GREAT synth.. now w/ MIDI input :)

This INCREDIBLE synth has been updated to support MIDI input 😎👍 That’s the power-up it needed to transform it into a most useful mobile music production tool. Time to dive in and explore the sonic landscape 😃📱🎹🎶

Original Review:
The Europa synth sounds fantastic on my iPhone!! It’s great that I can use it in AudioBus and that it supports Ableton Link. I also appreciate the ability to demo the advanced synth controls and settings, which work great and give a lot of tonal flexibility when it comes to sound design. However, I cannot bring myself to spend $9.99 on this fabulous synth’s advanced features because it does not support MIDI input. That is a must-have feature for me... and probably a lot of other iOS musicians, as well. Adding support for wired, network, and bluetooth MIDI input would be ideal for handling different live and recording workflows in iOS. Also being able to save user-created presets within the Sound Packs -> Select Sound part of the app would be very useful. Lastly, adding AUV3 support would allow iOS musicians to run multiple instance of the synth in a given workflow, making the synth a much more versatile tool for mobile music development. Please consider making these updates to turn this great synth into a powerhouse. IMHO, adding these features would elevate this synth to a 5 Star app.


Reason Compact should be a controller for Reason

Oh Propellerhead, what are you doing. No no no. I applaud you for giving up on Figure (although that app did have the simplicity down which is one of the things this lacks) but you’ve got it all wrong with this app. I’m not sure if the tech exists for this yet, but Reason Compact should simply be an instrument for Reason on a computer. You should be able to use it to make expressive sounds / performances that would be hard to do on the computer. Keep it extremely simple at first. You’ll perform on the computer and just use the app for tweaking sounds, recording automation etc.

The problem with these mobile music apps is that you end up looping what you’re making over and over and over again, and you just get sick of listening to it very quickly. I would never, in a million years, make anything I could release, with this app.

It needs to be a useable, indispensable instrument for Reason first. Maybe much later it can turn into a sequencer.

One more thing. I used the app long enough to become annoyed by having to keep tapping Demo every time I swiped to another page of the controls. Let me demo the thing or not. Don’t keep reminding me I’m using a demo. Doesn’t make me want to buy it.
