A way to see which patterns are used and which are not on the SEQ before loading them.
What is the problem?
I always forget where I saved a pattern, even though I try to do it logically and put them in different squares for different purposes. This, of course, fails because what was logical and rational then is promptly forgotten till the next time.
What do you want to achieve?
If I could see patterns (the button lit up, preferably) that contains tracks with data (tracks that have not been cleared) by pressing the pattern button, possibly with a modifier, that would help me tremendously.
