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).

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

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

Great app but doesn't sound very realistic compared to a real mellotron. Wish it had a couple more voices (organs, piano, reed instruments) and that "pop" sound whenever you play a note like a real mellotron like the Super Manetron app does.

Also in regards to the audio distortion - it doesn't occur when you play through a Bluetooth output.

I LOVE IT!!!!!

So far, this is the BEST Mellotron App I have ever tried out! I think this instrument should have MORE Mellotron & Chamberlin Samples such as the Chamberlin Harp Solo, Harp 7th Arpeggio, and Harp Rolls, More Mellotron Moving Strings Sounds, Mellotron Artist Sounds such as the Yes 2 Violins, Yes Arpeggio Violins, Roxy Music I & II Sounds, More Mellotron Rhythm & Fills, etc.

Once a miracle APP


Dear ALL
Like you, I’m hopeful that the current bug that causes distortion on the audio will soon go away.
Prior to the distortion artefact, this has been an amazing app!
Patiently waiting for the bug to go away!
