+# Challenges
+
+- Compatibility: supporting a wide selection of hardware devices
+- Performance: low compute cost & optimal responsiveness
+- Extensibility: ease of adding more devices
+- Low resolution: reducing graphical elements to their bare minimum
+- Portability: ease of integration in software
+- Modularity: option to aggregate devices
+
+---
+
+# Aproche
+
+- Starting with the Launchpad Pro: common & full-featured 
+- Implement a minimalist widget system
+- Porting [score](https://ossia.io)'s user interface to a grid
+- Drawing from the [remote control plugin](https://ossia.io/score-docs/in-depth/remote.html)
+- Search for Intuitive mappings of physical actions to software functionalities
+- Aim for full integration of the hardware device, allowing complete use of score without a screen, mouse or keyboard
+
+<!-- 
+score contains: 
+Independent timelines, 
+nodal patchers,
+waveform displays, 
+and widgets of all kind

+Heavily rely on WIMP interactions

 # Implementation
 
+- Drawing from [Avendish's GUI toolkit](https://ossia.io/posts/minimum-viable/)
+- Device specifications written as simple c++ aggregates
+- Avoid runtime overhead with reflection
+- Midi sysex to update the entire grid with a single message
+- Available on [codeberg](https://codeberg.org/bugui)
