My friend. 
i understand what the problem is. What i’m trying to explain to you is that when you want to improve this feature, you have to consider all the possible implications / use-cases.
If your song is not playing… yes, what you are suggesting would work - you could then round-robin and start at the top left again to go through the next set of 48 patterns etc etc. (I still believe a shortcut combination could be more beneficial and maybe a faster way to achieve this).
For example:
- When you hold the Pattern key
- The Key next to it (Length) would change and show you which Page you are on
- When pressing that button it could round-robin between all the 6 pages
- Then all you have to do is press the pad, so you can to jump to the pattern you want
But when the track is playing, doing what you are doing, is going to instantly switch patterns, which is probably not what a user might want. So you need another solution that works during playback - which is why this wish exists.
That’s what i mean when i say in order to implement this feature completely, there are a lot more use-cases that need to be considered. Because else you’ll just add another feature that doesn’t cover all the possible cases.
