When you say 0.5, do you mean PCB version, or firmware version?
If PCB, very little was changed between .5 and the later .7, so there is really nothing to be concerned about there.
If firmware, then it sounds more like you have a Shruti, rather than a Shruthi. Similar, but different! Particular so with the case.
Info for the older Shruti is here, incase that is what you needed: http://mutable-instruments.net/shruti1/home
“Whenever you save a patch, it is also transmitted to the MIDI out, as a SysEx block. You can record this into your favorite sequencer and replay it back.”
For example SysEx librarian on OS X, or Elektron’s C6.
Elektron’s C6 is available for windows too.
The Shruti spits out everything it receives to the MIDI out port, so it’ll cause feedback in some setups. Since it won’t send anything more than what it receives (at the exception of saved SysEx), you rarely need to hook the MIDI out back to the computer – the out is more like a “thru” to chain another synth/module.
There are some Shruti-1 firmware files here
As long as you can bring the MIDI transfer mode you haven’t bricked anything. Try a slower transmission speed.
