Properly timed MIDI events
We do not properly time the event the board generates. For instance, in the JACK backend, as soon as an event is generated it is added in the first frame of the sound buffer. On machines were the buffer has to be quite large, it can make the Arpeggigon sound quite bad.
There should be a way to know where in the buffer (i.e. at what frame) the MIDI event the Arpeggigon generate should be added for it to sound good.
