Bad Bad Bass is also available as part of our Bad Bad Bundle, for an even keener price!

Taylor square traceWhen we were recording the valve oscillators for Tubes & Wires, we stumbled on simply the baddest-assed square wave we’d ever met. You can see it on the left. It came from a battered old Taylor signal generator and it’s the product of some very unhappy valves. It’s just crying out to be turned into angry, dirty, psychotic basslines, so we’ve given it its freedom and stuck it into Bad Bad Bass.

As well as the main square wave oscillator, there’s a sub oscillator you can blend in, running an octave below. This is also a valve waveform – in this case, a gritty and overloaded sine wave. It adds the gut punch to complement the main oscillator’s raucous roar.

You get full filter control for squelchy resonance and precision control of the mid / high content of the wave, plus some truly badly-behaved effects strapped across the output: tube saturation, tube drive distortion, a full-on limiter to tie everything together and add a big whack of grunt to the sound, and “oscillator drift” if you want your bass sound even more analogue.

Poly and Mono modes are available, with portamento / glide control for some slidey madness. The whole thing is bad… very bad. But you know that’s good.

Bad Bad Bass: a danger to itself and others.

(All our Kontakt instruments require a full copy of Native Instruments Kontakt v4.2.3 or higher (including all versions of Kontakt 5). Kontakt Player is not supported: instruments will load, but will time out after 15 minutes. See the FAQ for further information.)

\\\”Over the last two issues, we\\\’ve looked at two collections of instruments from new manufacturer Rhythmic Robot. This month we\\\’re going to explore RR\\\’s Laboratory. For a bit more explanation of what\\\’s behind these 24‑bit mono Kontakt instruments (which require the full version of Kontakt, rather than just the player), go to the first of our Rhythmic Robot reviews (/sos/may12/articles/beat_room.htm).

The Laboratory is where the Professor and his assistant Mongo construct new instruments out of whatever spare parts happen to be lying around. For example, they made a polyphonic synth from vintage Stylophones. Stylosynth has three oscillators and, although it doesn\\\’t sport a mass of controls, its samples have a warm and pleasant tonality. The synth\\\’s three oscillators are Vintage, Modern and Stacked. Modern is rather bright and slightly distorted, Stacked is a pile of old Stylophones in some warped version of unison, and the Vintage setting is mellow and generally the most pleasant. You are free to mix them all together in any combination and this layering generates some reasonably lush synth patches. Stylosynth has a resonant filter with velocity control, plus two envelopes and an LFO that modulates the filter. There\\\’s a chorus that doesn\\\’t quite replicate Stylophone vibrato, but I doubt this will be an issue for anyone — except maybe Rolf Harris.

Although Stylosynth is capable of blips and pads, it\\\’s not in the same league as Tubes and Wires, or TW1. This is the most expensive of the collection (still less than £20) and is based on samples coaxed from venerable signal generators. TW1\\\’s three oscillators are named after the devices that spawned their waveforms: the Advance H1, the Taylor, and the charmingly named Goodwill Function Generator. Images of each wave are shown on the rear-panel oscilloscope, and it\\\’s these that give the TW1 its wayward but distinctive character. After the oscillators, the architecture is simple enough. There\\\’s a dual-envelope structure with a resonant low‑ or high‑pass filter and extra buzz supplied by \\\”rail voltage”. This simulates overheating the circuitry, Louis and Bebe Barron would have been proud! Turn to the rear panel for a basic chorus and phaser.

Last up are two similar synths, the Bad Bad Bass and Bad Bad Lead, also full of valve oscillator samples. The main differences between the two synths are the source waveforms — low and aggressive or high and snarly — and there\\\’s a degree of overlap if you already have the TW1. Their primary oscillators are backed up by an additional, filthy, sine wave, and from then on there\\\’s a filter section comparable to Stylosynth\\\’s and optional poly or mono operation. In the shape of Drift, Drive, Distortion and Compression, you also get Rhythmic Robot\\\’s familiar tools for gaining attention.

This little collection scores highly for its raw valve tones and for its simplicity, an attribute often overlooked when throwing everything but the kitchen sink into sample libraries. It\\\’s true that, with patience, you could probably find a selection of signal generators in junk shops and at car boots, then painstakingly sample them to create your own unique instruments. Alternatively, these are priced so that you don\\\’t have to!\\\” – Sound on Sound magazine

    Bad Bad Bass & Bad Bad Lead
    Don’t Do It! Professor & Mongo, Don’t retire Bad Bad Bass & Bad Bad Lead forever! I saw your recent notice that they are going away but are on sale for a Ridiculous Price (for which I am very grateful, Thank You). So what did I have to lose? I grabbed both of them and loaded them up together to layer their sounds. The BBB & BBL GUIs are very similar, each with a Main Oscillator Voice and a second mixable Sine Voice. I turned up all the voices to full then bumped up the Drift, Drive & Distortion controls and played around with the Filters…. Whoa! The net effect was a Big Fat Screaming Four Voice Synth! The price for both instruments together is much less than that of a cup of coffee or tea! The beverage will be gone in five minutes, but you can keep these beasts forever! They are not only Bad Bad, They Are Bad-Ass!….

      Good news for lovers of the Bad Bads… we listened, and we’re not retiring them after all. They’re being bunged in Mongo’s Cupboard with their prices dropped to £3, and there they’ll stay. There was just too much love for these ugly little guys to put them out to pasture 😀

    This is so nasty, I love it. It can can uses for basses or leads or even pads… but with some ummmph! Don’t expect smooth.. BBB is all about rich, gritty, tone. This is also great for using to layer with other cheesy synths that don’t have any power (if you want it). Don’t be fooled by the price, you get A LOT of boom for the buck.

    The module is amazing.
    Nicely EQ’d

    Huge sound and powerful bass sound. This vst is one of my favorite since I like its strong oscilator which is like analog synths.
