Hertz Instruments: the Swedish virtual drum software for realistic rock and metal productions

Hertz Instruments: the Swedish virtual drum software redefining realism

Founded in Sweden, Hertz Instruments has established itself in just a few years as one of the leading virtual drum references for rock and metal productions. Its promise comes down to one sentence: studio-recorded drums, deeply sampled to deliver mix-ready productions. Where many developers settle for capturing just a few velocity layers, Hertz Instruments pushes the detail to a level rarely reached, with an obsessive attention paid to playing, articulations and the tonal consistency of every kit.

The brand's approach appeals to studio composers and modern metal producers alike: a clear playback engine, a built-in sampler, a full mixer and a MIDI groove player, all gathered in an interface designed for writing fast. The result is a coherent ecosystem covering the main software, additional drum libraries, MIDI grooves and mixing tools. This is the richness we invite you to explore in detail.

The genesis of a developer dedicated to demanding drummers

Hertz Instruments was born from a feeling shared by many producers: generic virtual drums, however practical, struggle to reproduce the life and dynamics of a real drummer. The Swedish brand therefore chose to focus on a specific segment, rock and metal productions, and to excel at it rather than chase versatility at all costs. This deliberate specialisation allowed it to build a strong, instantly recognisable sonic identity.

The developer's approach is based on so-called "deep" sampling: every kit piece is captured with numerous velocity layers and round robins, to avoid the mechanical effect that too often betrays programmed drums. The microphones are chosen and set to sound already mixed, allowing the producer to get a coherent result without spending hours sculpting the sound. This "mix-ready" philosophy is at the heart of every release from the brand.

Over the versions, Hertz Instruments has expanded its catalogue around its flagship software: bundles combining the engine and libraries, themed drum packs, MIDI grooves played by real drummers, and complementary mixing tools. Together they form a complete ecosystem that accompanies the producer from the first sketch to the final mix.

The Hertz Instruments ranges: from engine to libraries

Hertz Drums 2: the engine at the heart of the ecosystem

Hertz Drums 2 is the centrepiece of the brand. This standalone, DAW-compatible software brings together a sampler, a mixer and a MIDI groove player in a single window. The idea is simple: keep the playable kit, the mixing controls and the grooves in view, without juggling between multiple screens. The "human feel" controls let you vary pitch, volume and velocity of hits to break mechanical repetition, while per-piece microphone choices offer fine tonal control before the signal even reaches the track.

The software stands out for its ability to load its own one-shots or multi-track samples, which can then be blended with the Hertz drums by articulation and velocity layer. This is a major asset for producers who want to personalise their sound without leaving the working environment.

The bundles: ready-to-use configurations

To get started quickly, Hertz Instruments offers bundles that pair the engine with a selection of libraries. The Hertz Drums Bundle brings together Hertz Drums 2 and the White, Blue and Red libraries, a clear starting point for rock and modern productions. The Hertz Drums Full Metal Bundle pushes the cursor towards the raw, aggressive tones of modern metal. Finally, the Hertz Drums Complete 1 is the ultimate solution: the entire catalogue of drums, signature packs and MIDI grooves in a single package.

The drum packs: a sound for every register

The additional libraries form the heart of Hertz Instruments' sonic personality. The White Pack targets a modern, balanced drum sound, the Red Pack leans towards energetic rock productions, and the Blue Pack brings a darker, more controlled touch. For extreme productions, the Fame & Fury Pack and the Metal Unlimited Raw Pack deliver raw, punchy timbres shaped for metal. The Grand Rock Kit completes the set with a massive drum kit designed for big choruses.

The MIDI grooves: the playing of real drummers

To bring compositions to life without programming every hit, Hertz Instruments offers MIDI grooves played by renowned drummers. The MIDI Grooves by Daray (drummer of Dimmu Borgir) and the MIDI Grooves by Peter Somos bring authentic, directly usable phrases. The Fame & Fury MIDI Grooves and the Grand Rock MIDI Grooves extend the universe of the eponymous packs with matching grooves. These banks can be previewed directly in the plugin and dropped into the session with a simple drag and drop.

GainStage Pro: the complementary mixing tool

Beyond drums, Hertz Instruments signs Hertz GainStage Pro, a virtual processor dedicated to gain staging and signal shaping. Designed as a mixing utility, it supports the producer in managing levels and colouring the sound, whether it is a Hertz drum kit or any other source. This move into mixing tools confirms the brand's desire to equip the producer at every step of their production chain.

The production philosophy: realism above all

What sets Hertz Instruments apart is a simple conviction: a virtual drum kit is only worth its realism. Each library is recorded in professional studio conditions, with microphones chosen for their character and positioned to capture the kit as a whole as well as up close to each element. The result is a coherent, already balanced sound that fits naturally into a mix without requiring heavy corrective processing.

The developer cares just as much about ergonomics. The mixer and the kit view share the same window as the playable drums, which reduces back-and-forth and speeds up the workflow. The pitch, volume and velocity variation controls offer a rare degree of naturalness, while letting the producer keep control of every parameter. Finally, the ability to load its own samples turns Hertz Drums 2 into a true platform, open to every sonic desire.
