Boss runs a deep MIDI spec. The DD‑500 has 12 delay modes and an 8‑slot assign system that lets the user route any of 62 CCs to any editable target — the profile maps what the factory gives you. The RE‑202 models 12 Space Echo head configurations, 112 controls, and takes MIDI clock. 2 available now.

12 Space Echo modes — Mode 1 through Mode 12 — 112 controls. Takes MIDI clock.
2 manuals. The DD‑500’s assign system runs 8 slots, each routable to any of 62 MIDI sources — mapping the factory defaults and documenting the space is not the same work as mapping a fixed CC table. The RE‑202 has 112 controls across 12 head configurations. Both rewarded a close read.
