Great Compressor, AUv3 Please!

I was excited to see there was an update but a little sad to see it didn’t turnout to be AUv3... I love this plug in but would love it even more if I could use it more often.

Developer Response ,

This is the old IAA effect app, released long before AUv3 even existed. An AUv3 version is coming soon!

Kills Battery..Great Otherwise

This is a nicely programmed piece of software, but it suffers from one large setback. First the positives; great user interface. This makes the product easy to use which is important to a creative workflow. Sound quality is top notch and the ability to integrate with others apps is all there. Side chaining is a godsend. The big negative here is that this app will continue running in the background and help drain your battery quickly. This happens even with background app refresh disabled, force quitting and rebooting. Would have been at least a 4 star otherwise.

These still come in handy

FLSM is not on the AU band wagon yet but I really like it. The IAA versions of the Kymatica fx are a perfect fit. They are stable, always work as expected and sound great.
