basically the video teaches you how to find the next chord; 1st chord of the major scale can go to any chord, 2nd chord goes to 5th chord, 4th chord goes to either 1st or 5th chord, 5th chord goes back to 1st chord etc.
so I wanna make a 4-step number sequence generator; the number after 1 can be any number within 1-7, the number after 2 is always 5, 4 to either 1 or 5 etc.
and the sequence can start in any number
This may be a case for programming your own module. The logic would be fairly easy to code and a bit confusing to patch up, by the sounds of it.
I’m just getting started with my Ksoloti Gills after a long hiatus. I’ll see if I can come up with something. I may ask for some help figuring out exactly what you want.
