Changing of size of an array leads to a problem if the new size is not 
available in one block in the memory. In this case, a new memory block 
must be allocated and old data copied to the new one. This happens if 
you have strong fragmented memory usage in your OS - what is hard to 
control because it depends on the rest of applications you run on your 
machine (and the OS you use, of course). Allocating a big memory piece 
before processing is always a good idea.

But, this doesn't answer you question, sorry :-(

Do you use _one_ MIDI out cable? How can you get more than 31250baud, 
then? (see: <http://en.wikipedia.org/wiki/Midi>, sections "The MIDI 
specifications" and "low bandwidth"). Or is it a kind of virtual MIDI 
with higher bandwidth?

br, Piotr
