  1. Concerning the firmware update, is it possible to do this update with an other file than a .exe file for an update through a Linux system with a .deb or a .tar.gz file?
    Thanks for your answer. Best regards. Thierry

  2. dumb question, is there any way to determine which version I’ve currently got running? I have the kickstarter unit.

    • There is no way to tell without connecting it via USB. If you haven’t updated it since the Kickstarter, I’ve put up a few different versions. They’ve mostly been bug fixes, but I did change the basic overdubbing behavior. I’m presently working on version 2.0, in which I’ll be adding some new features and extending existing features. I’ll make sure to send out an update to the Kickstarter backers.
