Mellowsound is an emulation of a legendary instrument, a keyboard sampler from the 60s used by many famous artists like the Beatles, David Bowie, Radiohead and many others, this mythic instrument is called The Mellotron. You probably never heard his name but the melodies created with it are mythical.

As we have the chance to own a Mellotron M400, we wanted to share with you this unique sound, so we sampled all the notes from our beloved Mellotron, one by one, for all the instruments tapes.
With Mellowsound, you will be able to play Mellotron on your Mac with professional audio quality (16bit/44Khz), as a standalone app, or in your favorite DAW as an Audio Unit.

In the same spirit, we designed a smooth and photo-realistic user-interface as an homage to our dear Mellotron.

-18 instruments (including Sad Strings, Electric guitar, Vibraphone and many more…)
-Classical Mellotron settings: Volume, Tone & Pitch
-3 FX: Tremolo, Delay & Reverb
-Live Recording & Metronome
-Midi support
-Audio Unit support
-Fullscreen support

Soon coming: more Fx & ADSR envelope control!

We hope you’ll enjoy it!

Stay tuned!

What’s New

Version 2.0

This update brings a new feature to Mellowsound: an ADSR envelope editor for the two instruments layer.
Envelope is a really important feature as a simple change, attack or release for example, will make all instruments sound very different.

Stay tuned!

Is there a fix in our near future?

I love this app in all its awesome glory, except that it wont work properly in garage band. When I try to open and use it, only the trial version opens and tells me i need ann in app purchase to use all the features. I have the full version and have paid for it on 3 seperate devices! When I open the full version I end up with only the trial version with limited capabilities recording into garageband? The full version does not override the trial version and I cant seem to delete the trial either. I've read through the guide but find no answers, please help or will there be a patch for this issue anytime soon? I'd love to add a final star in my ratings once I can record with full the Mellowsound midi features in Garageband!

App doesn't compile AU plugin to use in other DAWs

While the samples in this plugin are fantastic, there is no AU plugin that is created or installed to use in other DAWs. It seems like support was only created for Garageband (.appex file in the package contents) and nothing else. I believe the .appex is supposed to compile an AU .component usable in other DAWs when the app is opened for the first time, but this isn't the case.

I've sent an email to them, and will be leaving this low review to inform the developers of this issue. Hopefully it can be fixed in the future.
