The randomize octave is a great feature, though it seems it'll more often than not it'll choose octaves from absolute lowest to highest, like C0-C9 which is usually way too much range for a pattern.
I know this can be edited in step edit mode, but it'd be great if you could adjust the range, say, to randomize octave, but within a 2 or 3-octave range.
Maybe something like shift + hold RAND OCT shows an option on oled screen "Octave range", which can be selected with the menu encoder.
