Batch-edit MIDI CCs in seconds

MIDI CC Widget is a fast, focused utility for batch-editing Control Change (CC) data in MIDI files.

Drop files, choose what to remove or keep, optionally set new CC values, and export updated files with a single click. Everything happens locally on your Mac, no cloud processing.

Key features:

• Delete CCs: remove ALL, specific CCs, or "ALL BUT" a whitelist.

• Keep CCs: whitelist specific CC numbers to preserve.

• Set Values: assign precise values (0−127) to selected CCs.

• Smart editing: only CC events are modified, notes, tempo, and other data remain untouched.

• Drag & drop workflow: clear drop zone with hover highlight and instant file listing.

• Presets: save and recall your favorite CC operations; last preset is remembered.

• Batch export: non-destructive export with "Edited_" filename; overwrite protection included.

• Helpful feedback: toasts confirm processing, resets, and list clears.

• Private by design: completely offline; no sign-in or network required.
