Adrian Mills' 240 KM/H collective sits at the crossing point of several genres that rarely get talked about together: makina's frantic Spanish rave roots, hard trance's piercing lead lines, hard bounce's rubbery groove, and the raw aggression of modern hard techno. That's part of why the sound is hard to pin down with a single plugin recommendation — it needs the rubbery thump of the bass line, the spacey house synth stabs, and the snap of a modern hardstyle screech, often inside the same track. Below are the synths producers actually reach for when building this sound, from the industry-standard workhorses to a couple of free tools that get surprisingly close for zero budget.

Xfer Records Serum 2

Screeches, hardbounce leads, and rubbery synth-basslines

Serum earns its spot at the top of this list because of how directly its tools map onto what this genre needs. The Hyper unison-detune module and the Dimension widening section — both built for thickening and stereo-widening a signal — are exactly what a hardbounce lead or bassline needs to sit wide and forward in a fast, kick-driven mix. Layer in Serum's Warp modes (FM, sync, bend) and you can reshape a basic wavetable into something far more aggressive than its starting waveform without reaching for a second plugin.

The real power for this style shows up in the modulation matrix. Routing an LFO or envelope to Master Tune is the standard move behind the pitched screech glides and snapping accents that define 240 KM/H-style drops, and Serum's fast envelope response makes those pitch bends feel tight rather than sluggish. Combined with its unison stacking (up to 16 voices per oscillator), it's just as capable of building the thick, detuned basslines that carry the low end as it is the screaming leads on top.

Reveal Sound Spire

Eurodance-style supersaws, 2000s trance stabs, and euphoric rave leads

A large part of what makes the 240 KM/H sound distinct from straight hard techno is its makina and Euro-trance DNA, and that's where Spire comes in. Its oscillator engine is built around dense supersaw stacking, which is the same core ingredient behind the bright, anthemic trance leads of the late 90s and 2000s — the sound this genre samples and reinterprets rather than abandons.

Where Spire earns its keep specifically for this style is in how those saws sit in a mix. At 160+ BPM, a lead has very little room to breathe against a hard-hitting kick, and Spire's saw and pluck patches are voiced to cut through cleanly rather than fight for the same frequency space. It's less flexible than Serum for from-scratch sound design, but for fast, ready-to-use rave plucks and stabs that already sound period-correct, it's hard to beat.

Arturia Jup-8000 V

Circuit-modeled supersaw leads and classic JP-8000 runs for makina and hard trance

Where the previous entries approximate the classic trance-lead sound, Jup-8000 V goes straight to the source: it's Arturia's circuit-level recreation of the Roland JP-8000, the hardware that originally defined the supersaw sound this whole genre draws from. That matters for makina and hard trance specifically, since so much of the era's lead and run material was written on the original hardware — having its seven oscillator modes and multimode filter modeled at the circuit level gets you closer to that reference tone than a general-purpose wavetable synth ever will.

It's also built for the kind of fast, repeating run patterns this style leans on. The polyphonic sequencer and multi-arpeggiator (up to four arps running in parallel) make it straightforward to build the rapid, cascading melodic runs that sit between drops, and the 18-engine effects rack includes a trance gate for the rhythmic chopping that's practically a genre signature. For readers chasing the exact JP-8000/JP-8080 tone without hunting down aging hardware, this is the most direct route there is.

u-he Hive 2

Fast-arpeggiated melodies and lightweight rave leads

At 160-170 BPM, plugin weight and envelope speed stop being abstract concerns and start actually limiting what you can write. Hive 2 is built to be lightweight and responsive, which makes it well suited to fast 16th-note arpeggiated patterns that would bog down heavier wavetable engines — a common building block in the rave-lead and melodic-run side of this genre.

Beyond raw speed, Hive 2's built-in effects (its distortion and delay engines in particular) are tuned in a way that suits dance music generally, meaning you can go from a clean arp idea to a usable, mix-ready lead without stacking three additional plugins on the channel. It won't replace Serum or Spire for a signature screech, but for fast, snappy melodic content, it's one of the more efficient tools on this list.

D16 Group Phoscyon 2

Screaming acid lines and distorted resonant riffs

Makina's lineage runs directly through the Roland TB-303's acid sound, and no amount of modern sound design fully substitutes for that specific squelch. Phoscyon 2 is a dedicated 303 emulation, which means it starts from the right place tonally rather than approximating the sound from a general-purpose synth engine.

What makes it particularly useful for 240 KM/H-style production is its onboard distortion section, which lets you push the resonance well past where a stock 303 patch would sit — into harsher, more aggressive territory that suits hard techno and hardbounce accents better than a purist acid-house tone would. It's a specialist tool rather than an all-rounder, but for the screaming acid riffs that sit underneath a hardbounce kick pattern, that specialization is the point.

VPS Avenger 2

Aggressive leads, brutal kicks, and screaming synths for the harder end of the sound

Avenger earns its place here less through raw synthesis flexibility (though it has plenty, combining granular, FM, and feedback synthesis in one engine) and more through its dedicated content. Vengeance's in-house sound designers have built entire expansion packs — Hardstyle X and Hardstyle 1 among them — specifically around brutal kicks, cutting basslines, and screaming leads, which puts genre-appropriate starting points directly in your hands rather than requiring you to sound-design from zero.

For readers who want to move fast rather than spend hours in a modulation matrix, this is the practical argument for Avenger over a more "raw" synth: the expansion library already speaks the language of aggressive, hard-dance-adjacent production, and the underlying engine is powerful enough to take those starting patches much further once you're ready to customize.

Free Alternatives

If budget is the deciding factor, two free tools cover most of what this list is built to do. Vital is a genuinely capable Serum-style wavetable synth with strong FM and wavetable-warping tools, making it well suited to the high-resonance acid screeches and metallic FM shots this genre leans on, and it already has an active community building dedicated hardcore and hardstyle preset banks for it. For the classic VA lead tone that runs through makina and hard trance, The Usual Suspects' free emulations — JE-8086, OSIRUS, and Nodal Red 2X — recreate the Roland JP-8000/8080, Access Virus TI, and Nord Lead 2X at the DSP chip level rather than approximating them algorithmically, which makes them the closest free route to the actual hardware tone this sound was built on.

Processing

None of the synths above will get you all the way to the finished 240 KM/H sound on their own — a large part of that aggressive, hardbounce-ready tone comes from what happens after the synth. Multiband distortion is the key tool here: something like FabFilter Saturn 2 lets you drive different frequency bands independently, so you can push the top end of a lead into harsh, screeching territory while keeping the low-mids controlled enough not to clash with the kick. That band-by-band control matters more in this genre than a single-stage distortion pedal-style plugin would give you, since leads and basses are both fighting for space at high tempo.

For basslines and plucks specifically, a shaping tool like Cableguys DriveShaper or Minimal Audio Rift adds a second layer of character — DriveShaper's per-band waveshaping is well suited to adding grit to offbeat basses without collapsing their punch, while Rift's more extreme distortion algorithms suit readers chasing a rawer, more distorted hard-techno edge. The general rule worth passing on to readers: get the synth patch roughly right first, then use distortion to push it the rest of the way into genre-appropriate aggression, rather than trying to design the whole sound inside the synth alone.
