Could you build this?

Partial A ReaScript GUI can be drafted with AI, but building a responsive, low-latency multi-track piano roll inside REAPER's specialized ReaScript/JSFX API requires deep DAW-specific Lua/C++ and MIDI handling expertise.

What it would actually take: This editor requires ReaScript (Lua or C++ ReaImGui/SWS extensions) integrating directly with REAPER's native MIDI take APIs. The difficult parts include managing real-time undo/redo history, sample-accurate MIDI event manipulation across overlapping asynchronous takes, and maintaining a 60 FPS reactive canvas inside a host DAW process. It requires substantial familiarity with DAW internals, REAPER's idiosyncratic C/Lua API, and music software UX paradigms.
