That’s ok 🙂
Terra does offer an MPE output mode. MPE input was examined and considered during the development of Terra, but also proved to be too limiting/incapable from a technical point of view.
From the manual:
TERRA can be synched to an external MIDI clock, but there is no way to control TERRA
via external MIDI due to how radically different and more complex TERRA’s synthesis
control is. It’s a constant and multilayered high-resolution data stream, conveying
the smallest motion of a finger. Confining that unique synthesis to a cage of on/off
MIDI messages would kill 70% of TERRA’s charm, and even MPE wouldn’t help. So we
dropped that idea.
