For Jazzmammal and others whose Mojo61 editor is not opening, this is how I worked through it.
I recently purchased a Mojo61 B series. I didn’t know how old it was or which version OS it had but it was pristine. The internal WiFi was fine and I could log onto it with my iPhone or any computer but the internal editor would not open. This was also true with the physical USB cable to the computer. The editor said to please plug in the Mojo61 but the Mojo was already plugged in and sending midi to a multitrack recorder.
I read to try old computers as the OS may be old. None of my “old” computers, some ancient, would open the editor. I wondered if the keyboard had had an internal crash, etc.
Finally I read that the current Edge browser has a IE (Internet Explorer) mode which may open “old websites.” I tried this but the editor still did not open. The browser offered a “fix connection problems” troubleshoot option which I selected but still no help. However when I exited the troubleshooter the Mojo Editor appeared on my screen!
I was able to see I had OS version 1.31 which was about 5 years old. I also knew I wanted to upgrade the OS immediately as then the editor should log on better with current gear and, of course, I could edit the sounds.
I had already downloaded and unzipped OS 1.51 and had it as the only item on a fat32 formatted thumb drive so inserted it in the Mojo.
In the editor I selected update OS but it said “update file not found!” I tried four different thumb drives all formatted Fat32 as the update notes specify and only containing the unzipped OS 1.51 but no success.
Finally I formatted one thumb drive Fat32 but limited the allocation size to 512 bytes. I added the upgrade file, put it in the Mojo61, hit upgrade in the editor and it finally worked! My board is now at 1.51.
Now I easily edit the parameters using the internal WiFi and my IPhone. This is a great board and emotionally fun to play. It lives and seems more than a sample player.
I’m sorry I can’t sustain the organ sounds with the pedal though. I’d like to cheat sometimes in that way but I guess that limitation makes it more authentic. Hopefully, the novel I’ve written here will help someone. Blessings.
