Setup Your Device

Before creating music with MIDI, ensure your device (MIDI keyboard or controller) is correctly connected to your computer. This can typically be done via USB or a specific MIDI cable.

Choose A Digital Audio Workstation (DAW)

You’ll use this software to create, record, and manipulate your MIDI information.

GarageBand, Ableton Live, and Pro Tools are a few examples.

Create Or Import MIDI Information

Most DAWs have a “piano roll” where you can create new (or import existing) MIDI sequences.

Edit And Arrange

This step involves manipulating the notes of your sequence. Your DAW will allow for profound manipulation, like altering pitch, duration, and velocity, even after the message has been recorded.

Assign Sounds and Instrumentation

Remember that MIDI doesn’t produce sound on its own. So it’s crucial to assign an instrument or sound source (also known as plugins or VSTs) to transform these messages into audial bliss!

Adhering to this straightforward guide is a solid foundation for any audio enthusiast delving into using MIDI for their musical journey.

Pros and Cons of MIDI

As with all technologies, MIDI comes with many strengths and pitfalls. It’s like a double-edged sword, equally potent on both sides.

Here, we dive into the various pros and cons that accompany this music protocol system.

Pros of MIDI

There are several considerable advantages to using MIDI in music production and performance.

Versatility in Control and Triggering

One of the significant advantages of MIDI is its remarkable versatility. MIDI can be programmed to control and trigger a vast array of devices.

From synthesizers, sequencers, drum machines, control surfaces, and lighting systems to stage effects equipment – MIDI is the invisible puppet master that calls the shots in these devices.

This outstanding capability means that with some programming know-how, you can customize your equipment to react exactly how you want it to respond.

Simultaneous Control Over Multiple Devices

In addition to its ability to manipulate various types of devices, MIDI also shines in its capacity to handle multiple devices at once.

This feature becomes particularly beneficial while creating elaborate music setups involving several instruments or sound modules.

Thanks to MIDI, synchronizing and controlling all these elements becomes seamless.

Universal Standard Protocol

Another joy of using MIDI is that it provides a universal standard for many different types of devices through its meticulous coding system.

Over 128 different instrument sounds can be identified, and over 16 separate channels can be used for sending more than one stream of information at once.

Provides Clocking Information

Providing clocking information serves as another advantage point for MIDI technology.

Clocking information helps synchronize tempo between different devices (for example, syncing a drum machine with a sequencer).

This ensures all your gear stays tempo-locked, providing excellent timing consistency across your entire setup.

Control Messages Beyond Notes

Beyond mere note performance data (note-on/off), control messages make up an essential part of what makes working with MIDI so flexible and powerful.

Control messages allow real-time manipulation over parameters like volume, modulation depth, or pan position across stereo fields, adding expressiveness and dynamic range to performances.

Cons of Using MIDI

Although packed with numerous benefits, MIDI technology comes with its own set of drawbacks:

Less Common I/O Ports in Newer Devices

Newer computer systems, sound cards, and mobile and tablet devices may not have physical MIDI IN/OUT ports.

Although most manufacturers now rely on USB-MIDI or Bluetooth LE-MIDI interfaces (which perform equally well), having an option for old-style MIDI connection would be a valuable addition, especially for people with ‘vintage’ gear.

Sound Quality Can Be Inconsistent

Another downside is that the quality of MIDI instruments can sometimes leave much to be desired.

This is because MIDI data doesn’t contain any actual sounds. The sounds depend on the synthesis technology of your MIDI device – a software sampler or synthesizer that interprets and executes the instructions in the given MIDI data.

Dependence on Sound Card Quality and System Performance

The quality of the sound card, as well as the overall system performance, plays a vital role in determining the performance of MIDI devices.

As we discussed earlier, the sound you hear is generated by these synthesizers and samplers, which often require substantial resources.

Only Works With Digitally Capable Instruments

Lastly, it’s worth noting that MIDI only works with digitally capable instruments.

This means if you are an enthusiast who still holds onto beloved analog equipment that lacks digital interfacing capability, these tools might not fully integrate into a modern DAW-centric workflow.

