D16 Group Phoscyon 2 – Advanced 303 Acid Bassline Synthesizer

D16 Phoscyon 2

Take the Legendary Acid Bassline Into the Future

D16 Group Phoscyon 2 is a modern acid-line synthesizer designed to capture the unmistakable behavior of the legendary silver bass synthesizer while dramatically expanding what producers can do with the concept.

D16 completely redesigned the signal path for the second generation of Phoscyon, focusing on greater emulation accuracy while introducing modern sequencing, arpeggiation, effects and performance features.

The result is much more than a basic vintage synthesizer recreation.

Phoscyon 2 can deliver familiar squelching acid basslines, screaming resonant sequences and sliding patterns, but its expanded controls and effects architecture also make it a powerful modern electronic-music synthesizer.

The Classic Acid Architecture

The sound that inspired Phoscyon became one of the defining elements of acid house and later influenced techno, trance and countless electronic subgenres.

Its deceptively simple synthesis architecture became famous for several interacting elements:

• Resonant filtering
• Accent
• Slide
• Short repeating sequences
• Real-time cutoff movement
• Distortion
• Performance-based parameter changes

Phoscyon 2 recreates this fundamental workflow while removing many of the limitations associated with vintage hardware.

More Than a Simple Emulation

D16 describes Phoscyon 2 as taking the classic analog acid sound into the future.

The core sound retains the recognizable character producers expect, but additional controls inspired by popular hardware modifications and circuit-bending techniques extend the available sound palette.

This means Phoscyon 2 can remain traditional when you want a familiar acid line or move into significantly more aggressive and experimental territory.

Create Acid Riffs with the Built-In Sequencer

A major part of the Phoscyon 2 workflow is its integrated sequencer.

Acid basslines are heavily influenced by sequencing behavior. The notes themselves are only part of the sound—timing, slides, accents and interaction between individual steps can dramatically alter the resulting phrase.

Phoscyon 2 provides a modern visual approach to creating these sequences.

Patterns can be edited, looped and switched during playback, allowing the plugin to function as both a synthesizer and a performance-oriented pattern generator.

Two Sequencer Workflows

Some musicians enjoy the unconventional workflow associated with classic acid hardware.

Others prefer the speed and clarity of modern graphical sequencing.

Phoscyon 2 is designed to accommodate both approaches by providing two different modes for controlling its sequencer.

This allows experienced acid producers to retain aspects of the traditional workflow while giving newer users a more immediate way to create patterns.

Advanced Arpeggiator

Phoscyon 2 goes beyond a conventional up/down arpeggiator.

Its arpeggiator is designed around creating more deliberate and musically useful motives.

Instead of merely cycling through held notes using predictable travel directions, it allows the producer to prepare a riff template that becomes the basis for generated sequences.

This makes it useful for developing ideas quickly while retaining more control over the musical result.

Music Roulette: Pattern Randomization

Need inspiration?

Phoscyon 2 integrates a sophisticated randomizer directly into its sequencer.

Rather than blindly randomizing every parameter, you can determine which notes and step attributes are allowed to change.

Real-time density control determines how strongly the generated sequence differs from the existing pattern.

This can be particularly effective when:

• Starting a new acid line
• Creating pattern variations
• Producing fills
• Generating alternative sequences
• Breaking repetitive loops
• Experimenting during live performance

Randomize, listen, edit and repeat until something interesting emerges.

Multiple Pattern Trigger Modes

Patterns can be triggered in several ways.

Phoscyon 2 supports:

• MIDI Notes
• MIDI CC
• Graphical interface controls

This flexibility makes the plugin suitable for both studio sequencing and performance.

A MIDI controller can be mapped for hands-on pattern switching, while DAW MIDI notes can automate pattern changes directly inside an arrangement.

Drag-and-Drop Pattern Export

Once you create a sequence you want to keep, Phoscyon 2 provides convenient drag-and-drop export.

A finished pattern can be dragged directly from the plugin into your DAW.

This bridges the gap between the internal sequencer and conventional MIDI arrangement.

Create the initial idea inside Phoscyon 2, drag it into your project and continue arranging it using your DAW’s MIDI editing tools.

