Arduino barrel organ / Sudo Null IT News

This publication is a translation of my instructions posted on instructables.com. The project won first place in the DIY Arduino contest 2020 by Instructables

Hello! This is an article about how I made a hurdy-gurdy on Arduino.

Demo

A bit of history

The idea of automatic musical instruments is not new. People have always tried to automate various musical instruments, including the piano.

From the middle of the 18th century until the invention of the gramophone, various automatic instruments existed. These were mainly pianolas and manual street hurdy-gurdies. These tools were automated by mechanics and pneumatics.

The mechanical design used a cam driven roller. Rotating, the cams touched the hammers, which corresponded to the keys of the piano.

At the end of the 19th and beginning of the 20th centuries, more advanced tools appeared, controlled by means of perforated paper tapes. Such instruments used a pneumatic circuit with bellows and pipes, and the holes in the tape played the role of miniature pneumatic valves.

Reading notes

First you need to determine whether the piano key is pressed or not.

Ancient musical instruments use rather complex mechanisms. I can use Arduino and electronic sensors to determine if a key is pressed or not. For example, using an IR sensor or a line sensor. These sensors are widely used in the Arduino world for line racing. They allow you to determine whether the surface under them is white or black.

The idea is the following. Let one IR sensor represent one note and a piano key. There are several sensors. A sheet of paper divided into parallel tracks is placed under the sensor. Tracks consist of black and white areas. The sheet starts moving relative to the sensors. If there is a black area on the track under the sensor, then the key is pressed. If the area is white, the key is released. At the moment when the key passes from the released state to the pressed one, the note starts to sound. The sound is held as long as the area under the sensor remains black.

Using several line sensors at the same time, you can create a kind of electronic piano keyboard, where each sensor corresponds to its own key and note. By arranging black and white areas on a sheet in a certain way and moving the sheet at the right speed, a sequence of notes in a piece of music can be obtained.

I made a keyboard with 40 keys. For this I used five Octoliner modules. The Octoliner module is an eight-channel line sensor. Each module has eight TCRT5000 optocouplers and can be used for 8 different piano keys. The module is controlled by the I2C bus, and it is easy to communicate with the Arduino.

I placed five modules in series to create a single large linear array of 40 (5x8) sensors. You can make a keyboard with fewer keys, or you can make a full size piano keyboard with 88 keys. I chose 40 because that's about half of the keys on a real instrument.

Arduino as midi device

I use Arduino to read signals from all linear sensors. However, the sensors are only capable of informing the Arduino whether a key is pressed or released. In order to get sound at the end, you need to turn Arudino into a MIDI device.

MIDI is a universal digital recording standard for exchanging data between various musical instruments. MIDI devices exchange messages. These messages contain information about the keys pressed, their volume and tone.

The Arduino is capable of translating keystrokes into MIDI messages. I chose an Arduino board that is capable of emulating a USB HID device. By transmitting MIDI messages via the USB port, Arduino turns into a real electronic piano keyboard. With a USB MIDI device, I will be able to extract sound using a synthesizer by simply plugging the Arduino into the computer's USB port.

The choice fell on the Arduino MKR ZERO board. It is capable of emulating USB HID out of the box. The board is very productive, and its large amount of flash is ideal for storing heaps of music presets. I also used a regular tact switch to switch presets and a 16x2 I2C LCD character-generating display to show the current preset.

Construction of the barrel organ

I will not describe the entire construction in detail. The hurdy-gurdy was made the first time and at random. Just for the sake of experiment. There are quite a lot of details here, it's easier to look at the 3D model and specification. I used plexiglass, laser cutting, 3D printing, and materials and mechanics that I had at home to make the parts.

Barrel piano BOM;
CAD 3D model.

I conditionally divided the design into two main parts and called them "rectifier" and "puller". Both parts are attached to the base plate. The straightener is fixed to the base with 65mm M3 studs, and the puller is fixed with printed corners. Fasteners are not shown on the assemblies, but are in the specification.

