This library contains code that can replicate the virtual analog synthesis used by the Korg ER-1. It is not guaranteed to sound exactly like an ER-1, the code used in the machines is thus far closed source, but the synthesis techniques chosen for this library were selected and refined based on spectral and waveform analysis of sounds generated from an original Mk1 ER-1.
- The Metaphase Core library
- Google Test for unit testing
This library is designed to be as self-contained as possible, but it is still recommended that one use the MUDS project structure when including this this library into a project. If a MUDS- style project is used, CMake becomes a requirement.
NOTE: The Metaphase Core library requires JUCE to build, but the ER-1 DSP library does not itself depend on JUCE directly or otherwise. This is done to allow this library to be compiled and linked for hardware that may not support traditional JUCE-supported operating systems.
To build unit tests, pass -DBUILD_TESTS=ON to the build script. In this case
JUCE will be required to build as many of the Metaphase Core testing tools rely
on JUCE to simplify basic operations such as audio file format handling.
