Elastic OSC For iOS Features 24 Different Mutable Instruments Sound Engines, With 8-Voice Polyphony

Developer Oliver Greschke has introduced Elastic OSC, a new software synth for iOS that builds on the open source code of the Mutable Instruments Plaits Eurorack oscillator module.

Elastic OSC features 8-voice polyphony, and 24 synth engine options, based on Plaits. Where Plaits lets you control the main parameters of each synth engine using four knobs, Elastic OSC maps these an X/Y pad, for quick sound exploration.

Here’s what Greschke has to say about Elastic OSC:

“Elastic OSC is a synthesizer app based on the DSP code of the Mutable Instruments Plaits hardware oscillator module (generously made open-source by MI mastermind Émilie Gillet), one of the most beloved (and cloned) oscillator module in the Eurorack modular scene!

Like the original, Elastic OSC comes with a wide variety of possible sounds, from analog-style, FM, and additive sounds to physical modeling, percussive, to even drum sounds.

While Plaits is monophonic, Elastic OSC can also be used in 8-voice polyphonic mode. This means you can use it either as a sophisticated, experimental monophonic sound source, like the original, or as a regular polyphonic keyboard with a wide variety of great sounds. Of course, you can also combine both approaches!

You can play the app using the on-screen keyboard, or via an external keyboard / sequencer — whether it’s a DAW like AUM, Cubasis, Logic (using Elastic OSC as an AUv3 plugin), or external hardware.

The first release of Elastic OSC is for the iOS platform, available as a standalone iOS app or an AUv3 plugin. Desktop versions for Windows and Mac (Audio Unit & VST3) will come at a later time.”

Features:

  • 24 different Sound Engines from MI Plaits DSP code
  • 4 main parameters per synth engine (Frequency, Harmonics, Morph, Harmo)
  • Recordable Modulations/Automations for almost all Parameters with a length of 1, 2 or 4 beats.
  • ADSR Envelope for Amplifier
  • LPG Envelope for Modulations of Timbre, FM, Harmonics
  • Adjustable Velocity effect on Volume and/or LPG Modulation
  • Arpeggiator with different Arp Modes, Rates, Octave Ranges and Skip Notes functionality
  • Master FX:
    • – 5 effects (5 different Overdrive/Distortions, Hi-Low-Filter, Chorus/Flanger, Delay, Reverb)
    • – Automations for all effects parameters
    • – Master Gain and switchable Limiter effect

Pricing and Availability:

Elastic OSC is available now for iOS, with an intro price of $9.99 USD through May 15th (normally $14.99).

  1. excellent! love Emilie’s stuff. ranges from sonorous, to noisy, to roaring, to complete insanity. should have been free though. the porting is mostly slamdunk reharnessing the model after dropping the hardware support code. loading the user wavetables, DX7, and Wave Terrain is some effort though.

    1. “to complete insanity“
      One of the things I look for most these days when considering new sonic adventures any audio tools will allow me. My only complaint which is easily worked around by running it in a host vs standalone, is the absolute imprecise wonky BPM knob. Please just give me a numerical input vs a spastic “dial” control. I use BPM and millisecond conversions in every facet of my sound design and music, so fighting a knob for even a second with no precision just drives me mad lol. Unless I am missing something I could find no numerical input in stand alone mode for BPM adjustments except the knob. Other than that much audio sonic fun.

      1. Haven’t downloaded it yet but running it in a host app will give you the numerical control over BPM. I often forget that and wonder why I can’t tweak BPM.

      2. yeah, i hear you. same here. i keep my phone’s calculator open when working. perhaps the developer can make an adjustment in this product.

        further, while dynamic modulations are essential for Plaits expressiveness, Key Tracking the inputs along with dynamic modulation is one of the unappreciated voicing techniques. Velocity is also key for the Spectral (green) models, the unpitched and percussive models.

        Classic VCF HP is hella fun as well as the heavily hard sync’d VA AUX output; one of my favs.

        i did a port to Prologue using the front panel VCO controls for Plaits models input and modulations control. i love it.
