These must be run from the command prompt, but the basic command is very easy. Example: "mf2t. Have fun.

However, the midi2abc output format dumps tracks fully one by one instead of say 4 measures of each channel, making it extremely hard to know what corresponds to what on another track.

Your opening is right but take a look a midi file specifications this might help you ccarh. Your seeing the ANSI representation of the binary data when you open it in notepad. That's right, I'm multi-talented This example plays parsed MIDI messages using a simple monophonic synthesizer. The delta-times of MIDI track events are stored as variable-length values.

These values are 1 to 4 bytes long, with the most significant bit of each byte serving as a flag. The most significant bit of the final byte is set to 0, and the most significant bit of every other byte is set to 1. There is no gap between a delta-time and the end of the previous MIDI event. The findVariableLength function reads variable-length values like delta-times. It returns the length of the input value and the value itself. First, the function creates a 4-byte vector byteStream , which is set to all zeros.

Then, it pushes a pointer to the beginning of the MIDI event. The function checks the four bytes after the pointer in a loop. For each byte, it checks the most significant bit MSB. Otherwise, it adds the byte to byteStream and continues to the next byte. Once the findVariableLength function reaches the final byte of the variable-length value, it evaluates the bytes collected in byteStream using the polyval function.

The midimsg object does not support meta-events. This example ignores meta-events. To interpret a MIDI message, read the status byte. The status byte is the first byte of a MIDI message. Even though this example ignores Sysex messages and meta-events, it is important to identify these messages and determine their lengths. The lengths of Sysex messages and meta-events are key to determining where the next message starts. Sysex messages have 'F0' or 'F7' as the status byte, and meta-events have 'FF' as the status byte.

Sysex messages and meta-events can be of varying lengths. After the status byte, Sysex messages and meta-events specify event lengths. The event length values are variable-length values like delta-time values.

The length of the event can be determined using the findVariableLength function. For MIDI messages, the message length can be determined by the value of the status byte. However, MIDI files support running status. If the first byte of an incoming message is not a valid status byte, use the status byte of the previous MIDI message. The interpretMessage function returns a status byte, a length, and a vector of bytes.

The status byte is returned to the inner loop in case the next message is a running status message. The length is returned to the inner loop, where it specifies how far to push the inner loop pointer. Finally, the vector of bytes carries the raw binary data of a MIDI message. For Sysex messages and meta-events, interpretMessage returns -1 instead of a vector of bytes. The midimsg object can generate a MIDI message from a struct using the format:. The createMessage function returns a midimsg object and a timestamp.
