TPXE was born in 2007 as a free editor for Tonal Plexus keyboards. When I stopped making the keyboards about five years ago, I decided to put a small price on the software. This may seem like an odd move, but the idea behind it was to help encourage myself to work on a new app which would replace TPXE, a modern versatile software which would support not only the Tonal Plexus keyboard, but also any other microtonal keyboard geometry. That software took me a few years to develop. Universal Tuning Editor is the result, released in 2018 along with TBX2 (which is now in its second incarnation as TBX2b). Though TPXE has continued to work, it has not been updated since I started work on UTE in 2015, and with the release of OSX Catalina, it will stop working on MacOS. So it is time to retire TPXE from sale, and issue a free public license key for it, valid for both Mac and Windows, so that anyone can download it and unlock it for free, with the caveat that the software is not being maintained so any bugs found won't be fixed. On OS versions that can run it, TPXE can still serve as a good introduction to the Tonal Plexus keyboard, which we're still developing (a new prototype keyboard should be done by spring 2020). The free license key is listed on the TPXE product page.

Enjoy!
