I will have a look at it later. I was planning to take it easy -  
that's why I din't post a new version.

You might try to play something you know well in E12, meantone (MM),  
and Pythagorean (P) and see if you hear the difference.

OK. Of course, you are free to write in your own style :-).

It is simplest to use an editor that replaces tabs with spaces. I used  
tab on 4 spaces for some years, until I finally felt 2 was expressive  
enough. One can sometimes get a lot of indentations, especially in  
some languages.

I do not have any limit in the code I posted. One can typically only  
have five or so simultaneous keys on my keyboard due to limitation of  
key roll over, fingers, and so on. With an extra keyboard, one gets up  
to ten voices or so. With the BeeThree, decay can be set as short as  
11 ms, though I use the more ample 16 ms. This is about the time of  
the shortest perceptible time bends (which is shorter than the MIDI  
time resolution, and possibly a reason why MIDI timing may not good
