-/* Latency is defined here to mean the time starting when a
- process becomes ready to run, and ending when the process
- actually runs. Latency is due to contention for the
- processor, usually due to other processes, OS activity
- including device drivers handling interrupts, and
- waiting for the scheduler to suspend the currently running
- process and activate the one that is waiting.
-
- Latency can affect PortMidi applications: if a process fails
- to wake up promptly, MIDI input may sit in the input buffer
- waiting to be handled, and MIDI output may not be generated
- with accurate timing. Using the latency parameter when
- opening a MIDI output port allows the caller to defer timing
- to PortMidi, which in most implementations will pass the
- data on to the OS. By passing timestamps and data to the
- OS kernel, device driver, or even hardware, there are fewer
- sources of latency that can affect the ultimate timing of
- the data. On the other hand, the application must generate
- and deliver the data ahead of the timestamp. The amount by
- which data is computed early must be at least as large as
- the worst-case latency to avoid timing problems.
-
- Latency is even more important in audio applications. If an
- application lets an audio output buffer underflow, an audible
- pop or click is produced. Audio input buffers can overflow,
- causing data to be lost. In general the audio buffers must
- be large enough to buffer the worst-case latency that the
- application will encounter.
-
- This program measures latency by recording the difference
- between the scheduled callback time and the current real time.
- We do not really know the scheduled callback time, so we will
- record the differences between the real time of each callback
- and the real time of the previous callback. Differences that
- are larger than the scheduled difference are recorded. Smaller
- differences indicate the system is recovering from an earlier
- latency, so these are ignored.
- Since printing by the callback process can cause all sorts of
- delays, this program records latency observations in a
- histogram. When the program is stopped, the histogram is
- printed to the console.
-
- Optionally the system can be tested under a load of MIDI input,
- MIDI output, or both. If MIDI input is selected, the callback
- thread will read any waiting MIDI events each iteration. You
- must generate events on this interface for the test to actually
- put any appreciable load on PortMidi. If MIDI output is
- selected, alternating note on and note off events are sent each
- X iterations, where you specify X. For example, with a timer
- callback period of 2ms and X=1, a MIDI event is sent every 2ms.
-
-
- INTERPRETING RESULTS: Time is quantized to 1ms, so there is
- some uncertainty due to rounding. A microsecond latency that
- spans the time when the clock is incremented will be reported
- as a latency of 1. On the other hand, a latency of almost
- 1ms that falls between two clock ticks will be reported as
- zero. In general, if the highest nonzero bin is numbered N,
- then the maximum latency is N+1.

- in a preemptive thread
-
- Notes: if you handle midi I/O from your main program, there will be
- some delay before handling midi messages whenever the program is
- doing something like file I/O, graphical interface updates, etc.
-
- To handle midi with minimal delay, you should do all midi processing
- in a separate, high priority thread. A convenient way to get a high
- priority thread in windows is to use the timer callback provided by
- the PortTime library. That is what we show here.
-
- If the high priority thread writes to a file, prints to the console,
- or does just about anything other than midi processing, this may
- create delays, so all this processing should be off-loaded to the
- "main" process or thread. Communication between threads can be tricky.
- If one thread is writing at the same time the other is reading, very
- tricky race conditions can arise, causing programs to behave
- incorrectly, but only under certain timing conditions -- a terrible
- thing to debug. Advanced programmers know this as a synchronization
- problem. See any operating systems textbook for the complete story.
-
- To avoid synchronization problems, a simple, reliable approach is
- to communicate via messages. PortMidi offers a message queue as a
- datatype, and operations to insert and remove messages. Use two
- queues as follows: midi_to_main transfers messages from the midi
- thread to the main thread, and main_to_midi transfers messages from
- the main thread to the midi thread. Queues are safe for use between
- threads as long as ONE thread writes and ONE thread reads. You must
- NEVER allow two threads to write to the same queue.
-
- This program transposes incoming midi data by an amount controlled
- by the main program. To change the transposition, type an integer
- followed by return. The main program sends this via a message queue
- to the midi thread. To quit, type 'q' followed by return.
-
- The midi thread can also send a pitch to the main program on request.
- Type 'm' followed by return to wait for the next midi message and
- print the pitch.
-
- This program illustrates:
- Midi processing in a high-priority thread.
- Communication with a main process via message queues.

-/* suppose you want low-latency midi-thru processing, but your application
- wants to take advantage of the input buffer and timestamped data so that
- it does not have to operate with very low latency.
-
- This program illustrates how to use a timer callback from PortTime to
- implement a low-latency process that handles midi thru, including correctly
- merging midi data from the application with midi data from the input port.
-
- The main application, which runs in the main program thread, will use an
- interface similar to that of PortMidi, but since PortMidi does not allow
- concurrent threads to share access to a stream, the application will
- call private methods that transfer MIDI messages to and from the timer
- thread. All PortMidi API calls are made from the timer thread.
- */
-
-/* DESIGN
-
-All setup will be done by the main thread. Then, all direct access to
-PortMidi will be handed off to the timer callback thread.
-
-After this hand-off, the main thread will get/send messages via a queue.
-
-The goal is to send incoming messages to the midi output while merging
-any midi data generated by the application. Sysex is a problem here
-because you cannot insert (merge) a midi message while a sysex is in
-progress. There are at least three ways to implement midi thru with
-sysex messages:
-
-1) Turn them off. If your application does not need them, turn them off
- with Pm_SetFilter(midi_in, PM_FILT_ACTIVE | PM_FILT_SYSEX). You will
- not receive sysex (or active sensing messages), so you will not have
- to handle them.
-
-2) Make them atomic. As you receive sysex messages, copy the data into
- a (big) buffer. Ideally, expand the buffer as needed -- sysex messages
- do not have any maximum length. Even more ideally, use a list structure
- and real-time memory allocation to avoid latency in the timer thread.
- When a full sysex message is received, send it to the midi output all
- at once.
-
-3) Process sysex incrementally. Send sysex data to midi output as it
- arrives. Block any non-real-time messages from the application until
- the sysex message completes. There is the risk that an incomplete
- sysex message will block messages forever, so implement a 5-second
- timeout: if no sysex data is seen for 5 seconds, release the block,
- possibly losing the rest of the sysex message.
-
- Application messages must be processed similarly: once started, a
- sysex message will block MIDI THRU processing. We will assume that
- the application will not abort a sysex message, so timeouts are not
- necessary here.
-
-This code implements (3).
-
-Latency is also an issue. PortMidi requires timestamps to be in
-non-decreasing order. Since we'll be operating with a low-latency
-timer thread, we can just set the latency to zero meaning timestamps
-are ignored by PortMidi. This will allow thru to go through with
-minimal latency. The application, however, needs to use timestamps
-because we assume it is high latency (the whole purpose of this
-example is to illustrate how to get low-latency thru with a high-latency
-application.) So the callback thread will implement midi timing by
-observing timestamps. The current timestamp will be available in the
-global variable current_timestamp.
