Has anyone heard anything about whether the Remote / expression pedal will be able to support parameter changes apart from the new morphing feature? I mean, if I have the remote and an expression pedal and I want to change the delay mix parameter, why should I take the morphing feature then? A simple "every paramater can be assigned to an expression pedal" would be a huge step on its own. Afaik, this is only possible at the moment, if you control these parameters via midi CC.
You can take just a single parameter and morph that to achieve what you are after-the concept of morphing covers all those applications. It is totally up to you how complex you want it to be.
