Hello!
Nope, luckily it’s not slides. If you go into the note menu, between the arp and OSC 1 on the top row you’ll see the LGN (length) pot.
turning it will set all notes for that track, if you want to change individual notes you can via PLocks.
experiment with different lengths, it’ll show you values for 1/8 1/4 1/2. A whole bar is 16 (Just looking at the patch I’m working on, but it has a lot of chorus/reverb so it may not be)
