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!
