It sounds very authentic!

I love the way this mellotron app sounds! I have a couple grips though. one. when I use midi there is no sustain with this app so if I want to put emphasis on a chord the signal it dies out right away when I change chords creating a very very dry sound. Which is actually authentic but we should have the option of it. at least that way we can integrate this app with daw sounds easier. Because otherwise it just doesn’t flow as smoothly and sound blocky in the mix. Now there is reverb which can help with that problem but ends up sound a bit muddy when I have the level of sustain I’m looking for. Which is a shame because
The sounds are beautiful and authentic. Second. The app only has 2 octaves to choose from which is fine like the original. If you have a full 49 key then this would work. But, I have a 37 key midi and when I switch octaves the keys start making sound in the middle of my keyboard which makes for some awkward playability. Other than that it sound wonderful and true. Fingerlab Please in corporate sustain in the sounds!

Potential to be the best one

It has been frustrating finding the perfect Tron app, as they all have a lot of issues. This one seems promising. The interface looks great, as are the effects, and the upcoming adsr update is something to look forward to.

Two small gripes...I have the latest version, and the battery drain problem is still there. I left my phone unplugged overnight and it was almost dead in the morning, settings said that 83 percent of battery use was from the app.

The other small gripe... Some of the Tron sounds they include are not the ones commonly used. Of course, the flute and sad strings are there, but the Tron isn't exactly known for its electric guitar samples, so I hope that in the future, some more of the popular bigger choir sounds and some more orchestra variations make it into the mix. A small gripe, but I play old school Berlin School music and those tones are vital. this certainly has the potential to be the best Tron out there.

Suggestion/wish. Ability to blend sounds, like brass and violins, so I can play Watcher of the Skies.😏 Thanks for a great app.

Pretty darn good

I like this a lot! I’ve seen and heard the original, and I’ve gotta say That this app is as good or better than other apps that represents itself to be a true copy. A true copy would present with a plethora of problems if one say, wanted to take it on the road. A true mellotron would have a pitch that varied by temperature. Moreover, it would be a surprise if the thing would have worked at all! I suppose if you tinkered long enough with this app you could tweak *all*of the sounds, making them nice and shiny... But then this app wouldn’t be able to trigger thoughts about the past and the inclination of some users to create new arrangements with tools to represent something worth keeping. In short it wouldn’t sound like a mellotron. Serious well done folks, I liked it enough to pay for it:)
