Critic Reviews

OXI Instruments Coral review | MusicRadar

musicradar.com

The OXI Instruments Coral packs impressive sonic capabilities in a compact 14HP module, boasting eight voices and ten sound engines. While its value and potential for future updates are commendable, the learning curve is steep due to a convoluted menu system that demands constant reference to the manual. Users may find the lack of a screen and the reliance on a single encoder for navigation frustrating. Still, once familiarized, this synth offers vast creative possibilities, making it a solid choice for those with limited space. Overall, it's a powerful tool that requires patience.
