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.

It's broken. Dusty. Hazy. But from those imperfections, something beautiful emerges. Dark Park is a generator of cinematic pads and drones, sounds that feel like they're decaying, collapsing, breathing. It's designed for exploration and instant inspiration. When you enter the park, you're given a navigation device. Tap "Scan", and the world beneath the surface generates a new synth patch. Every result is guided by musical constraints, so even the broken ones remain beautiful. If you find a sound you like, you can save it as a preset. There are two paths through the park. Take the Clear Path for delicate, melancholic textures. Or wander down the Obscured Path, and discover sounds that ache. The interface gives you a curated set of controls: Fog. Halation. Sodium. Spray. Pressure. And of course, the familiar ADSR controls to shape the sound further. Play Dark Park as a standalone instrument, or combine it with your favourite effects to create dark ambient music or arthouse cinematic scores. Feature list: - Cinematic synth engine designed for dark ambient, tension beds, drones, pads and atmospheric scoring. - Instant scene generation for fast discovery of new sounds. - Carefully voiced macro controls for shaping mood, depth, motion and character. - Fog control for darker or clearer overall tone shaping. - Halation and Sodium controls for analogue glow, slow evolution and atmosphere. - Spray and Pressure controls for texture and low-end weight. - Full ADSR envelope control. - Hold mode for sustaining evolving drones hands-free. - Built-in on-screen keyboard with octave shifting. - Scene browser for loading, saving and managing custom scenes (presets). - AUv3 support for use inside iPhone and iPad hosts. - Also compatible with Mac devices and supporting DAWs. - Standalone app for direct play without a host. - Designed to produce inspiring sounds quickly without menu diving. Important Information: • Device Layouts The standalone iPhone version and iPhone AUv3 versions are fully optimised for the iPhone screen. The iPad standalone app, desktop version, and AUv3 plugin use a fixed 1:1 interface layout. • Focused Sound Design Dark Park is intentionally designed with a specific sonic identity: cinematic, dark ambient pads and drones. It is not a general-purpose synthesiser and does not aim to recreate every type of synth sound. • Instrument Philosophy Think of Dark Park as a dedicated hardware instrument or soundbox. It excels within its intended palette rather than covering all synthesis styles. • Effects & Processing Dark Park contains no built-in effects. For best results, especially within ambient genres, use external processing such as reverb and delay.
