Mellotronics Streetlytron Pro promises the most authentic Mellotron emulation on iOS

The Mellotronics Streetlytron Pro from Omenie has been developed with Streetly, the original creators of the Mellotron, and as such, is touted as being the “most authentic Mellotronics experience for your iPhone and iPad.”

The iOS app involves the use of Streetly’s original production master tapes, which also come with its $8k M4000 model, as part of the 90 tapes that are included with Streetlytron Pro (see the complete voice list below).

Every control is accessible via MIDI, or you can perform via the on-screen three-octave keyboard. The Streetlytron features a “gorgeous, silky-smooth, ultra-musical reverb unit”, that promises to generate “immense spaces”. You’re also afforded eight programmable preset slots, voice selection, detune, pitch and tone controls.

Virtual MIDI, AudioBus and Inter-App Audio are all supported in Mellotronics Streetlytron Pro, which is available on the App Store now for $24.99/£23.99.

There are no in-app purchases, but this does mean you will need 1.7GB free on your chosen device for the installation.

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.
