i'm trying to create a practice routine for ii7,V7,Imaj7 in each key.

ii7 = 1 bar
V7 = 1 bar
IMaj7 = 2 bars

each 4 bars would get a 3x repeat, then go to next 4 bars to repeat that section 3x, etc.

i can get a repeat for 1-4 bars, but i don't know how to get a repeat for each subsequent set of 1-4 bars.

any help with this or a link to a specific tutorial for this?
