The Streetlytron '63 Edition : genuine Mellotronics for your iPhone and iPad.

Brought to you in partnership with Streetly Electronics, the inventors of the mellotron, Streetlytron includes a massive collection of 63* tapes from Streetly's Production Masters - exactly the same tapes that ship with their $8,000 M4000 unit.

Playable with the on-screen 3 octave keyboard or by an attached MIDI controller, Streetlytron exposes every internal control to MIDI, allowing performance and recording without ever needing to touch your device. A gorgeous, silky-smooth, ultra-musical reverb unit generates immense spaces, and 8 programmable preset slots set you up for one-touch performance. Totally playable and totally inspiring, for everything from classic psychedelic, vintage progressive, modern chamber pop or avant-garde dance sounds.

Virtual MIDI and AudioBus, with Inter-App Audio support provided by AudioBus.

No In-App Purchases, no hidden extra costs. Pay once, never pay again.

To keep this remarkable app as small as possible, the in-app samples are recorded at minor third intervals, and most in-app samples are looped for continuous play, with a loop duration of 5 seconds. This results in almost 5x reduction in app size**, yet has virtually no audible difference between this '63 Edition and the top-of-the-range Streetlytron Pro Edition. Sample replay within the app uses an advanced cubic spline interpolator, to delivery premium sonic quality.

Sounds beautiful. Variety of great sounds.

The functionality available in the app is quite intuitive, giving decent life and variations to the sounds. Some nice quality of life things too, like being able to use notes to quickly switch presets.

I bought this with the expectation that AUV3 was on its way in the near future. So far it is not here. Will change my rating to 5 stars once that is added.

Bliss at last!!!!!

I’m old now, but all my life starting with the late 60’s I’ve dreamed of having a Mellotron. Not only was the price prohibitive, I’d heard there were issues with tape life and such. I couldn’t believe my ears with the 63’ collection. Total goosebumps! Surprisingly small memory footprint. I thank the developers for making this old hippie’s dream a reality! I can’t wait for my Bluetooth midi adapter to arrive so I can use an actual keyboard. One of the first things I did was phone a friend and play the intro to Court of the Crimson King. Now if I could find a calliope track...hint, hint!

The sound quality is amazing, you won’t be disappointed!

If you lived in, or enjoy the classic sounds of the late 60’s, this Mellotron is what you want. Just a joy to use, and has all the original sounds faithfully reproduced since they came from the original instrument tapes. Interface is well laid out, and maps nicely to midi controls on keyboard. I would request that an update would support Bluetooth MIDI, so that my knobs and pads Akai wireless controller could be used. Thanks!
