### 5/5 — You should get this

*2026-06-14*

If you make music on garage band and you like prog rock then this is the app for you even if you dont have the premium the 3 presets you get are cool and you can have 2 tape tracks play at the same time

### 3/5 — Not many presets for the price

*2026-06-05, version 6.3.3*

See title for review

### 5/5 — Thank You!

*2026-05-30*

iPhone Air update has corrected all issues discussed.  Fingerlab also took the time to contact me!  Thank You!

### 2/5 — Too hard to miss black keys

*2026-04-04*

It’s impossible to hit white keys without accidentally hitting the black keys in between. You don’t have to touch over an actual black key, the app treats everything chromatically. If you try to touch way down at the end of the key to avoid the black key, the app thinks you’re trying to close it, so the whole keyboard starts moving/trying to close the app. Unusable without some sort or other controller, which I don’t have. USELESS.

### 1/5 — Love the app but update…

*2026-02-03*

I love this app and have been using it for years. However, with the recent update AUM no longer recognizes it in any of my older projects, essentially telling me it isn’t installed even when it is.  Is there a way for this app to be updated so that wouldn’t happen, as this has now damaged dozens of hours of work?

### 4/5 — It’s amazing

*2025-12-25*

Except for the fact that I need to pay to get strings, but that aside it’s a really warm and nice sound. Ripped out of the 60s.

### 3/5 — Can't turn off app?

*2025-11-05, version 6.1.2*

Generic keyboard app with no off button. I have to restart my iPhone to shut it down! Not cool!

### 2/5 — Sounds great, but midi not working

*2025-03-07, version 6.1.2*

Title tells the tale. My iPad Pro has many midi inputs (recognized by apps such as Numa Player), but this mellotron app does not see them. Can’t use it if it fails to see the available midi inputs.

### 5/5 — Awesome.

*2025-02-23*

That’s all. Good night

### 5/5 — Simulazione ben fatta.

*2025-02-13, version 6.1.2*

La App è fatta bene, molto semplice e intuitiva. I suoni sono perfetti, con quel sapore un po’ antico. Una volta sbloccata la versione completa - il prezzo è più che ragionevole - c’è anche la possibilità di un minimo di editing dei suoni attraverso un  inviluppo ADSR e una serie di riverberi. L’unica pecca, ma è un parere soggettivo, è l’estensione della tastiera a circa tre ottave, che poi era effettivamente l’estensione dello strumento originale. 
Con un semplice cavo midi si può collegare alla tastiera e il Mellotron è con voi. Ottimo lavoro.
