Exploring Sonic Diversity with P-4L II 1.0: The Multidimensional Max4Live Synth Inspired by Mutable Instruments' Plaits

P-4L II 1.0, created by ricoL, is a commanding synthesizer specifically designed around the spectacular and trademark Plaits Eurorack module by Mutable Instruments. While it is referenced as a clone, it goes far beyond the primary design and delivers a wholesome modular ecosystem with Plaits as the fundamental sound generator. Besides enriching the sound generation capabilities, it accommodates an independent oscillator for every voice in Poly or Unison modes, with a total of seven voices. Thus, essentially, P-4L II 1.0 brings seven Plaits oscillators to the table, significantly enriching the sonic plot.

Imagine having a modular synth equipped with seven reproductions of Plaits. You wouldn't want to confine to identical settings for each one. Keeping that perspective intact, the P-4L II 1.0 was designed as a multi-timbral instrument facilitating unique settings for all significant parameters for each voice. To accomplish this, per-voice variation controls are employed that evenly distribute parameter values above and below the set knob value, simultaneously maintaining a simplistic user-interface.

The elaborate list of features includes all sound engines and capabilities from the original Plaits, counting 16 Models, internal envelope, low pass gate emulation, all patchable inputs, and attenuverters amongst others.

Moreover, the P-4L II 1.0 accommodates several global ‘modules’ such as two intricate multi-mode LFOs (tempo-synced or free running), a Random Voltage Generator showcasing four custom algorithms, a velocity-sensitive ADSR with dual switchable response curves, a clock generator, and an extensive modulation patch bay for attenuating signals.

Each voice, up to a total of seven in P-4L II, contains a virtual Plaits oscillator featuring internal envelope/LPG, specific level control, dual outputs, and more. Further expanding the depth of control, it includes a ladder filter, a manual voltage offset-driven Sample & Hold, an independent oscillator output for audio-rate self-modulation, and much more.

Other delightful features encapsulated in P-4L II are modulation attenuation and inversion incorporated into parameter knobs, four pitch-detune modes comprising Prog, Equal, Power, and Drift, a momentary octave shift control, adjustable width, panning each voice in the stereo field, and MIDI velocity, aftertouch, and key tracking as modulation sources.

Further sweetening the deal is the seamless Ableton Push integration and automatic random patching. Add to that, the original Plaits code by Émilie Gillet gives life to this marvellous device. However, note that P-4L II is not a Mutable Instruments Product.

The P-4L II 1.0 is created for use with Ableton Live, and Live Suite or a Max for Live License is required to run it. At present, it operates exclusively on Mac. The device is available to download via ricoL's Gumroad page at https://ricola.gumroad.com/l/P_4LII or on MaxforLive's library page at https://maxforlive.com/library/device/9966/p-4l-ii.

The P-4L II 1.0 sets new standards for sonic variety in a compact, virtual format, making it an enticing option for electronic music lovers wanting to expand their creative palette. As such, it's a noteworthy testament to Mutable Instruments' creative legacy.

Example Usage

Imagine stepping into a sonic garden, where each plant sings in a different voice. That's the kind of exploratory delight the P-4L II 1.0 can bring to your Ableton Live set. Let's start simple, nurturing one 'plant' before we cultivate the entire garden.

First, make sure you've installed the P-4L II 1.0 correctly. Drag the device onto a MIDI track in Ableton Live.

Let's begin by selecting a Model. Click on the Model Selector to cycle through the 16 different sound engines until you find the 'Virtual Analog' model. This is a great starting point, providing you with a classic, rich waveform.

Now, let’s shape the sound with the internal envelope. Adjust the decay and sustain to taste to create a plucky bass, or a sustained pad. Remember, in the virtual modular world of P-4L II 1.0, your adjustments are like watering the plant - too much or too little changes its character drastically.

For movement, go to the LFO section and select the first LFO. Set it to a slow rate for a gentle sway or a fast rate for a nervous flutter. Map the LFO to modulate the 'Timbre' of the Virtual Analog model by patching it in the modulation section, and watch as your sound transforms over time like a breeze through leaves.

Next, sprinkle some spontaneity with the Random Voltage Generator. Set one of the custom algorithms and map it to the 'Morph' parameter in the modulation section. With each note pressed, Morph will be slightly different, making your melody line organic and ever-evolving.

Craving some texture? Introduce some grit with the built-in ladder filter. Choose from six filter types and turn up the drive for warmth or aggression.

Try the polyphonic capability for a lush chord progression. Experiment with the per-voice variation controls for slight detuning or variations in timbre and envelope settings – it’s like each note in your chord is its own unique plant, thriving with individual care.

Finally, bind everything together with the onboard ADSR to tailor the overall dynamics of your sound, and the clock generator to keep your LFOs and sequences in sync.

As you grow more familiar with P-4L II 1.0, you'll be ready to cultivate a whole ecosystem of sound. Yet, even as a novice, you've begun to explore the vast potential within this digital modular environment, creating music that's as diverse and dynamic as nature itself.

