Reader Gary (gary909 on github) let us know that he’s shared JT4000M Programmer, a free web-based patch editor for the Behringer JT-4000 Micro Synthesizer.
“Hopefully, it should make creating new sounds on the thing a little bit more fun than going through the menus!” he notes. “It’s been tested running on Chrome and Android, hopefully it should work on most other platforms.”
If you create a sound you want to save, just press down on the ‘Select’ pot, and the sound will overwrite the currently selected sound.
Note: A browser with Web MIDI support is required.

Not for iPhone / iPad?? 🙁 (it would appear).:…. [Probably because safari does not support web MIDI, from what I can see]? – still, it’s a bit of a shame, I could have really used this!, My eyes are starting to go, and small screens are becoming a chore…
This guy’s editors are great… and there’s an Apple-specific version on this page too. (I don’t use that version so can’t comment, but the main VST version is excellent.)

They’re all like 7 EUR/USD.

That’s an excellent way to deliver services not requiring precise timing for crossplaform delivery… omni-banking would be a must !
Respects to Gary
