"option to have independent row for each of the 4 instruments "
There's a new setting ("unlinked edit") to change the behaviour when you press INST:
Default is the way it has been, i.e. when you press INST, you edit the same parameters for each instrument ("linked").
With the new option, the last-used row is stored per instrument, so you can have inst 1: arp user pattern, inst 2: fx, inst 3: matrix..., and edit them independently ("unlinked").
If that makes sense
Related: The case when you press INST while editing a user pattern, and the next instrument doesn't have one active, should also be fixed.
