An electronic instrument's interface can be analysed as a layered model from sound through control and layout to concept and time

Push Turn Move offers a single organising model for reasoning about any electronic instrument’s interface, working outward in layers. It starts with Sound (what is being shaped, and how the instrument visualises it), moves to how a User controls that sound (see the Generation/Routing/Modifying functions), then to Layout (how those controls are physically arranged using design principles such as gestalt grouping, ergonomics, colour and legibility), then to Concept (the overarching instrument idea — DAW, sequencer, MPC, modular, etc.), and finally to Time (the historical/technological moment that makes some interactions feel natural). The value of the model is that it is instrument-agnostic: the same lens explains a hardware synth, a DJ mixer, a Eurorack module, or a phone music app, and it tells a designer or learner where to look when an interface feels good or bad.

Examples

Analysing a TR-909 with the model: Sound = drum voices; Control = step buttons + accent/shuffle; Layout = controls grouped per drum part; Concept = step sequencer; Time = mid-1980s affordable drum machine. The swipe on an iPad feels natural today only because of Time.

Assessment

Pick a familiar instrument (Ableton Push, MiniMoog, TR-808) and walk it through the model’s layers, naming at least Control, Layout, Concept, and how Time shaped it.
