Is it possible to add glide or ratcheting to individual steps? I can’t seem to figure out how, although it seems like this should be possible (maybe I missed it in the manual)?
It’s not possible. However you can control all the parameters of the effects via the mod matrix. Maybe use a CC to change e.g. dry/wet of an effect so you could approach a per step application.
Hermod is generally weak with any “step-based” editing. It’s not even possible to edit a single note of a cord. The strength of Hermod is its modulation capabilities. In addition to the four inputs, you can “self-modulate” Hermod internally: modify any parameter in any way by using a modulation track.
