A few weeks back I emailed ONE4ALL about how much memory the 2 Cinema remotes had. Here's what I received via email from the today:

>>The cinema 7 is a basic learner with one memory "bucket" that handles all learning, macros, etc.

It is difficult to set limits as to how many learning keys, macros depending on size, etc, because all have different complexities and are
all stored in the same place.

We Set the limits as 28 learning keys and two macros of 15 keystrokes each, but this is conservative.<<

There you go. The official word.]
