What’s New Version 1.6.0
This update fixes issues with in-app purchases.
• Fixed an issue where the Premium upgrade could get stuck on "Downloading…" and never unlock. After updating, simply launch the app once — any stuck purchase will be cleared automatically.
• Added a notice when a purchase is awaiting approval (e.g. Ask to Buy with Family Sharing). Premium will unlock automatically once the purchase is approved.
If you still experience issues, please try "Restore Purchases" on the purchase screen. Thank you for using MS50G Editor.
Description
MS50G Editor is the only dedicated patch editor for the original ZOOM MS-50G MultiStomp guitar effects pedal.
ZOOM discontinued their official editor for the original MS-50G long ago. MS50G Editor fills that gap — giving you full control over your pedal's patches right from your iPhone.
FEATURES
• Patch Editor
Edit all effect parameters visually with an intuitive interface. Fine-tune your tone without squinting at the tiny pedal screen.
• Backup & Restore
Back up all 50 patches at once. Restore your entire setup or individual patches anytime. Never lose your custom sounds again.
• Real-Time MIDI Transfer
Send edited patches to your MS-50G and receive current settings via USB-MIDI SysEx communication. What you see is what you hear.
• Effect Library
Browse the complete MS-50G effect catalog. View detailed parameter information for every effect.
• Custom Presets
Save your favorite patch configurations as custom presets. Build and organize your personal tone library.
REQUIREMENTS
• ZOOM MS-50G with firmware v3.10
• USB-MIDI interface + Camera Connection Kit (Lightning or USB-C)
• iOS 16.0 or later
IMPORTANT NOTES
• This app is NOT affiliated with ZOOM Corporation.
• The ZOOM MS-50G+ is not supported (use ZOOM's official app instead).
• A powered Camera Connection Kit adapter or separate power supply for the MS-50G is recommended. USB bus power from iOS alone is not guaranteed.
• Effect type swapping within patches is not currently supported.
PRICING
Free download with a 1-week trial of all features. After the trial, a one-time purchase unlocks the patch transfer feature. Editing, browsing, and backup remain free.

Build 884117937v1.3.12026-04-04 17:19:36
New Features
You can now share patches via QR code. Generate a QR code from the patch detail screen, and other users can scan it with their camera or import it from an image.

Build 883718579v1.2.02026-03-25 00:09:02
What's New in Version 1.2.0
【Device Effect Compatibility Check】
The app now automatically detects which effects are installed on your connected device. In the effect selection screen, effects not available on your device are shown in gray so you can tell at a glance. When transferring patches, you'll also see a warning listing any missing effects — preventing unexpected "THRU" entries.
【Other Improvements】
Simplified the restore operation from the library
The operation screen now resets properly when the device is disconnected
Build 882514445v1.02026-03-22 15:41:54
Build 883635619v1.1.02026-03-22 18:03:12
This update includes several UI improvements. Enjoy!
Transfer Warning
A warning alert now appears before transferring patches to your device, notifying you if effects may display as "THRU" due to incompatibility. This applies to all transfer operations — Device Operation, Backup restore, and Library restore.
You can dismiss it permanently or re-enable it from Settings.
Improved User Experience
- Library Save: The "WRITE" button has been renamed to "SAVE" for clearer overwrite behavior.
- Effect Slot Toggle: All 6 effect slots can now be toggled On/Off by tapping in Device Operation view. Slots 4–6 changes are applied when you press Transfer.
- Transfer Timeout Protection: Transfer and restore operations now have timeout protection to prevent the app from hanging if the device stops responding.
- CloudKit Error Messages: Cloud backup errors now show user-friendly messages with retry guidance instead of raw error codes.
