Post

Hi, today we’re introducing Carbon Electra 2, a synth that’s cut from the same cloth as Scaler, with Scale Locking oscillators and filter, plus an in-depth sequencer that can program chords, inversions and substitutions.

Alongside basic waveforms and wavetables, Carbon Electra 2 also offers Waveterrain oscillators, all backed up by 362 presets.

It’s available now for $79 (regular price $99 from July 13), and owners of Carbon Electra 1 can upgrade from the same vendor they made their first purchase from.



Features List

Scale Lock and Musical Control
  • Oscillators can lock to musical scale degrees instead of only traditional pitch values.
    Sequencer can lock to diatonic notes and chords within the selected scale.
    Musical filter can lock to scale notes, incoming chord tones or interval relationships.
    Designed to keep sound design, sequencing and modulation musically connected.
Wave terrain Oscillators
  • All-new Wave terrain oscillator mode based on topographic terrain-style sound generation.
    Upload your own terrain images in .png format to create custom oscillator behaviour.
    Control how the sound interacts with terrain edges in 3D aspect.
    Adjust terrain size and movement for different tonal results.
    A new alternative to wavetable synthesis, with its own movement, texture and character.
    Also includes classic analogue waveforms and wavetable oscillator modes.
Four-Oscillator Synth Engine
  • Four independent oscillators.
    Classic, wavetable and wave terrain oscillator options.
    Per-oscillator pitch, tune, width, cascading FM and position-style controls depending on oscillator type.
    Unison support across oscillators.
    Flexible oscillator blending through the central mixer.
Note and Chord Sequencer
  • Scale-based note and chord sequencer.
    Write freely in chromatic mode or stay locked to the chosen scale.
    Chord mode allows diatonic chord programming.
    Supports chord extensions and inversions.
    Ideal for musical riffs, basslines, arps, chord patterns and evolving harmonic sequences.
Multi-Shape Step Sequencer
  • Multi-shape modulation step sequencer.
    Assignable to multiple parameters.
    Can run independently from the note/chord sequencer.
    Timing can be divided or multiplied against the main sequencer rate.
    Useful for rhythmic movement, filter patterns, pitch modulation, wavetable movement and FX automation.
Musical Filter System
  • New musical filter modes including interval, chord and scale-based behaviour.
    Filter movement can follow musical relationships rather than only static cutoff values.
    Designed for harmonic filtering, resonant movement and scale-aware sound shaping.
    Includes traditional filter controls such as cutoff/offset, resonance, focus/window and keytracking.
Flexible Mixer and Routing
  • Four-channel oscillator mixer.
    Per-oscillator level and panning.
    Re-routable oscillator/filter paths.
    Optional gain boost mode.
    Designed for complex layering and movement between oscillator sources.
Reorderable FX Stack
  • Powerful onboard effects section.
    Includes delay, distortion, chorus, EQ and reverb.
    Effects can be reordered.
    FX parameters can be modulated.
    Designed for creating finished sounds directly inside the instrument.
New Assignable Modulation System
  • Flexible modulation assignment workflow.
    Assign modulation sources to multiple destinations.
    Clear visual destination lists per modulation source.
    Supports LFOs, envelopes, sequencer modulation and performance controls.
Multiple LFOs and Envelopes
  • Three dedicated LFOs.
    Amp envelope and modulation envelope.
    LFO sync, trigger and mono modes.
    Adjustable LFO waveforms and destinations.
    Velocity control for envelope behaviour.
Performance and Voice Controls
  • Main output section with level control.
    Mono, retrigger, legato and limiter options.
    Unison voice controls.
    Detune, width, tune, pitch bend range and glide controls.
    Mod wheel assignment support.
Advanced Preset and Sequence System
  • User sequence area with visual waveform/shape display.
    Save and recall musical sequences and arps.
    Designed for both sound design and musical phrase creation.
    Stronger link between preset design, harmony and performance.
    Includes 362 presets in total, with artist presets from producers including Carl Cox, Timo Garcia, Faze Action and Christian Laffitte.

Excited to give this a go, seems like a nice synth

Same, I didn't see a demo though.

Can’t get the serial to work. Nothing happens when I press activate or try to start a free trial so no idea what it can do atm. I’m on a Mac btw

Go to '/Users/[Your user name]/Library/Scaler Music'

If that folder exists create a folder called "Carbon Electra 2" (Without the quotes but with Cpaitals and spaces) and relaunch the plugin.

Quite nice softsynth with it's own character

2 things i miss

1) voice settings (it is either monophonic or polyphonic (8 voices)). Would like to see 16 voices and a selection possibility (2 thru 16)
2) dedicated random mod source(s). The only way now to get a random mod source (per voice) is by using up a LFO in S/H (or noise). Another solution could be a couple of extra LFO's.

Also, 1 bug i found; one can change the default UI size and save that in the general options as a default. Although when reopening the UI it says the custom set size, the UI actually defaults back to 100%, which is a pain

The GUI looks very good

Is there a way to upgrade if you got CE1 for free through school of synthesis ?

Nice! Is the chorus new in v2? I really like the chorus in v1

Fun synth, dig it, sounds good

Okay, I have no idea what to do. I bought Carbon Electra in 2017 from VST Buzz. I still have the email receipt. Problem is, they moved and are now Audio Plugin deals, which I also have an account with. But they don't have a record of my Carbon Electra purchase. How can I get my discount if nobody has a record of my purchase?

If you’ve got the email receipt maybe try reaching out to Scaler Music support with it and see if they may be able to help

I think back then PluginBoutique was the only shop to sell it, so I’m guessing you got a discount code you redeemed via PB. Try checking your account there.

Just finished a walkthrough/review of Carbon Electra 2.

I was particularly interested in the harmony-aware workflow (Scale Lock and Chord Sequencer) and spent some time exploring the Waveterrain oscillator as well.

Here's the video if anyone is interested:
