Elastic OSC is a synthesizer app based on the DSP code of the Mutable Instruments Plaits hardware oscillator module, one of the most beloved (and cloned) oscillator modules 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, and even drum sounds.

Elastic OSC can be used in both monophonic and 8-voice polyphonic modes. You can play the app using the (on-screen) keyboard or an external keyboard or sequencer inside your DAW of choice.

The app focuses on ease of use, featuring two XY pads for intuitive sound manipulation of the OSC engine and the effects. Despite the simplicity of the cleaned-up interface, the sound possibilities are vast – thanks to 24 different oscillator models and the ability to automate parameter changes, as it is possible in all Elastic apps released so far.

A versatile Arpeggiator makes it easy to start with simple ideas or can already create entire sonic worlds.

Elastic OSC includes an integrated help system (tap “?”) to provide explanations for nearly every GUI element, the underlying DSP model, and most of the app’s functionality.

CDM: "Elastic OSC becomes a must on iOS. It’s fun to use as an instrument in your iPad DAW of choice."

SYNTH ANATOMY: "Takes the Mutable Instruments (Plaits) algorithms on a wild trip. A nearly perfect app."

LFOs
LFO 1 is for free, while three additional LFOs can be unlocked via In-App Purchase.

LFO MODULATION TARGETS
• Frequency Amount
• Timbre Amount
• Morph Amount
• Harmonics Amount
• Filter Amount
• Pan Amount

LFO MIX
The MIX view enables you to blend multiple LFOs and define how strongly each active LFO influences a target parameter.
The closer a target is placed to an LFO corner, the stronger its influence.
All active LFOs always sum up to 100% (e.g. LFO1 50%, LFO2 30%, LFO3 20%).

MPE SUPORT (In-App Purchase)

Unlock expressive control and shape sounds with polyphonic aftertouch and per-note gestures.
Map Glide (X), Slide (Y) and Pressure (Z) to synthesis parameters and control them with external MPE controllers or the built-in keyboard (X and Y).

MPE support is available as In-App Purchase. After purchasing, you can create your own MPE setups and store them within presets.

A Lock button lets you keep your current MPE setup while loading other presets — so you can explore sounds without losing your preferred MPE mapping.
You can already play and test the included MPE presets that come with this update (by artist Red Sky Lullaby and others).

3 MPE MODULATION SOURCES
• Glide(X) also called Pitchbend
• Slide (Y) also called Timbre (CC #74)
• Pressure (Y) also called Aftertouch

8 MPE MODULATION TARGETS (bi-polar)
• Frequency Amount
• Timbre Amount
• Morph Amount
• Harmonics Amount
• Engine Amount
• Filter Amount
• LFO1 Amount
• Gain Amount
