I'd like an app that can load new banks and program patches into a hardware synth via MIDI. (Compare MIDI-Ox for PC or Sysex Librarian for OSX.) Can you recommend one?

Midi Tool Box

Thank you, carpenzano. That could work. Anything else? The main drawback that I see with Midi Tool Box is that it relies on iTunes file sharing to load and save sysex files. Something that could download from a URL, or Dropbox, would be even better.

Hi David, I just released Sysex Base, which does what you want (recording and transmitting sysex files). It's set up to open .syx files from other apps as well, so you can load them from Dropbox or Mail, etc. You just tap on the file in the app you have it in, and in the action menu there will be an option to "Open in Sysex Base". For now, the file has to have a .syx extension to be recognized by the app.

More info on the app here: https://coffeeshopped.com/sysex-base

Any feedback appreciated!

This looks promising.

Late to the thread, but throwing this out there: Web MIDI works on iPad if you're using a compatible browser (Chrome/Edge). The limitation isn't really iOS vs Android, it's whether the browser implements the Web MIDI API.

Built a browser-native SysEx librarian that runs on anything with Chrome/Edge - iPad included. Handles vintage synths (DX7, Juno-106) that use the old 5-pin MIDI spec via USB-MIDI interface.

The iPad workflow: Camera Connection Kit → USB-MIDI interface → synth. Open browser, instant backup.

Not as slick as a native iOS app, but doesn't require App Store approval gymnastics either.
