The use of an online sequencer can be a valuable tool in music production. Over the last few decades, the internet has transformed the way music is made. Gone are the days when music could only be made using physical instruments and musical equipment. 

The introduction of online MIDI sequencers gave artists access to a range of electronic instruments and musical effects. Programmers and developers have spent many hours creating sleek and easy-to-use web-based music programs that can do everything from composing to mastering. In this article, we will take a look at what online sequencers are, and provide our top picks for the best ones!

What is an Online Sequencer?

An online sequencer is a piece of software based or an application that allows artists and musicians to perform a range of music production tasks, such as recording and editing music. Music sequencers perform these tasks by processing notes and other types of music data usually through MIDI files. 

Sequencers first came out as standalone pieces of equipment such as a MIDI keyboard or MIDI controller drum machine that recorded the events related to a musical performance.

Hardware sequencers used for sound recording or DAWs were then introduced into the musical field. Today, making music is now easier as possible, as there are many sequencer tools and packages available online. Many sequencers that exist via the web are completely free to use!
