Sure, 128 SCENEs would offer even more. But "only eight" is enough for now 🙂 you ask is it possible, we cannot answer that question. What would you be willing to give up? (See, that's just as speculative a question... I'd rather not wrestle with such things, because it's not something easily changed) it's all just "wish list stuff"

How are you using the current eight Scenes? We'd be very interested in hearing how and for what purpose you are using the eight current Scenes!

We can only help you with getting the most out of what the instrument can currently do. If you are acting in real time performing on the Montage, you have plenty of options to control things in real time. If you can tell us what you are doing with your eight Scenes perhaps we can make some suggestions for more efficient use of this powerful feature. Let us know. If we have a discussion about such a thing the team would need to know exactly HOW it is being used by musicians/owners.

Anything is possible (by the way) but the engineers first question would be "How is customer using the Scenes?" Before they consider providing more, and who know? There might already be a way to accomplish what you are thinking about.
