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.
