How do MIDI notes work?

MIDI itself does not make sound, it is just a series of messages like “note on,” “note off,” “note/pitch,” “pitchbend,” and many more. A MIDI instrument can be a piece of hardware (electronic keyboard, synthesizer) or part of a software environment (ableton, garageband, digital performer, logic…).

How do I listen to MIDI inputs?

Unlike an audio signal, a MIDI signal contains no inherent “sound”, only instructions on how to tell a digital or virtual instrument to create sound. In order to hear sound, you would need to tell your MIDI keyboard to trigger a “virtual instrument” from within your DAW.

What type of MIDI channel message tells an instrument what notes to play?

program change
Up to now, there is no information to tell the synthesizer what sound must be used to play the notes. The synthesizer would probably use the piano or its default instrument. The MIDI message used to specify the instrument is called a “program change” message.

Why are there 128 MIDI notes?

Because data bytes define which note is played, and the velocity at which it is played, there are 128 possible MIDI notes – more than a piano – and 127 possible key velocities (0 velocity is a special case). Change each number in a MIDI command and a different musical result occurs.

Does MIDI carry sound?

MIDI itself makes no sound. The instrument then produces the sound that’s assigned to that channel, i.e. if it’s a synthesizer then it can be a piano sound or a string sound. MIDI information can be sent as both notes and data. It can also be used to control the patch or program number of any MIDI-equipped device.

What is the difference between MIDI in and out?

A: A MIDI output sends out data that was generated within the device, by playing its keys, turning a knob, moving a performance controller, or operating its internal sequencer. A MIDI thru sends a copy of the data that is entering a device back out, so that it can be routed to additional devices.

Do I need both MIDI In and Out?

We refer to this as a USB-DAW connection (DAW is short for Digital Audio Workstation, meaning a computer running a digital audio/MIDI application such as Ableton Live, Cubase, or Pro Tools). You can send MIDI data both ways, so you only need one cable for both MIDI In and MIDI out.

How is basic MIDI message structured?

Structure of MIDI messages: MIDI message includes a status byte and up to two data bytes. The most significant bit of status byte is set to 1. The 4 low-order bits identify which channel it belongs to (four bits produce 16 possible channels).

What is a MIDI input port?

MIDI = Musical Instrument Digital Interface. Electronic musical devices may have a MIDI connection (keyboards and other instruments). Usually USB today. Earlier devices had a specialized MIDI port (see image on right). Many more higher end interfaces still have MIDI connection ports.

Can I use a MIDI port as an input and output?

However, a port cannot be selected as an input and as an output at the same time. The MIDI selection menu also offers a way to disable the step mode, in order to play with the MIDI device and Flat sounds, without having notes being written on the score. Two different modes are available while using your MIDI devices to input notes on a score :

Why does my MIDI keyboard say note on when I press?

When you are using your MIDI keyboard, something on the keyboard needs to be able to detect that a key has been pressed. If it detects that a key is being pressed, it should switch into “Note On” and play the sound at speed and rate the key was pressed.

How do you input notes into a MIDI sequencer?

The more common way to input the notes into the MIDI sequencer is to use a MIDI instrument. This could be a MIDI keyboard, a synthesizer with MIDI capabilities or a drum machine (and many other things). Below is a picture of my Novation Impulse 49. It is only capable of sending or receiving MIDI signals, it can’t play audio signals.

What are the different modes available when using MIDI devices?

Two different modes are available while using your MIDI devices to input notes on a score : The step mode is the default input mode, automatically activated as soon as you connect a MIDI device to Flat.
