Hi Atte!

I actually meant the earlier estimate to pertain solely to chuck 
(though it probably applies to other audio applications too).  Running 
chuck across quite a few machines lately (plork powerbooks, windows 
machines, and sometimes linux), latency has seemed consistently 
inconsistent depending on the system.

It's hard to say (at least for me) - much depends on your sound card's 
latency.  ALSA, as far as I know, affords low latency.  Which latency 
are you concerned with?  external MIDI/OSC events or audio I/O latency? 
  or something else?  Sorry I can't provide a more precise answer.  
Perhaps others here can?
