Having a USB connection provides crucial benefits for modern musicians and producers, primarily related to connectivity and workflow. USB enables a direct link between the synthesizer and a computer, making it possible to transmit MIDI data seamlessly without relying on traditional 5-pin MIDI cables. This connection allows the synth to function as a MIDI controller, sending and receiving MIDI signals to and from a DAW (Digital Audio Workstation). As a result, musicians can easily sequence and record their synth performances, automate parameters, or even use the synth to control virtual instruments within the DAW. This streamlined setup saves time and reduces the amount of cabling and interfaces required, creating a more efficient studio or performance environment.

In addition to MIDI capabilities, USB ports on synthesizers often support data transfer and software updates. This means users can back up and restore patches, download new firmware updates to add features or improvements and manage their sounds with dedicated software. For some portable or compact synths, USB connections also offer a convenient power source, allowing the synth to draw power directly from a computer or USB battery pack. This combination of data management, connectivity, and power makes USB-equipped synthesizers a versatile and practical choice for musicians seeking flexibility and ease of use in their setups.
