Detailed Description

Per-host quirks for MOTU Digital Performer.

Digital Performer revives the edit controller on preset-load / project-import paths without re-querying the previously published parameter list. Plug-ins that mutate the parameter set via restartComponent(kParamValuesChanged | kParamTitlesChanged) end up with stale labels and stale value-domain bounds in DP's automation lane.

The independent fix layers an additional kReloadComponent notification onto the standard restart bundle when the detected host is Digital Performer. Cubase / Logic / Reaper do not require this — they re-query the parameter list whenever the edit controller is recreated.

Rows covered

• digital_performer_param_list_reload — emit IComponentHandler::kReloadComponent on top of the standard kParamValuesChanged | kParamTitlesChanged notification when the plug-in mutates its parameter list mid-session.

Version handling

Documented across Digital Performer 10.x and 11.x; no fixed release announced. apply_digital_performer fires the flag unconditionally.

Tier status

LessonOnly as of the 2026-05-26 iPlug2-audit batch — documented from Steinberg's VST3 SDK + MOTU Digital Performer Plug-Ins Guide, no in-tree bench yet. Promote to Speculative after the per-symptom isolation tests ship; promote to Validated after Digital Performer bench evidence lands.
