Midi gate lengths not recording, help!

Hi, I’m hoping someone might be able to help with an issue I’m having.

I’m recording in note gate and pitch info via midi digital piano. Making sequences, adding midi fx ext, basic stuff. The Pyramid worked fine, I have not changed my settings as far as I am aware. Recently when recording midi into tracks the Pyramid is not picking up the gate lengths, defaulting it appears to the minimal setting, notes are showing in the arranger display but barely audible due to the very short gate. Have I overlooked a setting? I have been through them all several times unable to rectify the issue! Is it likely to be another memory shortage issue. I have a pretty complex midi setup going out of the pyramid hence not wanting to disconnect everything, but only the one midi in from the keyboard.

My mind boggles!
