Oberheim Matrix-6 (SOS Jan 86)

muzines.co.uk

The Oberheim Matrix-6 impresses with its powerful synthesis capabilities, blending traditional analog voicing with cutting-edge digital techniques like waveshaping and FM. This 6-voice polysynth stands out for its versatility and expressive potential, offering a wealth of modulation options that evoke the creativity of modular synth systems. However, it's not for the faint-hearted; its programming complexity, due to an overwhelming array of parameters and somewhat opaque terminology, may deter beginners. The lack of a user-friendly interface, with reliance on membrane switches and a slow editing process, could frustrate even seasoned users. Yet, for those willing to delve into its depths, the Matrix-6 offers a lifetime of sound crafting possibilities, appealing to synth enthusiasts who value creativity over convenience.
