So, I reloaded firmware fine after the editor screwed up the firmware somehow.
I cannot get the Lil Phatty to play with the Lil Phatty editor.
I have followed the set up instructions for the editor on my Mac. All the rights port selected etc. Move the GUI dials and the Phatty responds. All seems ok there.
The only way I can get sound out of the Lil Phatty when using the editor is by keeping a dial moving on the editor GUI e.g the filter. Let the filter go and the sound stops.
Then everything freezes and says 'Sysex Tuning, Checksum Error'.
Turn it off and then on again and everything is complete gobbledyegook, presets won't select, blank display, scrambled display. It's really screwed

So I then have to reload the firmware.
Anyone experience this before and perhaps have a solution?
Many thanks.
