Established in 1980, Alesis was founded on innovative semi-conductor chip technology and award winning industrial designs that allowed entry level musicians and recording artists to afford professional studio recording products that were never affordable before. With high "bang for the buck" value, Alesis introduced the world's first professional 16 bit effects processor under $1000, the Midiverb.  Following on the heels of the Midiverb, Alesis progressed into studio quality drum machines (HR-16 and SR-16) as well as synthesizers, studio monitors and mixing consoles.

If there's one secret to our enduring brand and the passion it ignites in musicians, producers and engineers, it's that we deliver these experiences, rather than merely a collection of products and services. We"re dedicated to inspiring musical creativity and developing musical experiences for all of our stakeholders – customers, employees, partners, suppliers, and the musical community at large. That's what sets Alesis apart from the crowd and why our brand continues to be on the leading edge of professional audio and music technology.

While our products range from keyboards, synthesizers, hard disk recorders, iPod recording and playback devices, electronic drums, mixers, signal processors, effects units, amplifiers and speakers one thing remains consistent; our passion for inspiring musical creativity and innovation through new technology.
