gritty upper harmonics.
3 Select your second subtable, click Morph » Morph - Crossfade. This produces a 256-frame wavetable, interpolated from what you drew. Exit the waveform editor, and click the oscillator wave for 3D display mode. Now modulate that wavetable position!