Rectifier assembly

Rectifier aligns paper music sheet with sheet music before reading and has line sensors installed. The sheet for forty sensors came out wide. Such a sheet can bend and tear during movement. Each note track on the sheet must be directly below the corresponding optocoupler. Therefore, the music sheet must be aligned before reading.

The rectifier is assembled from several plates. The paper sheet is sandwiched between the base and the lid. A small gap of 1-2 mm is made between the lid and the sheet so that the sheet does not bite when moving. Two guide plates are installed on the sides. Five line sensor modules are mounted on a plate at a certain height above the sheet and are attached to the base with four 6mm posts.

Stripper Assembly

This part is for feeding the sheet. She pulls a sheet from the straightener.

Four wheels with rubber rings are mounted on the shafts. They tightly clamp the music sheet. Rotating, these wheels pull the read sheet out of the straightener. The puller is fixed on the base plate with corners. The puller consists of three Plexiglas plates and three 6mm shafts between them. Shafts are fixed in plates with F626ZZ flanged bearings. The bearings are fixed with printed caps.

The shafts are rotated by a flywheel through a belt drive. I used a 2GT belt with no tension. Closed-loop belt 6mm wide with 250 teeth. Such belts and pulleys for them are common in hobby CNC machines and 3D printers, so they are easy to find and buy. Small pulley - purchased GT2 20 6 B6.

Larger pulley homemade, laser cut from Plexiglas. It consists of 4 plates with a thickness of 2 and 4 mm and an aluminum flange for a 6 mm shaft.

Flywheel consists of Plexiglas plate, F625ZZ bearing, 6mm shaft flange and printed handle. The bearing is pressed onto the handle and fixed in the plate with a printed cap.

The wheels pulling the sheet are also prefabricated. Each wheel consists of 4 plates, 3 and 2 mm thick, and a flange for a 6 mm shaft. A rubber o-ring is stretched over the plates. I used a regular o-ring GOST 9833 050-060-58.

Shielding of optocouplers

There are many optocouplers in the barrel organ and they are located very close to each other. With the simultaneous operation of many sensors, their signals can be repeatedly reflected and intersect with each other, which will lead to significant errors in the received data.

I decided to get rid of interference as much as possible, and shielded each optocoupler with a cap. The caps that fit the TCRT5000 optocouplers are very small, I printed them on photopolymer.

Music sheet translation

Preparing a music sheet is perhaps the most tedious task, especially if you are not familiar with musical notation.

So, one line sensor has 8 channels responsible for reading 8 notes. The length of the sensor is 80mm. By placing 5 modules side by side, I get a total length of 400mm. I will add another 5mm of free space around the edges. Thus, the total width of the music sheet is 410 mm.

The width of one note track is equal to the width of one optocoupler and is 5.8mm. The distance between the optocouplers on the sensor is 4.2 mm. The same distance between the note tracks on the sheet.

Notes are divided by duration, where duration is a fraction of a bar. A note can be a whole, half, fourth, eighth, sixteenth, etc. As a basis, I take the duration of the sixteenth note, and assign it a height of 10mm on the sheet. Now the entire sheet can be lined with horizontal lines at 10mm intervals, as this is the minimum step. A 10x5.8mm black rectangle on a track will produce a sixteenth-note sound. A rectangle with a height of 20mm is the eighth, 40mm is the fourth, 80mm is half, 160mm is the whole.

In MIDI format, each note on the piano keyboard has a unique number. These numbers will be assigned to the line sensor channels. When transcribing for myself, I formed a few steps so as not to get confused. I will show on the example of a simple melody "rain rain go away" (c) www.teaching-children-music.com.

