Welcome to the party

This is a really good app. I am using it for electronic/ techno type music and is truly doing the business. I prefer to spend more time on sculpting the sounds and using effects as opposed to finding the actual note arrangement- so this fits in perfectly.
It is straightforward to use and comes with a manual should you need it.
It is well designed and laid out for easy access. It is uncluttered yet contains some highly creative features
The developers are responsive to communication and are also currently active on the Audiobus Forum. There are future developments promised though I’m very happy with it the way it is.

AudioBus....Can not control another iOS synth...

I can not for the life of me get this to control anything with AudioBus 3. Some clues on the developer’s site would be useful. It seems like it might be really useful, but I can’t do anything with it. Please fix this if it’s a bug. The Audiomodern website has no support pages for this app that I am able to find which make it very frustrating. I can’t find a manual either.... so no clues to go on there either.... HELP... it’s an interesting looking app but with no visible place to get support other than a form to fill out on the website....

Hello, please contact us at As for the manual we will include it under 'settings' it in the next update on Riffer and we have updated the website FAQ as well.

Really nice idea

Mostly well executed but actually connecting it to another midi app is something of an ordeal. As noted by another reviewer, the controls when trying to set up the midi link are very small, and I’ve only found one other app that it’s able to control. When these issues are sorted though, I imagine I’ll use this quite a lot.

Thanks for the feedback, we are working on fixing these issues with the next update,
