Elastic OSC Synthesizer
Author View comments Tags Tags: , , ,

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 oscillator engine and the effects. Despite the simplicity of the clean interface, the sound possibilities are vast, thanks to 24 different oscillator models and the ability to automate parameter changes, as is possible in all Elastic apps released so far.

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

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

What’s new in version 2.1:

  • Completely redesigned Preset Browser
  • 34 new presets by Andrea Cichecki
  • New Portamento modes (Legato & Always)
  • New Mod Wheel assignment options
  • Smoother preset switching

LFOs

LFO 1 is included. 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 lets you 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 to 100% (for example: LFO1 50%, LFO2 30%, LFO3 20%).

If you’re using this for marketing, ASO, or rewriting the App Store listing, I can also extract it into clean Markdown, plain text, or a structured document.

Cache Sample Browser for iOS
Author View comments Tags Tags: , ,

CACHE – AUv3 Sample Browser

Browse, play and drag & drop.

CACHE is a fast and simple sample browser for iPhone, iPad, and AUv3 hosts. It lets you open your own sample folders, browse collections instantly, preview audio files, detect sample key, and drag sounds straight into compatible apps and hosts.

Built for producers who work across iOS and iPadOS, CACHE solves a problem that has been strangely overlooked for years: some DAWs and AUv3 hosts still don’t include a proper sample browser. Until now, that often meant digging through Files, switching between apps, and dragging samples in from outside your music workflow. CACHE puts that missing browser exactly where you need it.

Use CACHE to:

  • Browse your own sample folders and subfolders
  • Preview one-shots and loops quickly
  • Detect likely sample key for one-shots
  • Drag samples directly into compatible DAWs, hosts, and apps
  • Access collections from local storage, cloud locations, or external drives

In summary: CACHE is a lightweight sample browser for iOS that lets you quickly navigate your own sound libraries, preview audio files, detect their key, and drag them directly into music apps or AUv3 hosts. It doesn’t store or include samples—it simply gives you a fast, organized way to access and use the ones you already have, wherever they’re saved.

CACHE does not include any samples and does not make sound on its own beyond sample preview. You must supply your own sample folders.

CACHE also does not copy or store your samples internally. It simply bookmarks and browses the folders you choose, so it won’t take up extra storage space with duplicate sample libraries. This makes it especially useful if your sounds live on external storage or outside the app itself.

Cache is available in the AppStore HERE
