Detailed Description
template<typename T>
singleton ARDOUR::MidiRingBuffer< T >
A RingBuffer for (MIDI) events.
This is simply a wrapper around a raw ringbuffer which writes/reads events as flat placked blobs. The buffer looks like this:
[timestamp][type][size][size bytes of raw MIDI][timestamp][type]size

Read a block of MIDI events from this buffer into a MidiBuffer.
Timestamps of events returned are relative to start (i.e. event with stamp 0 occurred at start), with offset added.

Read the content of an event. This call MUST be immediately preceded by a call to read_prefix (or the returned even will be garbage).
