The fifth version is for the Teensy 3.1/3.2, and uses the four Periodic Interval
Timers in the Cortex M4 processor to support up to 4 simultaneous notes.
It uses less CPU time than the polling version, but is limited to 4 notes at a time.
(This was written to experiment with multi-channel multi-Tesla Coil music playing,
where I use Flexible Timer Module FTM0 for generating precise one-shot pulses.
But I ultimately switched to the polling version to play more simultaneous notes.)
