Electro-Harmonix’s new Mini Synthesizer app

Popular guitar pedal manufacturers Electro-Harmonix have come out with a new fully fleshed out synthesizer for iPad and iPhone.

Since 1968 Electro-Harmonix have been pioneers in the world of instruments and effects in music. Keeping with the times Electro-Harmonix are releasing a digital version of their cult-classic 1980 analog synth as an app for mobile devices.

The Mini-Synthesizer app comes with 22 presets and the ability to store an almost unlimited number of user preset programs. The easy-to-use Electro-Harmonix Mini Synthesizer app is loaded with great sounds and features and is sure to appeal to serious musicians and non-musicians alike.

Electro-Harmonix president and founder, Mike Matthews said: “Fans of vintage synths will appreciate the app’s ability to re-create the original’s warm analog sounds and deep funky bass. But because it’s so affordable and user friendly, parents, educators, and non-musicians will love it too.”
