Well, now I've got sugar running reliably on a third box, I've been  
trying TamTam-37.xo on all three for comparison. All the boxes have  
different hardware, just to complicate matters, but here's what I find.

On the lowest spec box: TamTam runs, without spurious clicking. You  
can quit and restart TamTam succesfully. The latency playing notes on  
the keyboard is pretty bad.

On the "middle" box: TamTam runs, but there is constant buzzing when  
it is active. Keyboard latency seems maybe too sluggish to be playable?
If you terminate TamTam, the process does not exit and has to be  
killed from a shell. You can not restart TamTam unless you exit sugar  
then restart it. If you try and access the TamTam.log from the  
developer console, sugar hangs up, with the sugar-console process  
totally maxed out...

On my "best" box: Very similar to the "middle" box case, except that  
the keyboard latency is more acceptable.

On all three platforms, if you hold a key down for several seconds,  
the sound starts warbling and becomes distorted. really does sound  
like buffer overrun problems, I think.

Is there somewhere I can get at the parameters used to set Csound's  
buffer sizes in TamTam and "tweak" them for my hardware?
