Last note priority?

I’m not sure what I’m doing wrong. I want to hold down let’s say C1 and before I release I want to press D1. So, I’m holding down C1 and D1 and C1 is sounding. That’s fine. But when I lift off C1, (still holding down D1) nothing sounds. Nada. Shouldn’t D1 sound? I’ve just got a little phatty stage II and it’s really frustrating me. I’ve tried low note, high note, and last note priority but it’s the same for all of those!

Anyone able to help this Moog N00b?

Depending on the envelope settings and legato settings you may not hear a sound. (sustain all the way down and legato on)

If the arp is on that may have an effect.