Imagine creating a dynamically textured pad that morphs and evolves over time using the P-4L II 1.0 in Ableton Live. Here's how you can use this versatile synth to sculpt an expressive, multi-layered soundscape:

  1. Initiating the Pad Sound: - Load the P-4L II device onto a MIDI track in Ableton Live. - Select a soft and rounded model from the 16 available sound engines, such as the 'Granular Formant' or 'Wavetable' setting for an ethereal starting point.
  2. Crafting the Timbre: - Tweak the Harmonics and Morph knobs to discover a sweet spot where the pad has a complex but listenable character. - Apply subtle modulation to these parameters using LFO1 set to a slow rate, ensuring the movement of the sound.
  3. Per-Voice Variation: - Engage the Per-Voice Variation controls for the Harmonics and Morph parameters, setting them to slightly detune each voice from each other, which adds a rich, chorused quality to the pad. - Experiment with different positions of the Spread parameter to widen the sound across the stereo field.
  4. Evolving Movement: - Employ the Random Voltage Generator, set to a S&H algorithm synced to a slow rate, as a modulation source for the timbre parameters. This creates a non-repetitive, evolving texture. - For added expression, map MIDI velocity or aftertouch as another modulation source for the main envelope or filter cutoff.
  5. Filter and Resonance: - Adjust the multi-mode ladder filter to taste, opting for a low-pass setting to maintain a smooth top-end. - Set the filter drive moderately to introduce warmth and a bit of saturation.
  6. Adding Dynamics: - Tweak the ADSR envelope to have a long attack and release, giving the pad a breathing quality. - The envelope can further shape the dynamics of the pad, giving life to the sound.
  7. Final Touches: - Utilize the detune modes and momentary octave shift for additional pitch variation and to add interest during certain sections of your composition. - Assign the two complex LFOs to modulate parameters like filter cutoff and resonance, giving the pad an organic, pulsating feel at a relaxed tempo.
  8. Creating a Scene: - Record a progression of chords or hold a single chord and let the sound develop over time. - After recording, automate the modulation sources or introduce new modulations during the arrangement to keep the pad sound evolving throughout the track.

With this setup, your pad will gain a life of its own and showcase a sonic journey that is not only multilayered but also deeply nuanced due to the interactions between the various modulation sources and per-voice variations. Remember to take advantage of P-4L II's Push integration for tactile, hands-on control as you fine-tune your evolving pad.

Further Thoughts

Let's dive deep into harnessing the full potential of P-4L II 1.0's multi-timbral capabilities to create a rich, evolving soundscape for a piece of ambient music.

We begin by setting up an instance of P-4L II on a new MIDI track in Ableton Live. Our aim is to utilize different models across the seven voices for maximum diversity.

Firstly, we set each of the Plaits models to a distinct choice across the seven voices. Utilize the Digital Noise model for voice 1, the Modal Resonator for voice 2, and continue choosing unique models that cater to ambient textures, such as the Wavetable, Physical Modeling, and Granular Clouds, for the remaining voices.

Now comes the creative engine of our sound design – the per-voice variation controls. Adjust the Timbre, Morph, and Harmonics knobs while also playing with the per-voice variation spread, giving each voice a slightly different tonal coloration. The trick to achieving a deep, dynamic sonic palette is to not stray too far from the central knob positions. Small variations often yield the most musical results.

To add movement and unpredictability, we utilize P-4L II's global LFOs and random voltage generator. Map one LFO to the global pitch with slight modulation depth for a subtle drifting quality, reminiscent of tape warbles. Use the random voltage generator to modulate parameters such as filter cutoff and resonance, ensuring to set each voice with slightly different random sequences.

Enable audio-rate self-modulation on a couple of the voices by routing the independent oscillator output to modulate the oscillator pitch. This creates interesting sidebands and harmonics that evolve over time.

Delve into the ADSR section to create different envelope shapes for each voice, making some pad-like with slow attacks while others have faster, plucky responses. Couple the modulation routing with velocity sensitivity and aftertouch for expressive playing dynamics.

Employ P-4L II's detune modes for adding a sense of width and depth, slightly detuning voices with the 'Drift' mode to emulate analogue unpredictability. Utilize the momentary octave shift control, mapped to a MIDI controller, to introduce transient melodic shifts within the soundscape.

Finally, sculpt the stereo field using the voice panning feature by strategically placing each voice at different points within the stereo image. This spatial distribution enriches the listening experience, making the ambient soundscape breathe and evolve in a truly three-dimensional audio space.

To complete this setup, dynamic changes could be automated within Ableton Live, such as gradually modifying the spread of per-voice variations or increasing LFO rates over time to build intensity.

With these steps, you can create a multidimensional, evolving ambient piece that showcases the versatility of P-4L II as a powerful instrument for achieving lush, atmospheric textures inspired by the iconic Mutable Instruments' Plaits.