One can understand why it is still pivotal in today’s music industry by exploring its pros.

Awareness of the cons helps you prepare better while integrating musical instruments into your setup.

Types of MIDI Equipment

There’s an entire gamut of MIDI equipment available in the market today, and it can get overwhelming when trying to decipher which one is right for you.

I’ll guide you through various types of MIDI gear and break down their functionality to facilitate a better understanding of their use:

MIDI Cables

MIDI cables essentially function to connect all your MIDI devices. These standard five-pin DIN cables connect the ‘MIDI OUT’ port on the transmitting device to the ‘MIDI IN’ port on the receiving device.

The cable allows a stream of data or instructions (in the form of MIDI messages) to pass from one MIDI device to another.

MIDI Ports

These ports are usually found in three types: ‘IN,’ ‘OUT,’ and ‘THRU.’ The ‘IN’ port allows receiving data, while the ‘OUT’ port enables data transmission.

The ‘THRU’ port re-transmits data received at the ‘IN’ port, facilitating a continuous chain of control among multiple devices.

MIDI Interfaces

Zoning into MIDI interfaces is crucial if your computer lacks a dedicated MIDI Out/In connection.

It’s a piece of hardware that effectively communicates between your computer and other devices connected via MIDI cable – whether it’s musical keyboards, sound modules, or drum machines.

External MIDI and Synthesizers

Your software instruments can also be external gear – we refer to them as hardware synthesizers or sound modules.

They can be modules specializing in specific sounds like strings drums or full-blown synthesizers that give you intricate control for sound designing.

MIDI Controllers

Now let’s dive into MIDI Controllers. They are input devices that send MIDI information into your computer, interpreting those instructions into audible sounds.

This could range from keyboard controllers that recreate the feel of a piano to pad controllers that replicate the experience of an MPC or various types of specialized controllers like MIDI guitars or wind controllers.

MIDI Chord Packs

Next up are MIDI Chord Packs. They are precious tools for composing music and learning music theory on your MIDI instrument.

This is because chord packs contain MIDI data that enables setting up a progression of chords in your music production software, thereby simplifying the composition process.

MIDI Files and The Piano Roll

MIDI files are instructions telling your software what sounds to trigger at what intervals. This data can be visualized on a Piano Roll grid, where you can create, view, and edit these instructions.

Let’s take a moment to appreciate MIDIs’ vast capabilities across multiple platforms and uses in modern-day electronic music.

From cables to interfaces and everything in between, there is an array of tools serving purposeful roles within digital music production.

Mastering these tools lets you make the most out of your musical journey using MIDI.

Ultimately, no matter what gear you choose, remember that staying creative and exploring uncharted territories makes for rewarding experiences when making music via MIDI.

Computer, MIDI Interface, and Synthesizers

If you fancy working mainly with hardware synthesizers but also need the convenience offered by modern digital technologies, this setup is ideal for you.

In this arrangement, your computer connects via a MIDI interface device to various external hardware sound modules or synthesizers.

You use your DAW to record and sequence MIDI data, which gets sent out via the MIDI interface into your external synth collection, where each device has its dedicated MIDI channel for independent operation.

Thus giving birth to an exquisite symphony in synchronization.

Hardware Sequencer, Drum Machine and Synthesizer

Stepping up onto an all-hardware playing field might seem daunting initially but believe me it’s worth every penny.

This setup typically consists of A master sequencer (like an SEQ) and a drum machine (like a Roland TR-8). Here’s how you set them up:

1. Connect the MIDI Out of the master sequencer to the MIDI In of the drum machine.
2. Then, connect your synthesizer to another channel on your sequencer.
3. That’s it. Your sequencer can send note information to your drum machine and synthesizer separately.

Each of these configurations has its unique charm, advantages, and considerations.

The choice ultimately boils down to personal preference on workflow, space availability, budget constraints, and musical objectives.

It’s pertinent to remember that MIDI is a versatile protocol that can adapt remarkably well to cater to even bespoke audio setups.
