It is essential to select a proper MIDI cable when connecting MIDI devices. You’re wiring a MIDI keyboard to your computer or linking up any number of instruments with each other, then the quality and kind of cable are undoubtedly crucial because the link will be worse. In this post, we are breaking down the types of MIDI cables, what each one does, and how you should use them for your setup.
What Is MIDI?
MIDI (Musical Instrument Digital Interface) is a protocol that allows electronic musical instruments to communicate with each other. Unlike audio signals, MIDI transmits data such as note information, pitch and control changes. This transmission of digital data requires specialized cables, not audio cables.
Types of MIDI Cables
There are several types of MIDI cables for different purposes. Let’s take a look at the most common ones:
Traditional 5-Pin MIDI Cables
- What It Is: A traditional 5-pin MIDI cable connects instruments such as keyboards, synthesizers, and drum machines.
- Why Use It: It transmits MIDI data between devices via a 5-pin connector, but only three pins are used for communication.
- Example: You can use this cable to connect a MIDI keyboard to a sound module or computer.
USB to MIDI Cables
- What It Is: These cables convert MIDI data into USB signals, allowing you to connect MIDI devices to your computer.
- Why Use It: This is a simple and effective solution for directly connecting a MIDI keyboard or controller to a DAW (Digital Audio Workstation).
- Example: Use a USB-A to MIDI cable to connect a MIDI keyboard to a laptop for music production.
USB MIDI Interface Cables
- What It Is: These cables connect multiple MIDI devices to your computer via a USB port.
- Why Use It: If you have multiple MIDI devices, this interface provides a simple and convenient solution for managing multiple connections.
- Example: The M-Audio Uno USB MIDI interface connects MIDI keyboards and controllers to your DAW.
MIDI to USB Cables
- What It Is: This cable connects a MIDI device directly to your computer’s USB port, making it easier to connect to your DAW.
- Why Use It: The MIDI to USB cable is for direct setups using a MIDI device.
- Example: This cable is perfect if you have a MIDI keyboard and want to connect it to your computer for music production.
TRS to MIDI Cables
- What It Is: These cables transmit MIDI data using a 1/4-inch TRS (Tip-Ring-Sleeve) jack.
- Why Use? They’re great for connecting pedals or MIDI devices in your guitar setup.
- Example: A Rockboard flat TRS to MIDI cable connects a guitar pedalboard to a MIDI controller.
How Does MIDI Work?
MIDI (Musical Instrument Digital Interface) is a standard for sharing information between devices, such as note on/off messages and velocity/control changes. Devices communicate through ports such as MIDI in and OUT. The MIDI protocol allows you to play multiple instruments on a single keyboard or interface.
Choosing the Right MIDI Cable
The MIDI cable you need depends on your setup and how you plan to connect your device. Here’s how to make your choice easier:
For MIDI Keyboard to Computer
Choose the USB to MIDI cable to connect a MIDI keyboard to your computer. This is an easy way to send MIDs to your music software.
For MIDI Controller to Sound Module
The 5-pin MIDI cable connects sound modules or external MIDI controllers. This ensures a stable connection and safer data transfer.
For Multiple MIDI Devices
It’s best to use a USB-to-MIDI cable when connecting multiple MIDI devices. This cable allows you to manage multiple connections through a single USB port.
For Pedalboard Setups
When working with pedalboards, consider using a TRS to MIDI cable. These compact cables help minimize clutter while providing the MIDI functionality you need.
FAQs
What’s the difference between USB to MIDI and MIDI to USB cables?
- USB to MIDI cables connect a USB device (like a computer) to a MIDI device.
- MIDI to USB cables connect a MIDI device to a USB port on your computer.
What is an optically isolated MIDI port?
An optically isolated USB port isolates the signal from electrical noise and ground loops, helping to maintain its shape. This is handy for professionals where signal clarity is essential.
Which MIDI cable is best for a keyboard?
When connecting a keyboard to a computer, a USB MIDI cable or a 5-pin MIDI cable is ideal. It depends on whether you’re using a direct connection or an interface.
Where can I buy MIDI cables?
You can purchase MIDI cables at stores selling music equipment and online retailers like Walmart, Best Buy, or music equipment websites.
Do I need an adapter for my MIDI setup?
If your device has separate ports, you may need an adapter. For example, a MIDI adapter cable allows a 5-pin interface to pass through a USB port.
Conclusion
Choosing the right MIDI cable for your setup can ensure that all your hardware is working well. Whether you have a keyboard connected to your computer or multiple devices connected, MIDI cables can help you communicate between your application and your instruments.
