This is a direct 1:1 port of Audio Damage's Eos 2 desktop plug-in, identical in every way to the Eos you know and love.

New version 2.1
Old version 2.0.203
Release Notes We are very pleased to bring you this major update to one of our flagship products.  1. NEW USER INTERFACE. For Eos’ 10th birthday, we have given it a facelift, and brought It up to date and more in line with our younger products. 2. COMPLETE REFACTORING. Internally, we have replaced most of what we call the “old framework” (which is to say code from before we made iOS products) with our current cross-platform parameter management and support code. This results in a future-proofed Eos that is built to all current plugin standards, and which uses all the latest SDKs and APIs. 3. BETTER CROSS-PLATFORM COMPATIBILITY. The original iOS version of Eos was a separate build process from the desktop Eos. Now, they are identical in all respects, built from the same code-base.
