midicopy.c is a 
simple program that just copies from MIDI In to MIDI out, which (if you're
having problems) can help you verify whether something is a Linux MIDI
problem or an FTAP problem (if midicopy works , your Linux configuration
should be OK for FTAP. HOWEVER, make sure that any sound you're hearing
has been transmitted via the MIDI interface (i.e., that you're not just
hearing your own keyboard playing itself. E.g., you've disabled MIDI LOCAL  
mode on your keyboard). It is also useful, since it allows
allows you to play your keyboard if your system is configured for FTAP
usage (with sound coming from a tone generator separate from the keyboard).
It reads and writes from "/dev/midi", as does 'ftap' itself.
