If you sampled hourly or more often, then it should do fine as a TamTam instrument. :-) There is no usable text editor anyway. (BTW, if a Terminal one will do, I suggest "joe". It's UTF-8 aware, can show a help window while you work, is based on explicit block operations rather than hidden ones, and it highlights the current block.) Anyway, a *.wav file is unquestionably efficient in every way.

I could see that being desirable 1/3 of the time. The rest of the time, a fresh start makes more sense. For many activities, I almost can't imagine ever wanting to restart.
