Tutorial works great! I made the mistake of not hooking up the 'keyboard pico 1' agent's 'key output' to 'kgroup 1' 'mode key input'. We hadn't worked with the 'keyboard pico 1' agent, so glossed right over that in the tutorial. But after I made the wiring, all was well. Mode key switch works as expected.
I set mine up just like typical Pico factory setup, with the top, left round key as the mode key. I used Geert's suggestion of 'mode key row' set to 3 and 'mode key column' set to 2. Again, works great.
BTW: If you want to set the Pico keyboard up as 'normal', you need to modify the 'krgoup 1' 'course size' and 'key map' parameters.
PICO
course size -> [[16,0.0]]
key map -> [[1,1],[2,2],[3,3],[4,4],[10,5],[11,6],[12,7],[13,8],
[5,9],[6,10],[7,11],[8,12],[14,13],[15,14],[16,15],[17,16]]
For Tau:
TAU
kgroup 1
course size -> [[16,0.0],[16,4.0],[19,4.0],[19,4.0]]
key map ->
[[1,1],[2,2],[3,3],[4,4],[5,5],[6,6],[7,7],[8,8],[9,9],[10,10],
[11,11],[12,12],[13,13],[14,14],[15,15],[16,16],[17,17],[18,18],
[19,19],[20,20],[21,21],[22,22],[23,23],[24,24],[25,25],[26,26],
[27,27],[28,28],[29,29],[30,30],[31,31],[32,32],[33,33],[34,34],
[35,35],[36,36],[37,37],[38,38],[39,39],[40,40],[41,41],[42,42],
[43,43],[44,44],[45,45],[46,46],[47,47],[48,48],[49,49],[50,50],
[51,51],[53,52],[54,53],[55,54],[56,55],[57,56],[58,57],[59,58],
[60,59],[61,60],[62,61],[63,62],[64,63],[65,64],[66,65],[67,66],
[68,67],[69,68],[70,69],[71,70]]
Note: The 'key map' settings need to be all on one line.
