[embedded content]

Arturia today introduced the PolyBrute, a new 6-voice polyphonic analog synthesizer that’s designed for expressive synthesis.

At its core, it offers 6 analog voices, based on Arturia’s ‘Brute’ oscillators and dual filters. The synth features two Brute oscillators per voice, feeding into dual filters, a Steiner filter and a Moog-style filter. The filters can be patched in series, in parallel, or as a mix of both.

The PolyBrute also offers extensive modulation options, including three LFOs per voice and a matrix modulation patching system.

At the end of the voice path are 3 types of effect – Modulation, Delay, Reverb – that let create effects from Chorus to BitCrusher, Karplus to BBD delay, Plate to Dreamy reverb.

The Arturia PolyBrute synth engine features an A & B ‘state’ for every patch, saving two variations on the parameter settings. When you sweep between those two states, you’re simultaneously altering all relevant parameters – like turning all the knobs at once. You can map PolyBrute’s envelopes, LFOs, aftertouch and sequencer to change the morph position between the two states in real-time.

But what makes the synth unique is the variety and expressive control options it offers.

It starts with a velocity/pressure-sensitive keybed, pitch wheel and assignable mod wheel, and foot pedal controller inputs. Performance options include an Arpeggiator, Matrix Arpeggiator and a 64-step polyphonic step sequencer.

The PolyBrute panel also offers knob-per-function control, for immediacy in performance and sound design. A Morph knob lets you dynamically move between the A & B states for each patch.

The PolyBrute also features the Morphée controller, a sensor that captures three dimensions of expression. You can map the X and Y touch axes, plus the Z pressure axis, to any destination parameters available in the Mod Matrix. You can also use the Morphée to randomize your sequences or arpeggios with spice, dice, and ratcheting effects.

The PolyBrute also includes a ribbon controller. Positioned directly above the keybed, you can assign it to your chosen modulation destination.

For computer integration, Arturia has created PolyBrute Connect, a standalone Mac/PC app and a plugin that lets you organize your patch library and enjoy bi-direction visual editing between software and hardware. This makes it possible to control every PolyBrute parameter via MIDI tracks in your DAW.

Arturia Microfreak Update Adds Vocoder & More

Arturia Microfreak Update Adds Vocoder & More

Arturia has introduced the Arturia MicroFreak Vocoder Edition, an updated version of the MicroFreak that adds a vocoder and new synthesis capabilities.

In addition, they’re releasing a firmware update that brings the new capabilities to all MicroFreak synthesizers.

The MicroFreak Vocoder Edition is essentially the MicroFreak with new styling and a new Gooseneck electret microphone.

The vocoder features 16 frequency bands & 3 waveforms – sawtooth, pulse width and noise. The Timbre and Shape knobs adjust the response of the 16 frequency bands. You can use the removable mic or connect an external sound source via the headphone socket. The mic will be available separately for existing MicroFreak owners.

Here’s an in-depth look, via loopop, at both the MicroFreak Vocoder Edition and using the firmware with existing MicroFreak synths:

Arturia KeyStep Pro Update Adds Improved MIDI, New Recording Options & More

Arturia let us know that they’ve released updated firmware for their KeyStep Pro controller and sequencer.

The new firmware adds a variety of updates based on user feedback, including new features, improvements and fixes.

Here’s what’s new in KeyStep Pro firmware v1.2.6:

  • Reworked MIDI In implementation – Notes sent to the track’s input MIDI channels are now processed as if these were played on the KeyStep Pro keyboard and transmitted to the MIDI and CV Outputs.
  • More recording flexibility with the count in – When recording in real time, notes played prior to the recording are maintained after the start and are now recorded as well.
  • Record several patterns on the fly – Patterns can now be changed while record is ON. This lets you build several patterns at one time leaving more room for your creative flow when jamming.
  • Drum track time division per pattern – The drum track time division is now stored in each drum pattern and recalled when changing from one pattern to another.
  • Sync Auto mode improvement – KeyStep Pro is now able to jump back to its internal clock after having been synced to an external source.
  • Sync handling improvements – Synchronization accuracy has been improved and now supports all clock rate formats.
  • New screen feedback messages – For some actions, new screen messages have been added to make the workflow more intuitive

The update also comes with various bug fixes and workflow improvements. For more details, check out the release notes.

Arturia OB-Xa V Brings Classic Oberheim To Your DAW

Arturia OB-Xa V Brings Classic Oberheim To Your DAW
[embedded content]

Arturia today introduced OB-Xa V, a new software emulation of the classic Oberheim OB-Xa synthesizer.

Here’s what they have to say about it:

“Released in December 1980, the OB-Xa made a massive statement in the world of analog synths. Following the release of accessible digital synthesizers, Oberheim brought in added polyphony, big sound, and impressive power to show the world what synth greatness really means, and it became an instant rival to its main competitor, Sequential Circuits’ Prophet 5.

OB-Xa is a hugely iconic synth behind Van Halen’s hit ‘Jump’ and albums by Prince, Queen, Bon Jovi, Billy Idol, Chaka Khan, The Police, and more. Its dangerous, all-embracing sound is perfect for expressing the epic, heart-crushing drama of life. It’s used today by the likes of Flume, Chrome Sparks, Calvin Harris, and Venetian Snares, entering a new dimension of electronic music.

Our faithful reproduction of OB-Xa with extra inspiration taken from the OB-X and OB-8 for the most satisfying result will be perfect for keyboardists and synth programmers.”
