MIDI Batch Processor — High-Volume MIDI Editing Without Manual Work
MIDI Batch Processor is a professional desktop utility for producers, composers, sound designers, and live performers who need to apply consistent transformations to hundreds or thousands of MIDI files at once. Instead of editing one file at a time, load your entire folder and apply pitch, BPM, velocity, length, quantization, humanization, filters, and naming rules in a single batch — with full control and zero risk to the originals.

🎯 Batch Transformation Without Opening a DAW
Transpose, scale-safe transpose, tempo adjust, velocity reshape, note length, quantize, and humanize — apply any one or combine many in one pass.

🔍 Filter Before You Process
Restrict edits to specific tracks or MIDI channels (ideal for drums, melody-only changes, orchestral partials, or large setlist prep).

📦 Massive Library Handling
Drag in dozens or thousands of files — the engine validates each, processes sequentially, isolates errors without stopping the batch, and logs all results.

🧾 Professional File Naming & Output Management
Use smart tokens ({original}, {idx}, {delta}, {vel}) to encode settings in filenames automatically and output to custom destinations with overwrite protection.

📊 Real-Time Progress & Final Report
Watch progress per file with live status, then receive a complete summary with clickable paths, success/fail counts, and transformation notes.

✅ Offline, Cross-Platform, Zero Dependency
Processes entirely on your computer — no network requirement, no DAW required, no cloud round-trip. macOS / Windows / Linux supported.
