== '''What the code does - description by Marcos Daniel'''==
<pre>
It is a stress test, the program generates a MIDI file with ten glissandi 
from the lowest A to the top C, (on white keys).
The damper pedal is down during each glissandi.
In the first try, every note takes is played 100ms after the previous one. 
The program asks if there was an error in the playback, if there is not 
overload, you press "y" and it will generate another MIDI file, this time 
with 50ms between notes.
So the sequence of notes duration is (geometric progression) 100ms, 50ms, 
25ms, 12.5ms, 6.25 ms, and so on.
When the computing power is not enough, an overload will occur, let's suppose 
it happens whith 12.5ms of delay, then the next delay will be the average of 
12.5ms and 25ms (the lowest time without overload) = 18.75ms, if there is 
not error, next duration will be average between this last value and the 
maximum time with error, i.e. (18.75 + 12.5)/2 = 15.625ms.
By doing this, quiclky one obtains a final result (10 or 12 tries), and when 
asked pressing key "t" (for terminate) the program exits.
Any run can be skipped by ctrl+c.
The program is "as is", and in Spanish.
At last, but not least, on odroid XU4, it run more consistentlyif you run 
Pianoteq (or this test) from big cores excluding small ones, this can be 
done by taskset command, in case of XU4, big cores are numbered from 
4 to 7, so the command would be 
taskset 0xF0 [command]. There is some improvement if you use less niceness, 
for instance I ran most testst this way:
nice -10 taskset 0xF0 ./ptq_bench
Pianoteq executable file must be in the same folder and version removed, 
simply named "Pianoteq".
