This product is a software synthesizer that supports Audio Units Extension (AUv3). Music software that supports the AUv3 host function, such as GarageBand or Logic Pro for iPad, is required to use this product. DOTEC-AUDIO DeeACID allows anyone to easily enjoy acid bass lines. In addition to a wide variety of sound creation, the level adjustment for overdrive has been auto-adjusted, allowing you to twist the knobs to your heart's content. The UI is specially designed for use with a DAW, and MIDI controller assignments can be made quickly and easily. It also features a variety of visual effects to enhance your enjoyment, so you will lose track of time and become absorbed in the fun! In addition, the phrase generator can generate an unlimited number of phrases according to key, and can also be synchronized with the rhythm track for real-time play! The generated phrases can be saved as MIDI files, so they can be loaded from a DAW and used. By connecting an external MIDI controller and pressing the “Learn” button located below each parameter, you can assign the parameter to the slider of your choice, allowing you to change the tone more intuitively! From version 1.5.0, the DJ Deck mode allows standalone play, and from version 2.0.0, the Ableton Link mode has been added. Now, DeeACID is not just a plugin—it can also be enjoyed as a fully standalone acid bass app! Furthermore, version 2.5.0 introduces brand-new filters and a supercharged phrase generator! From version 2.6.0, improved the oscillators so both Type I and Type II now deliver a thicker sound!

QuadroSphere is a great tool for bringing an instrument to life by creating a soundscape with a constantly moving sound source. QuadroSphere splits the incoming audio signal into 4 distinct coloured frequency bands using the frequency bar. Each band has an associated coloured sphere allowing you to control the pan, stereo separation and volume level. You can use this plugin as a way to impose subtle control over stereo placement with little or no movement, or go crazy with random automation. Adding effects such as reverb or delay on a specific frequency band can help create a lush atmospheric swirling which surrounds the listener. This is great for musicians trying to create minimalistic ambient or tranquil soundscapes. You can create up to 12 snapshots of the sphere parameters and effect settings, then morph between them at a designated speed (measured in beats). You can also enable continuous randomization mode, and have full control over which spheres and control which parts are automated. You can also use QuadroSphere as a stereo splitter, using the additional outputs to add your own effects to band outputs. Key Features: ○ 4 Configurable frequency bands. ○ Control stereo separation, level and pan for each band. ○ Create up to 12 Snapshots. ○ Morph between various panning, width and frequency band levels. ○ Modulation control for automated sweeps around pan center. ○ Convert MONO signals into a pseudo-stereo image. ○ Per band Haas, Delay, Reverb, Chorus and Compressor. ○ Allows combined and individual per-band audio outputs. ○ Continuous randomized morphing of the stereo field. ○ Built in Preset Manager with drag and drop support. ○ Power and Solo for each band. ○ Controlable morph speeds. ○ Various animated transition modes. ○ Access most options using AU parameters or MIDI CC control.
