  1. unfortunately roland missed to implement the mega important “are you sure?” question when switching between modes. i lost tons of sequences because of that. sad.

    1. Isn’t there a way to lock the pattern now though?

      From Roland website:

      System version 1.10 added the ability to lock program changes so that unintentional operation of the Value -/+ buttons will not change the program while you’re editing a sound or pattern. T

  2. Computers are binary (base 2). Octal is another one commonly used for computing. Sexagesimal is also interesting, it’s base 60, used for time, angles, etc. It also has a neat name. 🙂
