Hey sorry I am afraid I am still missing something.
For the purposes of this, say I am inputting a new note in Step mode. I have put my new note in, and I'm cycling the note info menu:
NOTENUM E 2 - makes sense
VELOCITY 064 - also fine
NOTELEN 000/01 - this is the bit I'm confused on, as to the relation between the 000 and the 01 in this case?
The manual doesn't seem very clear on what these two numbers specifically mean, or I have missed that bit, or (and this is likely) I am just being stupid and it's really obvious
