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.

Tape Pro is a multi-fx tape emulation AUv3 plugin and app that introduces warmth, frequency shaping, modulation, noise and delay. Whether you want to accurately replicate a microcassette tape running at 1.2cm/s, or you want to drive a mastering grade tape machine with strange distortion shapes into a high feedback delay engine, Tape Pro is the plugin for the job. Saturation The saturation module is the first part of the signal chain within Tape Pro. It’s very flexible as it isn’t restricted to the traditional sound of tape and can be used to tune into your desired distortion sound. The module has 5 user parameters: Type, Drive, Asymmetry, Hysteresis and Remanence. The types of saturation on offer are: Tape, Digital, Rectify, Half-Rectify, Sine & Smooth. Response The response module within Tape Pro models the dynamic frequency response of tape. This can bring warmth, presence, or even jarring qualities to your audio - this is entirely subjective of course! The module has 3 user parameters: Type, Low Pass & High Loss. Tape Pro includes the following impulse responses: Cassette Type 1, Cassette Type 2, Cassette Type 4, Worn Copi-Delay, New Copi-Delay, Mod Copi-Delay, Master SA812, Master TM15, Microcassette 1.2cm/s, Microcassette 2.4cm/s, Semi-Pro RB77 7.5ips & Semi-Pro RB77 15ips. Tape Pro also includes Minimum Phase (MP) versions of the IRs listed above (not including the copi-delay versions). If you are using Tape Pro in parallel, on a bus or on a send, we recommend that a minimum phase IR is used. (For more information on this please see the explanation in the manual available from our website). Noise The Noise module applies real, sampled tape noises to the signal chain. The module has 4 user parameters: Type, Pre/Post Delay, Gain & Crosstalk. The noises included are the same as listed above in the response module. Wow & Flutter The Wow and Flutter module emulates the natural irregularities in the physical medium of tape. Wow recreates the low speed fluctuations of tape speed, while Flutter recreates the high speed fluctuations. The modules have 10 parameters in total. Wow: Depth, Sync, Rate, Mod, Sync x2 and Mod Rate. Flutter: Depth, Rate, Mod, Mod Rate. Delay The Delay module is an emulation of an analogue tape delay machine. The module has 11 user parameters: Dry, Wet, Time L, Time R, Feedback L, Feedback R, Portamento, Enable, Initial, Sync and Link. Tape Pro is both a stand-alone application as well as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as GarageBand.
