@slinton Its been a great 10+ years but its time to end this chapter of the Twiddler Saga. The T3 is End of Life.
The good news is that Twiddler4 is now in production and waiting for certification. Once complete, T4 will be ready for sale. In order to temper expectations we can offer no better guidance other than "soon, really soon".
T4 will have every feature the T3 had and more - lots more. Stay tuned. We will have a sign up page up soon for people who want to be informed when the T4 goes on sale.
Until then review the new chord notation and provide your feedback.
