Propellerhead brings their incredible Reason software to iPhone and iPad, offering a powerful synthesizer in an accessible package. Create, record, and share beautiful melodies with automatic arpeggios, effects, and an expansive collection of sounds to get exactly what you’re looking for. The best part? If you make a mistake, you can correct and modify your work in the note grid!

Prerelease software? I’m Confused.

First of all, this isn’t “Reason” or anything like it. This is just the Europa Synth from Reason dumbed down for iPhone, and stripped of features you will have to IAP. No idea why they chose to call it “Reason Compact”. When I saw “Reason Compact” I got super excited, then realized how misleading the name was and was unfortunately disappointed.

On the plus side it sounds excellent. Of course. Interface is clean and well designed.

Now my gripes.

This app is dumbed down, and all geared up for in app purchases. Those features are in demo mode and marked as “unavailable” with no explanation. Most of the panels like envelope, unison, effects, as well as the sound expansion packs are also unavailable with no explanation. You’re locked into major or minor scales, which is completely insane. I can map a custom envelope to a filter but I can’t play a full keyboard. What??? You also sadly cannot save variations of your song. It just auto saves over what you’re working on or you need to start from scratch.

The sound of the Europa synth is the selling point, but that aside I have a hard time understanding where this product fits into the iOS synth/DAW ecosystem, when features will become unlocked, and why the misleading name.

Super Unique! Nicely done 👍


Great sounds, love the UI design
