It can be a little confusing sometimes when you’re in multi mode and you don’t hear the expected sound because some other multi mode is sync activated and you need to go and see what’s on and not.
So here’s my suggestion for making this easier and also having a shortcut so you don’t need to go in and scroll the menu to turn multi mode sync on/off:
You press Shift+multi mode button and the multi button starts to flash, now the other mode buttons (+B button for filter) is illuminated if sync is on for the selected track. And you can now toggle multi mode sync on/off by pressing the corresponding mode button. Pressing multi button again takes you back.
This would make it very easy to see which multi modes are synced and it would also be a very quick and intuitive way to turn sync modes on/off without screen and menus.
