This is an AUv3 compatible stereo compressor plugin which is intended for use inside your favourite DAW/HOST such as AUM, Cubasis, Auria, Meteor, AUM or GarageBand etc. So lets start by answering the question what is side chaining?  Side chaining is a technique used in a lot of modern dance music which involves using the volume level of one sound source to control another. You can hear plenty of examples of this in modern Trance/Dubstep music where sound engineers use the impact of a bass drum to duck a sustained string sound, creating space in the mix. This can be heard as a rythmic pumping sound which gives your music drive and energy. This compressor is quite unique since it was designed to get around the limitations of AUv3 plugins on iOS and the lack of multi-audio routing inside DAW apps. Until recently it wasn't possible to do true side chaining using AUv3, but now AUM has recently integrated support for multiple inputs and outputs per AUv3 plugin, it opens up a whole new world of possibilities. This is great for AUM users, but this still leaves users of other DAW's in the dark. This is where this app has you covered as it provides a method of sudo side-chaining by allowing you to attach two instances of this plugin to multiple sources and route audio between them to achieve a sudo sidechain. This works by ensuring two instances of the plugin are loaded as insert effects, one being the MASTER and the other a SLAVE. The slave sends audio to the master by means of one of 3 available busses. True side chaining can be achieved in AUM. Simple set the SideChain Mode to 'Normal' and install an instance of the plugin on the channel you want to control. Then using the new 'Multiple Audio Unit Instances' option in AUM you can add a redirection of the controlling source to send to the same bus the plugin is listening to. It's that simple. In this case you need to set both instances to either Bus 2 or 3, since Bus 1 is the original audio. Features: ○ Standard Compressor features. ○ Real calibrated VU and reduction meters ○ Real-time visual graphing of parameters. ○ Real sidechain in AUM. ○ Sudo side chain using MASTER and SLAVE for others. ○ 3 available busses. ○ Mono / Stereo modes. ○ Integrated help.

AUM can send MIDI clock, but it can't follow one. ClockBridge closes that gap. Load ClockBridge in AUM as a MIDI processor, route your hardware's MIDI into it and turn on Link. Your groovebox or sequencer now sets the tempo, and pressing play on it starts AUM straight away, on the hardware's downbeat. Stop stops it. It's one button. The ring tells you what's happening: grey while it waits for clock, yellow once it has locked on, red if the clock goes away. Pull the cable mid-song and the tempo holds and the music keeps going. • Follows tempo changes as you turn the knob • Starts AUM on the hardware's downbeat instead of at the next bar • Steady timing even when the host delivers clock in audio-buffer steps • Timing offset in milliseconds, to line up with your hardware's latency • Sync can be mapped to a hardware button in the host • Light enough to load in every project ClockBridge uses Ableton Link, so the tempo is shared with every Link-enabled app on your iPad and your local network.
