EPMS 0.0.1

The Expressive Polyphonic MIDI Serializer is a tool to turn MIDI files into a model-friendly, expressive representation for ML projects.

EPMS: Expressive Polyphonic MIDI Serializer

Introduction

The MIDI (Musical Instrument Digital Interface) protocol is extremely useful - and awesome - when we want to work with digital audio. One of its many utilities is in Machine Learning, where it allows us to train data models to generate musical pieces. However, the current literature lack a tool that transcribes MIDI data to a model-friendly structure while preserving polyphony and the whole expressive dimension of music.

EPMS is being build to address that need. While simultaneously working on a
LSTM that predict and translates musical data between instruments, our PET group from the Institute of Informatics of the Federal University of Rio Grande do Sul (UFRGS) - Brazil, is maintaining and developing this repository.

With the advances of MIDI 2.0 in mind, we're working on merging concepts from Music Information Retrieval (MIR) and Machine Learning (ML) to prepare the ground for future works that can popularize the feeling of making music.

The Concept

The main idea behind the project is to represent a MIDI file in some format that is easy to manipulate and feed to a Machine Learning (ML) model, like a neural network. Simply put, we transform the input file in a Pandas DataFrame where information is stored.

Settings

There are currently 3 setting parameters for the serialization process:

1. RESOLUTION (int): the amount of frames per beat to be recorded.
2. KEYBOARD_SIZE (int): the amount on notes that we'll be tracked by the serializer.
3. KEYBOARD_OFFSET (int): the MIDI value of the first key in our keyboard

For example, we can set the serial parameters like

SETTINGS = {
    'RESOLUTION': 16,
    'KEYBOARD_SIZE': 13,
    'KEYBOARD_OFFSET': 60
}

that will be internally transformed into a serie.

SETTING	VALUE
RESOLUTION	16
KEYBOARD_SIZE	13
KEYBOARD_OFFSET	60

Serialization

Each row in the serial DataFrame corresponds to a frame of the song and each frame is formed in a set of different blocks:

• the Instrument Block, that stores information about instrument qualities

NAME	INSTRUMENT	MIDI_PROGRAM	SOUND

• the Metric Block, that will be our time reference across the song

MEASURE	BEAT	FRAME

• the Environment Block, that provides the musical context of one's model environment

ORIGINAL_KS	TS	TEMPO

• and the Performance Block, that is a piano-roll-like representation that specifies one column for every key in our model's 'artificial piano'. In this block we focus on representing the main expressive characteristics of human musical performances, such as dynamics, syncopations and articulations.
  
  With the settings values as shown before, the Performance Block would be:

C4	C#4	D4	E-4	E4	F4	F#4	G4	G#4	A4	B-4	B4	C5

Finally, our frames will contain MIDI data in the following columns:

NAME	INSTRUMENT	MIDI_PROGRAM	SOUND	MEASURE	BEAT	FRAME	ORIGINAL_KS	TS	TEMPO	A0	B-0	B0	C1	C#1	D1	E-1	E1	F1	F#1	G1	G#1	A1	B-1	B1	C2	C#2	D2	E-2	E2	F2	F#2	G2	G#2	A2	B-2	B2	C3	C#3	D3	E-3	E3	F3	F#3	G3	G#3	A3	B-3	B3	C4	C#4	D4	E-4	E4	F4	F#4	G4	G#4	A4	B-4	B4	C5	C#5	D5	E-5	E5	F5	F#5	G5	G#5	A5	B-5	B5	C6	C#6	D6	E-6	E6	F6	F#6	G6	G#6	A6	B-6	B6	C7	C#7	D7	E-7	E7	F7	F#7	G7	G#7	A7	B-7	B7	C8

Serialization Diagram

Performance Block (PB) Representation

As a group project decision, the values stored in the PB are formatted in a way that we can easily turn one row (one frame) into a Multi Hot Encoded Performance (MHEP) frame, that can be used as input vector for a model that uses Binary Cross Entropy Loss (BCE Loss) to get a rapidly convergent 'what notes should I play?' kind of learning. The main point of this decision is that this way we treat the playing problem as a Classification Problem, that is easier to work on.

In that sense, the data inside the PB is represented in a way where different data types provide different semantic meaning for a note's frame in the performance encoding:

Boolean

False: represent silence, the note is not being played in the frame.

Float32

value: represent that this note is playing in the frame with current scalar velocity value.

Usage and Example

First of all, you must import the package and define the settings for the serializer.

from EMS import serialization, deserialization

SETTINGS = {
    'RESOLUTION': 16,
    'KEYBOARD_SIZE': 88,
    'KEYBOARD_OFFSET': 21
}

Then, to serialize:

serial = serialization.file('test_midi_files/George Benson - Breezin.mid',
                            SETTINGS,
                            save_as='serial.pkl') ## optional

The following is the score for the first flute measure of George Bensons - Breezin:

The serial version of this measure can be seen below, it is a Pandas DataFrame with dimensions (64, 98):
