They are MPE Compatible, and I had fun using the Seaboard Keyboard thing when I had a chance. Did you take the plunge already? I was thinking of trying one!
Total Kyma noob here. I plugged my Seaboard block into my Paca, and yes I did get midi information across multiple channels.
However , I could not work out how to get any of the keyboard synths to receive any of that midi data. It would be great to have a pointer to where I could learn how to do this.
