This is the official and the only Mellotron app with sounds from the original library. It contains 18 sounds from both the Mellotron and Chamberlin library, emulations of the characteristics of different Mellotron and Chamberlin models plus a reverb.

This instrument supports Core Midi, Audiobus output (Audiobus 2 & 3) and midi input (Audiobus 3 only).

The Mellotron is a keyboard instrument that uses magnetic tape to play back recordings where each key has one tape. When you press a key, the tape starts and the corresponding pre-recorded note or sound is played back. When you release the key the tape is quickly rewound back to the start point.

Invented in 1950 by the American, Harry Chamberlin, it became popular among recording musicians when it was manufactured in the UK as the "Mellotron" (a hyphenation of "melody-electronics").

Before the introduction of digital samplers, this was the only way for keyboardists to play real instrument sounds like strings, flutes, rhythm ensembles and sound effects from a keyboard instrument.

Few people know about Mellotrons and Chamberlins, but almost everybody has heard the sounds they produce. Among the most well-known tracks are BeatIes "Strawberry Fields Forewer" (flute), Moody Blues "Nights in White Satin" (3 violins), Oasis "Wonderwall" (cello), Radiohead "Exit Music for a Film" (choir), Lana del Rey "Ride" (Chamberlin flute).

We at have collected, conserved and improved Mellotrons since 1989, and have been making tape Mellotrons since 1999 (the MkVI and MkVII).

Gets the job done and then some

Having a portable Tron is something I couldn’t resist. I’ve been experimenting with it in conjunction with some small synths and the results are interesting and effective. Definitely plan on going further with it.

*If I had one thing I wish was in there it would perhaps be a set-up bank. Opening it up to the same three voices can get a little tiresome, especially when I need to re -figure out which combination I was liking in a previous session.

Other than that though, simple and intuitive instrument with some unexpected quirks (shifting and double tapping the knobs WHILE playing has made some really cool sounds).

Amazing App

Very very great! Sound is great and is fun to play with. However, I would like to ask why it sounds either out of tune or a bit late for a quick moment when you press a note. For example, whenever I use the 8 Voice Choir, the voices sound very out of tune before finally getting in place. I hope that could be fixed. But otherwise, I immensely enjoy this app. 10/10!

Developer Response ,

Hi! Thanks for the review. The Mellotron app is using sounds from the original Mellotron/Chamberlin sound tapes. The reason why you are experiencing some delay on some sounds and that some sounds are slightly out-of-tune are simply because that is how the original ones sounded! /Mellotron Team

Great update!! Excellent app

Everything seems great!! Thanks for the hard work!!!!

Feature request: background audio. Last state saving when closing. Or even presets so when you close you can instantly have your last sound back.

( background audio gives you the ability to turn off the iOS screen and allow the app to still play )

Developer Response ,

Good ideas! But right now the hardware Mellotrons need some love. A bit unclear what you mean with ”background audio”? You can play along to another app that is platina music, and with Audiobus you can play while the Mellotron app is in the background. /Mellotron Team
