Polysynth built from vintage valve signal generators


“Tubes & Wires is based on samples coaxed from venerable signal generators. These three oscillators give Tubes & Wires its wayward but distinctive character. Louis and Bebe Barron would have been proud!” – Sound on Sound magazinesos logo tiny

“This instrument is arguably one of the worst possible choices if you’re looking for a synthesiser with a clean and sterile sound” –Bedroom Producers Blog

Advance front panelTubes & Wires is a huge, rusting hulk of a synthesiser, smelling of Bakelite and hot valves, glowing and humming and breathing.

The heart of this synth lies in hundreds of careful hand-tuned samples of three classic vintage signal generators. We chose these bits of ageing scientific lab equipment specifically for their character and crusty goodness: there isn’t a clean trace among them. They’ve been used, and abused, and left in the dusty sheds of men with beards, until we rescued them and made them sing for us.

Their wonderful raw materials, sampled at 24-bit, are then run through three parallel sets of switchable filters, three parallel sets of amp envelope generators, and three parallel “Rail Voltage” controls to simulate running their circuitry too hot… resulting in tube saturation effects which you can control on a per-oscillator basis. The sounds are rich and unstable to begin with, but a touch of Rail Voltage really brings out their raucous edge!

Taylor front panelTwo separate LFOs route to pitch and amplitude for simultaneous individually-addressable tremolo and vibrato, while global stereo spread and oscillator drift controls allow you to fine-tune stereo width and analogue pitch instability. Round the back are Chorus and Phaser effects modules with control over depth and rate, to give your patches extra vintage warmth or a little stereo shimmer. We’ve also added a set of oscilloscope traces showing each individual wave type.

The whole synth can be switched from full poly to mono mode, with adjustable “glide” (portamento) – so you have everything from pads and strings, through resonant brass, to bass and mono lead lines, right where you want them: all with an unmistakeable, utterly unique, vintage glow.

It’s all about the oscillators…

Advance sine traceThe first oscillator of Tubes & Wires offers both sine and square waves from a rusting old Advance H-1 valve (tube) signal generator. This was by far the most erratic and beaten-up of our selection, and the Kontakt UI reflects this. The sine wave is full of crackles, intermittent noise and glitches from some bad internal connections and a faulty amplifier circuit. It also periodically distorts, flattening the wave slightly. This makes for a wonderfully characterful palette of sound – or you can high-pass filter it until just the crackles and glitches remain, and add these to taste to the other two oscillators to give them a similar kit-on-its-last-legs vibe. It’s quite simply the most un-sine-like sine wave we’ve ever heard. You can see a trace of it to the right.

Advance square wave traceThe Advance square wave setting was, basically, broken. It produced unusable shrieks and cyclical howls. But we found if we lodged the sine / square selection switch at just the right point, we could get a weird, hot, metallic tone from it. It was contaminated with a fair amount of mains overtones and has a very peculiar tonality – almost as if its being ring-modulated. (Who knows. Perhaps it is.) This is what we’ve captured as the Advance “square” wave: a kind of throbbing, warmly dissonant roar that conjures up sci-fi soundscapes and malfunctioning racks of laboratory equipment. Here it is on the left.

Taylor square traceThe second oscillator offers a choice of, again, sine and square waves, this time from a Taylor valve (tube) generator. This turned out to have a magical sound quality, as though it had been secretly practicing at being a synth all its laboratory life. Its square wave is a very aggressive, distorted, peaky waveform which is instantly at home being low-pass filtered in classic analogue synth fashion – you can see it to the right here. We found this was our go-to oscillator for a lot of classic patches (and indeed it’s also become the core of Bad Bad Bass).

Taylor sine traceThe sine wave, meanwhile, was being clipped quite badly by its output circuit – which was great! It gives it far more edge than a standard sine – perfect for reinforcing the fundamental frequency of a bass patch, for example. There’s some instability that increases as the wave goes up in pitch, too, so that by its higher ranges it’s starting to look more like a kind of weirded-out square wave.

Goodwill sawtooth traceThe third oscillator is taken from a transistor-based Goodwill function generator. We chose this because old valve signal generators generally only offer square and sine waves, and we felt a proper polysynth should have sawtooth and triangle too. Of course, we made sure to choose a Goodwill that was far from perfect. With the duty cycle control of its Ramp waveform turned all the way clockwise we found a good, buzzy sawtooth wave which nevertheless has a lot of slew and inaccuracy in its cycle: sort of a “rose-tinted” sawtooth sound!

Goodwill triangle traceTowards the middle of the Ramp generator’s duty cycle we get what’s trying to be a triangle wave, though it’s frankly a bit weird. It looks like it’s been welded together from two different triangle waves in some kind of backstreets chop-shop. But it sounds great. You can of course rough if up still further if you want to by using the oscillator’s “Voltage” control to deliberately overdrive it. (Remember, you have this control available individually for each oscillator – so you can layer up some really steamingly warm patches in no time!)

You can probably tell that we love Tubes & Wires to bits, and would witter on about it all day if we could. Our goal with it was to get the richest raw materials to start with, and then to complement them with really versatile controls so you can get the most from them. This is a synth that wears its vintage credentials on its sleeve: dusty, crusty, growling and screaming, it’s a world away from today’s squeaky-clean digital world.

Tubes & Wires: get blinded with science!

    If you’re ever wondering where the peachy overlap of science and art is, it’s right here.

    Rough and raw sounds are its heart and soul, and if they are yours, too, grab it.

  3. DON Chaffer (verified owner)

    Okay. This is one of my faves. Something about its controls, and the way it speaks in a track just makes a LOT of sense to me, and I regularly feel like I can get it to give me an atmospheric wash that doesn’t sound familiar, but accomplishes familiar duties, plays a familiar role: the kind of thing RR does best.

  4. Monika Edvardsen (verified owner)

    A pretty gritty sounding synth, but it can sound quite smooth too, if you turn osc 1 down and osc 3 up. It’s a bit out of tune as it is + you can detune it further by turning up Osc drift (all 3 oscillators drift in unison).
    The Advanced Sine sound has crackles and other flaws, which is fun, but they come at the same time every time you press the (same) key, so I recommend adding a random unipolar modulator on Sample Start and turn it way up (change the group from DFD to Sampler mode first).

    RR’s synths usually have a so-called “Glitch”-button that randomizes all the parameters. No such thing here, which was a bit disappointing. Tubes & Wires is nevertheless easy to use, except a couple of flaws/bugs: The Filter Sustain sliders behave almost like switches since they only yield two values (-inf dB up to one nudge from max, and then it goes to -35 dB at max), and both settings make the sound almost the same. Also, the Chorus Rate knob simply doesn’t work. Bug report sent to RR November 2017. Apart from this, it’s a really lovely and weird synth with a very vintage lab feel to it.

    A straight forward and easy to program 3 oscillator synth, with very gritty oscillators and character aplenty!

    Twelve sliders, six buttons and nineteen (!) knobs just on the front of this baby. Great pads, but I’ve barely gotten past the surface of this thing. The rail voltage knobs add a nice subtle burn to the patches. You get tracks that sound like you maybe blew out a few fuses or risked electrocution playing it. Apparently, it’s safe to operate though. Along with the two Loopscapes you can make long, endlessly morphing tracks with this.

    RR makes some incredible machines that are excellent reproductions of the beasts of the past, and then something like “Tubes&Wires” that’s not like anything else.
