What I want is a sequencer, similar to how the Akai Fire works for FL Studio (and also works for Live with a script by isotonikstudios).
The Akai Fire has fixed pads arranged 4 x 16. The 4 horizontal rows correspond to a drum (note) in the DAW, and the 16 columns correspond to a note event over time (4/4, 4 bars).
If applied to Lightpads, each block could contain the same 4x4 layout available in Drum Pad mode, but would be expandable horizontally (so using 4 Lighpads would create the same 4 x 16 pad layout found on the Akai Fire).
This would be an amazing tool to have work in any DAW and it would provide another level of usability/flexibility to the Lightpads.
I have a Push 2 controller for Live, but a 4 x 16 pad layout would be a lovely addition to my workflow (and a great excuse to pick up more of the Roli Lightpads).
