The origins
of acid

Many of history’s most iconic and sought-after instruments were not necessarily popular at the time of their introduction; often intended for one thing but transformed by users into something else entirely, ushering entire movements into existence.

When the TB-303 Bass Line synthesizer was released in 1981, it was meant to be a substitute for bass guitars. Its sound was subsequently deemed unrealistic by users, and it was discontinued 3 years later - but when it found its way into the hands of electronic music producers in the late ‘80s, the 303 emerged as something entirely different.

The 303 sound may not have been reminiscent of bass guitars, it proved to be a volatile catalyst that sparked an entire dance music movement. It was in Chicago that the reaction started; artists like Phuture and Sleezy D released tracks featuring crunchy, bubbly, jagged basslines that audiences simply hadn’t heard before.

The culprit? Second-hand 303s, paired up with the hypnotic rhythms of house music. Thus, ‘acid house’ was born, and the quirky bass synth at its core went on to feature heavily in rave, hardcore, psytrance… Today, its sound is a favorite of everyone from Daft Punk to Aphex Twin to Tame Impala, etched into music’s past, ever-prominent in its present - and now, Acid V puts its future in your hands.

This is no ordinary 303 clone. Acid V has been deliberately mutated with fresh and experimental features designed with explosive sonic reactions in mind.

A bigger, better voice

Get deeper and more deranged bassline sounds with a 2-octave range sub oscillator and vibrato that goes from slow detune to audio rate.


The 303 sound is so synonymous with distortion that you can’t have one without the other. We included 14 algorithms to satisfy every crunchy craving.

An evolved sequencer

Acid V features the fast, musical, advanced sequencer 303 fans have always wanted; you can even bounce its unique patterns to MIDI for use with clips and other instruments.

Scales & Transmutation

Alter your sequence’s DNA and create fresh patterns in one click with Transmutation, and lock into musical scales specially curated with modern styles in mind.

Under the hatch

Crack open Acid V’s virtual panel to uncover detailed analog fine-tuning, letting you emulate the specific pitchy, drifty, noisy quirks of genuine vintage units.

Modulation & effects

Create evolving movements & vivid sonic coloration without leaving Acid V’s interface; 3 modulators, 4 FX slots, and 17 FX algorithms for next-gen acid sound.

A closer

Zoom in on the quick-fire workflow of Acid V’s interface, from familiar voice controls to retrofitted modern features.

The advanced

Go from hands-on bass box to acid sound design playground at the touch of a button. Acid V’s Advanced panel lets you dive deep into its sequencing, modulation, and effects for a whole new trip.


Acid V is a sequencing & arpeggiation playground. This dedicated panel blows open every individual element of its powerful sequencing, from scale-based pattern generation to polymetric controls. Whatever your style, quickly build thumping bass sequences, wild mechanical rhythms, and unpredictable patterns that refuse to repeat. It even features over 350 sequence presets to get your grooves off the ground.

3 customizable function generators give you hands-free movement sound design flexibility that far exceeds the capabilities of classic hardware. Choose from familiar LFO-like configurations, or go full custom by drawing your own modulation shapes, and quickly assign them to dozens of parameters across Acid V’s interface.

Transform Acid V’s sound far beyond the sum of its components with 4 FX slots and 17 total FX to choose from, including Pitch-Shift Delay, Super Unison, Multiband Compressor, and more. Turn basslines into swirling stereo soundscapes, resonant rave melodies into crushed industrial textures…


Enjoy an expertly-crafted selection of 150+ presets, from classic bass synth lines to experimental modulated tones for modern production - instantly-gratifying results in a few clicks.

Bass Line

Future Sports

A big beat / breakbeat-style sequence with screaming filter resonance and a heavily-distorted engine.

Three Step

A sequence of just 3 steps is all you need to kickstart Acid V; tweak the controls and enjoy the hypnotic repetition.

Hard Bass


Hard bass sequence with funky modulations and big distortion, great for techno and hard techno. Brightness opens cutoff.

Trance's Waves

Aggressive synthetic bass line, that goes well with your Hard Trance productions. Use Brightness to open the filter. For a perfect result, a BPM of 150 is recommended.


Clean Arp

A classic EDM arp, with subtle injections of glide and vibrato, primed for all kinds of electronic music.


Simple acid arpeggiator. You can try generating accent and slide sequences while tweaking the knobs. Time Macro adds flanger effect.

Melodic Sequence

Three Oh What

Coaxing a huge trance sound out of Acid V with a long reverberated sequence that gradually builds to a euphoric climax.

Smooth Ride

A classic hardline acid sequence showcasing Acid V's gritty, abrasive sound, expanded with a touch of stereo delay.

Rhythmic Sequence


Heavy overtones from distortion. Sounds like oscillator sync. Try saw wave for a different set of overtones. Brightness controls the filter frequency.


Dark atmospheric hard acid riff with pitch delay. Use Brightness to change cutoff.


Uptempo Killer

Uptempo kick. Best in C1 range, 180 to 220 BPM. Time macro controls the impact's pitch modulation made by modulation 3. Brightness macro controls the tone. Movement controls the tone as well, but in a harder way, by moving multifilter's cutoff.

Acid Kick

Techno kick preset. You can change the pitch attack with Time Macro. Brightness and Timbre Macros will give you a more aggressive sound. Movement Macro acts like a filter.
