The primary challenge was scale. Each icon is used at approximately 3.8mm wide on the panel, meaning any intricate detail or stylisation simply would not survive at that size. Close attention to form, line weight, and graphic density was essential to achieve designs that are immediately legible in practice. Where possible, waveform and diagram graphics common in synth and audio product design were avoided, as these are difficult to distinguish from each other at such a small size on the panel.