19 Distortion Models

Distortion became an essential part of the acid sound.

Phoscyon 2 treats distortion accordingly.

The plugin includes 19 distinctive distortion models, inspired by hardware associated with recognizable acid-production techniques.

This provides a wide range of coloration, from additional harmonic bite to aggressive distorted acid lines.

Rather than requiring a separate distortion plugin immediately after the synth, much of the desired character can be created directly inside Phoscyon 2.

Reorderable Insert Effects

Phoscyon 2’s effects are not locked into one rigid signal chain.

The insert effects can be reordered.

Changing effect order can produce dramatically different results because processing one effect before another changes how each stage responds.

This makes the FX section another creative sound-design component rather than simply a collection of finishing processors.

Live Override

Acid music has always benefited from hands-on performance.

Phoscyon 2’s Live Override functionality allows producers to influence important pattern characteristics while the sequence is running.

You can interact with:

• Accent
• Slide
• Vibrato

This can transform a static sequence into a more animated performance.

It is particularly useful when recording automation or performing with a MIDI controller.

Accent

Accent is one of the defining ingredients of an acid sequence.

Accented steps can respond differently from ordinary notes, producing the dynamic movement associated with classic acid programming.

Strategic accents can make even a simple repeating sequence feel much more animated.

Slide

Slide connects notes together and is another essential component of classic acid sequencing.

Instead of each note behaving as an isolated event, selected notes transition into one another.

Combining Slide with resonance, cutoff automation and Accent is one of the fastest ways to produce recognizable acid phrasing.

303-Style Vibrato

Phoscyon 2 also recreates a distinctive vibrato technique based around alternating notes and note sliding.

Rather than relying on a conventional LFO-only approach, the effect uses alternating notes, with controls providing convenient access to the behavior.

This gives producers another way to introduce motion into acid lines.

More Than 800 Presets and Patterns

Phoscyon 2 ships with substantial factory content.

D16 provides more than 800 presets and patterns.

This content serves two purposes.

First, producers can immediately browse ready-to-use sounds and sequences.

Second, presets provide useful examples of how the synthesis engine, sequencer and effects interact.

Load a preset, examine the settings, change the pattern and create a personalized variation.

Built for Acid House

Phoscyon 2 is naturally at home in acid house.

Use resonant filtering, slides, accents and distortion to create the squelching repeating basslines that define the genre.

The internal sequencer makes it possible to develop complete acid riffs without first programming every detail in your DAW.

Phoscyon 2 for Techno

The instrument is equally useful for techno.

Push distortion harder, automate filter parameters and use the randomizer to create evolving pattern variations.

Phoscyon 2 can generate:

• Acid basslines
• Repetitive techno sequences
• Resonant synth loops
• Distorted rhythmic synths
• Percussive sequences
• Industrial-style electronic textures

Phoscyon 2 for Trance

The characteristic resonant bass sound also became an important part of trance and related electronic genres.

The modern arpeggiator, sequencer and effects make Phoscyon 2 suitable for both classic and contemporary trance-oriented production.

Sound Design Beyond Acid

Despite its obvious inspiration, Phoscyon 2 does not have to be used exclusively for traditional acid basslines.

The extended synthesis controls, distortion models, insert effects and sequencing features can generate:

• Synth basses
• Leads
• Rhythmic effects
• Sequences
• Experimental loops
• Resonant effects
• Electronic percussion-like sounds
• Sound-design textures

This makes Phoscyon 2 useful even when a track does not belong to an explicitly acid-oriented genre.

MIDI Learn

Phoscyon 2 includes MIDI Learn for quick controller assignment.

Map important controls to hardware knobs and faders and the plugin becomes much more performance-oriented.

Cutoff and resonance are obvious choices, but distortion and performance parameters can also become part of a hands-on workflow.

Modern Scalable Interface

Modern studios use displays ranging from compact laptops to high-resolution desktop monitors.

Phoscyon 2 provides:

• Multiple interface sizes
• Light theme
• Dark theme
• HiDPI support
• Retina-friendly display options

This allows the interface to adapt more comfortably to different production environments.
