The OP–Z by Teenage Engineering is a fully portable 16-track sequencer and synthesizer that allows you to sequence on the move – not only music, but lights and visuals as well. This synthesizer is packed full of functions into a small, easily portable and well-designed device. It has a retro look that is playful and slightly sci-fi, with four colour-coded dials that allow you to control pretty much everything and an LED interface that provides feedback as you mix.
