Mellotronics Streetlytron Pro : the most authentic Mellotronics experience for your iPhone and iPad.

Brought to you in partnership with Streetly Electronics, the inventors of the mellotron, Streetlytron includes a massive collection of 90 tapes, with 65 drawn from Streetly's Production Masters - exactly the same tapes that ship with their $8,000 M4000 unit. Completing the sample sets are our own very popular 'Caitlin Downie Soprano' and 'Clare Lindley Violin' collection, to offer a huge, rich selection of choral and string textures for your mixes.

Playable with the on-screen 3 octave keyboard or by an attached MIDI controller, Streetlytron Pro 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, AudioBus and Inter-App Audio are supported.

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

All voices are available in original form, straight from Streetly Electronics Production Tape library - unlooped 8 second samples, with a unique sample for every key of the 35 note range. To offer more performance flexibility the 'LOOP' button may be engaged, which process the samples to offer seamless looping. Some voices have decay tails - e.g pianos, harpsichord, staccato voices - and these are left unlooped. Streetlytron Pro Edition uses an advanced cubic spline interpolator, to delivery premium sonic quality when pitch bending or retuning.

What’s New

Version 1.4

One minor update. Two settings have been added to give you absolute control over 48kHz / 44.1kHz operation. If you have a new 48kHz device and the pitch of the audio is consistently off you can override our algorithm and force an internal synthesis rate of 48kHz. Do this in Settings by setting both 'Force Synthesis Rate' to ON and setting 'Synthesize 48kHz' to ON. Synthesis can be similarly forced to 44.1kHz by by setting 'Force Synthesis Rate' to ON and setting 'Synthesize 48kHz' to OFF. If Force Synthesis Rate is off our internal algorthm will run to try to determine what frequency is best for your hardware and environment.

Excellent sound.

Sounds fantastic, the fidelity to the sound is clearly higher than the previous version of this app (which as not bad got an app). But this, this is road-worthy, for sure. The midi tweak-ability is outstanding. The interface is nicer too. My only tweak would be to have the ABC blend knob be done in an xy pad so one could blend all three voices, though maybe it’s too processor intensive. Good job!

So, i bought this sight unseen as i love the previous version, the M3000hd. But this new app does not sound as good. There is a high frequency artifact that I’m hearing, kind of like a bad low bit rate mp3. This sonic problem isn’t present in the M3000. I’m hoping they can update this with a fix soon. I’ll add more stars to this review if that can happen.

Developer Response ,

Give it another listen - you may simply be hearing the higher sample rate of these recordings which is allowing more of the tape hiss on the original recordings to break through. M3000 used 22.05kHz samples, this series uses 33.075kHz. The app is genuinely very faithful to the Streetly tapes, which are Production Masters from their $8,000 M4000 machines. If you still think there is a genuine problem, email us, if we can get details of your device and OS p, and can get sound samples from your device, maybe we can get to the bottom of what you’re hearing, and also get you onto the beta program to give you early access to developments.

The Best Gets Better (and will keep getting even better)

I am a Mellotron fanatic. It is my absolute favorite instrument after guitar. I’ve owned a ton of Mellotron variants since I can’t afford the real one. I started with Mike Pinder’s AKAI library, I’ve owned a Nord Stage with their Mellotron sample library. Two variations of the Memotron at different times. GMedia’s Mellotron original and Pro version for my Mac with all the add on libraries. And I’ve owned this developers iPad apps with his libraries since release. I’ve been so excited for this mostly for the incoming AUv3, but also the promised sonic improvements and it does not disappoint. There is so much more there in this version and it still has all that lo-fi Mellotron magic we love. With the tone control, 1/2 speed, optional MK2 EQ preamp and cabinet modeling you have so much variation in sound available for each tape set. Want it more aggressive with some added mid-range bite, turn on that EQ, mellowed out just turn it off and turn that tone known left. This app holds its own against everything I own and have owned and it’s so usable for any studio or live application. To have this in my iPad is just ridiculous. AuV3 will make this the perfect app and its already a go to for me in less than a week. The developer has also already added two new tape banks in the first updates and is promising more in the future that will get us from (now 65) to almost 100 with no extra costs! Talk about a great deal. Thanks for the hard work and making my “perfect app” for iPad music making.
