The Oxo Synth2 synthesizer developed by OXO-Music is now available for free!
In this article, we cover the download details and an overview of Oxo Synth2.
1. What Is OXO-Music Oxo Synth2?
Oxo Synth2 is an open-source synthesizer that faithfully recreates “Synth1”, the classic synth by Daichi Laboratory that has not been updated for many years. It uses the same parameters as Synth1 and can load Synth1 patches (.sy1 files and zip banks) as they are. The synth engine itself is left untouched, while some usability aspects such as MIDI Learn and themes have been improved. According to the developer, the original Synth1 was studied only through its audio output, and no disassembly or decompilation of its binaries was performed.
