I have used the TAL U-NO-62 synth for the bass here. The unit is in square wave mode with the chorus and noise switched off so take care with the VCF settings as they are very powerful on this synth.
Don’t be put off by the slider/fader-based interface, I find them more visually accurate than rotary controllers – you can really see where they are set, especially when shaping an envelope.
The Ableton Compressor is employed next for boosting duties here and for bringing the sound nearer to the listener. Again used to liven up the U-NO quite a bit, the compressor brings out all of the frequencies – the PSP then warms all of these elements combined.
This has been placed after the compressor so it’s processing a consistent signal and if you don’t have one at hand find something similar in your plug-in collection as mentioned above.
