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.
UNIVERSAL COMPATIBILITY
Pipe Organs - Peterson ICS, Syndyne, Matters, and MIDI-equipped consoles
Digital Organs - Rodgers, Allen, Johannus, Viscount, Lowrey
Digital Pianos - Yamaha, Roland, Kawai, Nord
Theater Organs - Wurlitzer, legacy instruments with MIDI

Very helpful if your church can’t find a full-time organist!!

Our congregation is in a rural location and our organist retired so we found this app and found an organist to record our services for us so we can use our organ that we have!!! So grateful 💜🙏
Awesome App

Dusti is an organ expert and this app shows off his expertise. As a new organist it has been so helpful as well as educational to have the ability to record, playback, and store my music. Long live the organ! Cheers and thank you!
MUCH needed App

I just started using this app at three different organs, it works amazing for my church’s and allows me to play at multiple churches on sundays!
What's New in WatsonMIDI 1.15.5
Drag and drop to reorder a service. Press, hold, and move any recording into place, and the new order saves on its own.
More reliable importing. Bringing in a large batch of MIDI files no longer stalls or quits when one file is damaged or incomplete. Problem files are set aside so the rest come in cleanly.
Import summary. After an import you get a clear recap of what was added and what was skipped, with the reason for each skipped file, plus Copy and Share to save or send the list.
Accurate recording source. Imported recordings now keep their own organ source instead of picking up whichever profile happens to be active.
