Update REV2 OS from Linux

Update REV2 OS from Linux
« on: May 23, 2019, 08:56:34 AM »
Hello everyone, as a Linux user I spent time looking for information to update the old OS version 1.1.0.1 of my Prophet REV2

Finally I have managed to update it without installing any additional software, simply and in a few minutes with the "amidi" application.

It would be desirable that this information be attached to the options of Windows and Mac that gives the manufacturer since many of us do not want to use commercial OS systems. It would save us time and contribute to make the instrument more friendly.  ::)

Steps:
1- Create an empty folder and put the file of the new OS there, now Rev2_Main_1.1.5.9.syx
2- Open the folder created in a terminal with administrative permissions.
3- Execute the order: amidi -p hw: 1,0,0 -s Rev2_Main_1.1.5.9.syx -i 100

The firmware will update in a few seconds and the synthesizer will restart

My Linux version: Linux Mint 19.1 Cinnamon (Ubuntu)

More info about amidi:

I hope it is useful

Thanks! I tried doing it from supercollider, but it seems the synth chokes on either the transmission speed or the buffer size and supercollider currently doesn't offer any options to configure these (or maybe it's something that needs to be configured in jack? no idea). But amidi has a -i which apparently just works then. I'll be sure to try it out next time I want to do an update.

Yes. That "-i 100" (in milliseconds) add a delay between each SysEx message. Also, before starting, it is convenient to use the -l option that provides a list of the hardware connected to each MIDI port. In my case the "hw: 1,0,0" corresponded to the REV2.
