## What is MS50G Editor?

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.

The app now automatically detects which effects are installed on your connected device.

Simplified the restore operation from the library
The operation screen now resets properly when the device is disconnected
