    Hi just started playing with the Roli lightBlock M. So far so good - when learning the new objects designed to control/play with Blocks, I of course had a look at blocks.pad : the top LEFT corner turning from yellow to blue is easy to get but nowhere do I see the purpose of the RIGHT-corner gray/green triangle... what is the purpose of this one???