Look at all the notes that are used in a piece of music and write down their MIDI numbers in ascending order. This tune uses only three notes of the first octave: E, G and A. Note E of the first octave is MIDI number 64, G is number 67, and A is number 69.
Assign MIDI numbers to line sensor channels. For example, I assign the first channel number 64, the second channel number 67 and the third number 69.
Look at the size of the work. This tune is in 2/4 time. This means that the length from one bar to the next is two notes with a fourth duration. Thus, the height of one measure on the sheet is 40 mm (2 * 80 mm). A complete melody has 4 bars and I can fit all the bar lines.
We translate the work. We paint over rectangular black areas on the sheet in accordance with the duration of the notes.
Correcting the music sheet and removing blots. For example, this melody has two identical eighth notes that sound sequentially in the second, third and fourth measures. On the translated fragment, these two eighth notes have merged into a single fourth note. They must be separated by slightly shortening the duration of the first note. To do this, we reduce the height of the first rectangle, providing an empty white gap.

Translated music

The entire score is too long to physically fit on one sheet of paper. To fit all the notes, I printed them out in parts on several sheets of A1. Then I cut the edges of the sheets to the desired width and glued them sequentially into one large roll. In total, I tried to translate three pieces of music.

XOD and libraries

I use the XOD visual programming environment to flash the Arduino. I use XOD a lot in my projects and this one is no exception. Moreover, all the libraries necessary for the project have already been created by users.

amperka/octoliner is a library from the manufacturer for working with an eight-channel line sensor. It contains all the necessary nodes to quickly get started with the sensor, as well as some nodes for advanced functionality, such as adjusting the brightness / sensitivity of optocouplers or changing the I2C address.

e/midi
e/usb midi
e/serial midi

These are cool custom XOD libraries that allow you to work with the MIDI format. Library e/midi is used to create MIDI messages. Using the e/serial-midi/ and e/usb-midi/ libraries, you can exchange MIDI messages via the serial interface or the Arduino USB port.

The main project patch is in the library gabbapeople/barrel-organ/

Project patch

The hurdy-gurdy patch starts with the initialization of the sensors. Quickstart nodes 9 are used to initialize sensor devices0206 octoliner from library amperka/octoliner . Each device has its own I2C address. The line sensor address can be changed using the example in the library amperka/octoliner . For each sensor node set-brightness sets the brightness of the IR emitters to 1 . Then node set-sensitivity sets the sensitivity of the IR receivers to 0.9 . Separate busbars for five devices DEV1 , DEV2 , DEV3 , DEV4 , DEV5 . The usb-midi-device node creates and stores an instance of the MIDI custom type used to generate and send MIDI messages. There is a delay of 1 second when power is applied. After the parameters of all sensors are initialized, node gate starts to pass continuous pulses through itself.

The program has a preset counter. Each preset corresponds to a specific set of MIDI notes assigned to line sensor channels. Presets are switched with button and node track-charger . The display text-lcd-i2c-16x2 shows which preset is currently active.

Next comes node keyboard . This node accepts the busses of all sensors, bus MIDI , as well as the current value of the preset counter.

Keyboard node

Node keyboard is composite and very large, it is the heart of the device. The structure of a node starts with the sensor buses and the value of the current preset.

Five nodes follow octoliner-read-channels . One such node reads eight analog signals from eight optocouplers on the sensor. The signals are read sequentially and digitized using a simple formula. If signal >=0.7 , then the key is pressed; if not, then she is released. In total, the nodes octoliner-read-channels have 40 output pins numbered from CH0 to CH7 and output 40 boolean values in them.

Next comes the MIDI note number selection based on the preset. One channel can correspond to different notes. The choice of note for a particular channel depends on the current preset. Noda note-switcher selects the desired MIDI number depending on the preset number. Each note is assigned a bus with a unique name, for example - 48_1 , where the first value is the MIDI number, and the second value is the preset number. Logic nodes xor cut off unused buses.

Sorted MIDI number buses go to nodes octave . In total, I made six "octave" nodes from 1 to 6. These nodes correspond to the six octaves of a real piano. Each node octave consists of twelve boolean input pins for twelve MIDI note numbers. For example, for the fourth octave, the input pins will be MIDI numbers 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71. MIDI message via USB port.

Sound output

The barrel organ can be connected to any synthesizer with USB. For example, you can connect it to a Windows computer and use Synthesia. Or connect it to raspberry and use QjackCtl & Qsynth.
