Audio Damage, Inc. released Pumphouse, an AUv3 compressor with faux-sidechaining.
For those of you unfamiliar with the concept of sidechain compression, it is the source of that "breathing" quality on a lot of EDM synths. You take one audio signal and use it as a controller to affect the compression on a second. The most typical scenario would be to take your kick drum and use that to cutout your bass. So when the kick hits it kills the bass for a fraction of a second, and as the compressor releases it gives the bass a nice bloom. The effect was endemic to EDM 5 years ago, but it is still a nice effect when used tastefully.
Rather than deal with routing audio all over to do a real sidechain compressor, Pumphouse includes a step-sequencer to achieve the same effect... let's be honest, you just need it to hit on the 1s in a 4/4 anyhow.
Pumphouse iTunes Description:What do you do when you need the sidechain pumping effect in an iOS DAW that doesn't have sidechaining? Pumphouse to the rescue!
Pumphouse is a simple and excellent compressor (taken straight from our RoughRider 2 codebase) coupled with a step sequencer driving an envelope generator. In this manner, you can sidechain-compress your pads or bassline against a 1-measure pattern, no other inputs required.
With an easy-to-understand interface, Pumphouse is a quick method for getting That Sound.
Pumphouse requires transport information to work. Please note that some iOS AUv3 hosts do not have a transport. (At this time, Auria Pro that we're aware of.) There is an Inter-App Audio version supplied, but it also requires transport info.
We have tested and approve the AUv3 with AudioBus 3, Cubasis, GarageBand, AUM, ModStep, Zmors Modular, and Beatmaker 3.
