Cant comp a clip

I’m trying to comp a clip (esampler) but I’m getting error message "data received is incomplete’. Why is this happening?

Can you send me more information about the MIDI clip your are trying to comb? Can you send a screenshot of the content of the clip (the MIDI notes) and maybe the video sample(s) your are triggering to contact@ebosuite.com? Cheers, Jeroen
