Hi Blaine,
I tried to use ctrlr for my TX81Z but it clogs up my computer big time - even on a 2.5GHz i7 which is crazy... Then I started writing the TX81Z voice analyzer:
I managed to parse TX81Z SysEx messages on this one and display the EG's graphically.
So after I got my HAWK kit I adapted that editor to the Poly 800. Come to think of it - actually Ctrlr is the reason why I wanted to run synth editing from a browser.
