one thing with grid integration is that while working on a scene you have to constantly switch between grid/keyboard which can really break the flow. to help with that there will be a grid preview mode for live screen - this way you can try different ops and see the effect immediately. there will be a button combo to turn the grid preview on/off (thinking ctrl-g). this does mean that the icons that are normally in the top row have to either be hidden or rearranged - i think the latter makes more sense, so that you still have them when in grid preview:
another button combo will switch to full grid preview mode where the whole screen is used:
this covers visual part, but we’d still need a way to test grid input as well, so i’m planning to add new ops that will allow you to emulate pressing a button/fader/any other control or just emulate a grid press for given coordinates. one consequence of that which i didn’t realize until i started working on this part - it means you could use trigger scripts to emulate random (or not random, or sequenced…) button presses, and you could use all the grid scenes without an actual grid.
