MIDI Recording for Organists
$1.99 · In‑App Purchases · Designed for iPad. Not verified for macOS.
WatsonMIDI™ is the professional MIDI recording and playback app for pipe organ and electronic organ musicians. Developed with over 20 years of organist input, WatsonMIDI™ captures, organizes, and shares your musical performances.
RECORD & PLAYBACK
Capture performances with a single tap. Records all MIDI data including notes, expression pedal movements, and registration changes. Play back through any MIDI-connected organ exactly as performed, or route to virtual organ software like GrandOrgue and Hauptwerk.
ORGANIZED LIBRARY
Build a recording library with custom folders for each venue, season, or occasion. Search instantly across hundreds of recordings. Import existing MIDI files from other systems.
SERVICE PLAYLISTS
Create playlists for worship services, concerts, recitals, and special events. Arrange recordings in any order and play through them seamlessly. Perfect for substitute organists.
PROFESSIONAL FEATURES
Instant transposition - shift playback up or down without re-recording
Tempo adjustment - speed up or slow down for practice
Loop playback - repeat recordings continuously
Play-along mode - play live while a recording plays back
Listening mode - hear playback through your device speakers
MIDI Monitor - view incoming MIDI data in real-time
PROTECT YOUR WORK
Share recordings with military-grade AES-256 encryption. Set play limits and expiration. Your intellectual property stays protected — only WatsonMIDI™ can play your shared content.
MAESTRO - FOR ORGANISTS & TECHNICIANS
For musicians who play multiple instruments and technicians who service them:
Organ Profiling - capture any instrument's complete stop list, divisions, and MIDI channel mapping. Build a profile library of every organ you play or maintain.
Translation Engine - a first for the organ world. Record at one church, play back at another with stops mapped automatically. Tag your existing library with a profile, then translate to any profiled organ — a recording from a Rodgers digital organ can play back on a 43-rank pipe organ.
Professional Tuning - chromatic strobe tuner with four display modes, real-time pitch detection, wireless remote tuning via Bluetooth from inside the chamber, historical temperament support, cents offset, chromatic walk, interval checks, and reference tone generation.

What's New in v1.11.0
Translation Engine - Cross-System Playback (Maestro)
Play recordings from one organ on a completely different organ, even across different MIDI control systems. WatsonMIDI automatically maps stops, remaps keyboard channels, and converts between incompatible MIDI formats in real time.
Expanded Organ Profiling (Maestro)
Profile digital organs that use SysEx state dump stop control. The profiler now detects and captures both standard and extended SysEx header formats.
Save Recording Improvements (All Tiers)
Custom folders now appear in the save dialog - save directly to your own folders without extra steps
Set a default folder so new recordings automatically save where you want them
Playback Improvements (All Tiers)
All stops now reset properly when playback ends on SysEx-based instruments
Improved stability during translated playback
