The Electro-Harmonix Mini-Synthesizer comes to iOS

Electro-Harmonix has relaunched its 1980s cult classic, the Mini-Synthesizer, for iPhone and iPad.

The app comes with 22 presets and the ability to store, what EHX promises, "an almost unlimited number" of user preset programs.

The Mini-Synthesizer also includes a virtual MIDI input, aftertouch (iPhone 6s and 6s Plus), an enhanced effects section plus Audiobus and Inter-App audio capabilities.

The synth is available from the App store now at £3.99 for the iPad version and £2.29 for the iPhone edition. From September 2016, Mini-Synth will be available on Android. For more information check out the EHX website.

Video Producer & Reviews Editor

I take care of the reviews on MusicRadar and Future Music magazine, though can sometimes be spotted in front of a camera talking little sense in the presence of real musicians. For the past 30 years, I have been unable to decide on which instrument to master, so haven't bothered. Currently, a lover of all things high-gain in the guitar stakes and never one to resist churning out sub-standard funky breaks, the likes of which you'll never hear.
