MIDI for the Arduino - Arduino MIDI Library Input Test

Control SurfaceControl Surface is an Arduino library for building MIDI controllers and controlsurfaces.At its core, the library features a flexible MIDI abstraction layerwith support for serial 5-pin DIN MIDI, MIDI over USB, MIDI over BLE, etc.These MIDI interfaces are compatible with a wide range of Arduino boards(a full table can be found here)and are useful in any Arduino MIDI project.In addition to MIDI input/output, Control Surface also provides easy-to-use utilitiesintended for building MIDI controllers, supporting controls that send MIDI messages─ like potentiometers, push buttons, rotary encoders, etc. ─and controls that react to incoming MIDI messages ─ LEDs, displays, and so on.More advanced controls that combine MIDI input and output ─such as motorized faders─ are supported as well.In projects with large numbers of inputs and outputs, Control Surface allows youto seamlessly add multiplexers, shift registers and other port expanders, andtreat them as if they were ordinary GPIO pins.Table of contents¶ Example usage¶ Getting started¶ Documentation¶ Feature overview¶ Supported boards¶ Change log and updatingExample usageAn extensive list of examples can be found in the documentation.Below are a handful of simple examples that give an idea of how the ControlSurface library can be used.Example 1: A complete sketch for a MIDI controller with a potentiometer that sends out MIDIControl Change message can be written in just five lines of code:USBMIDI_Interface midi;CCPotentiometer pot { A0, MIDI_CC::General_Purpose_Controller_1 };void setup() { Control_Surface.begin(); }void loop() { Control_Surface.loop(); }">#include Control_Surface.h>USBMIDI_Interface midi;CCPotentiometer pot { A0, MIDI_CC::General_Purpose_Controller_1 };void setup() { Control_Surface.begin(); }void loop() { Control_Surface.loop(); }Example 2: Larger MIDI controllers can be implemented very easily as well, with clean andeasy to modify code.The following sketch is for 8 potentiometers (connected using an analogmultiplexer) that send out MIDI Control Change messages over USB. A detailedwalkthrough of this example can be found on the Getting Started page. // Include the library USBMIDI_Interface midi; // Instantiate a MIDI Interface to use // Instantiate an analog multiplexerCD74HC4051 mux { A0, // Analog input pin {3, 4, 5} // Address pins S0, S1, S2}; // Create an array of CCPotentiometer objects that send out MIDI Control Change // messages when you turn the potentiometers connected

Setup() function run on every startup of the Arduino System?a) 4b) 5c) 2d) 1View AnswerAnswer: dExplanation: The setup() function is used predominantly to configure the pins, variables, Serial data, etc. and is executed only once throughout the entire cycle of the program. However other than the above-mentioned uses, it can also be used to execute technically all aspects of an Arduino program, but since it only runs one time, it’s not very useful for anything other than configuring.29. Which of the following statements is not true when dealing with the Firmata library?a) The Firmata Library uses the Firmata Protocol for communicating datab) The Firmata Library uses the Midi Message Formatc) The Firmata Library can only be used on an Arduino Unod) The Firmata Library is used to establish communications between the Arduino and the DesktopView AnswerAnswer: cExplanation: The Firmata Library is used for communicating data to and from the computer. This is required when the Arduino is required to store certain data on the computer which would be otherwise too large for the Arduino to store in its internal memory. Other uses of this library are in the field of IOT.30.

Description Bend all audio files to your will with the Adafruit Music Maker shield for Arduino! This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally.All this functionality is implemented in a light-weight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects! But the chip is a pain to solder, and needs a lot of extras. That's why we spun up the best shield, perfect for use with any Arduino Uno, Leonardo or Mega.This version of the shield includes an onboard 3W/channel stereo audio amplifier that can drive 4 or 8 ohm speakers. It's the same amplifier as in our TS2012 breakout, a great class D amplifier that sounds good and is power-conscious for portable/battery usage. Volume control is handled by the VS1053 chip. We also have a version without an amplifier, when only line/headphone out is required.We believe this is the best MP3 playing shield you can get, and at a great price too. Here are some specs:Features the VS1053B codec chip - decodes Ogg Vorbis, MP3/MP2/MP1, MP4, AAC, WMA, FLAC, WAV/PCM, MIDI. Encodes Ogg or WAV/PCMStereo audio out with proper audio filter caps and ground reference so it can be safely connected directly to headphones, a stereo system or other powered speakers7 extra GPIO's that can be written or read through the Arduino Library for reading buttons or lighting LEDsMicroSD card socket, for any FAT16/FAT32 formatted SD card from 64Mb or greater.Full 3.3/5V level shifting for SD and MP3 chipsetsWorks with Arduino Uno, Mega, or LeonardoBuilt

Faders are supported through the tttapa/Control-Surface-Motor-Fader repository.→ Control Surface Motor Fader documentationBank supportAll controls can be arranged in banks: for example, if you have only 4physical faders, you can make them bankable, so they can be used to controlthe volume of many more different tracks. Changing banks can be done using pushbuttons, rotary encoders, etc.Apart from banks and bank selectors, you can also add transposers to changethe key of your notes, for example.Extended input/outputIn order to save some IO pins, the library natively supports multiplexers(e.g. 74HC4051 or 74HC4067) to read many switches or potentiometers,Shift Registers (e.g. 74HC595) to drive many LEDs, MAX7219 LED drivers,etc.→ Extended IO documentationAudioIf you are using a Teensy 3.x or 4.x, you can use it as aUSB audio interface. Just add an I²S DAC (e.g. PCM5102) and 5 lines of code,and you can start playing audio through your Teensy, by combining ControlSurface with the Teensy Audio library.You can also add volume controls and VU meters for these audio connections.→ Teensy Audio documentationModular and extensibleThanks to the structure of the library, you can easily add your own MIDI ordisplay elements, using some minimal, high level code. All low level stuff iscompletely reusable (e.g. all MIDI operations, debouncing switches,filtering analog inputs, and so on).InstallationDownload the repository as a ZIP archive by going to the home page of therepository and clickingthe green Code button in the top right, then choosing “Download ZIP”.Alternatively, click the following direct download link: the Arduino IDE, and go to the Sketch > Include Library > Add .ZIPLibrary menu.Then navigate to your downloads directory where you just downloaded thelibrary.Select it, and click Ok.Supported boardsFor each commit, the continuous integration tests compile the examples for thefollowing boards:Arduino UNOArduino MegaArduino LeonardoTeensy 3.2Teensy 4.1Arduino DueArduino Nano EveryArduino Nano 33 IoTArduino Nano 33 BLEArduino Nano EveryArduino UNO R4 MinimaArduino UNO R4 WiFiESP8266ESP32ESP32-S3Raspberry Pi PicoThis covers a very large part of the Arduino platform, and similar boards willalso work.
