Agonizer is a monophonic synthesizer created in partnership with Jakob Haq, a well-known YouTuber and synth bass expert. This app focuses on delivering deep and rich bass sounds that are perfect for musicians and sound designers.

The monophonic synth engine is designed specifically for crafting bass tones. Agonizer offers built-in stereo effects that enhance the overall sound quality. With over 140 factory presets, all finely tuned by Jakob Haq, users can jump right into music creation without starting from scratch. The presets are a great way for both beginners and experienced users to explore various sounds.

One of the standout features of Agonizer is its compatibility with ROLI Seaboard and other MPE controllers. This allows for expressive playing, giving users more creative control. The app supports a variety of connection methods, including USB audio interfaces, wired MIDI, network MIDI, and bluetooth MIDI, making it versatile for different setups.

Agonizer also includes an Audio Unit v3 Extension, which allows for easy integration into your favorite digital audio workstation. Additionally, it features Inter-App Audio support and Audiobus support, offering flexible options for connecting with other music apps. With Ableton Link integration, users can sync Agonizer with other devices seamlessly.

The synth voice of Agonizer is built around dual wavetable oscillators, providing more than 40 wavetables to choose from. Users can experiment with morphing synthesis and X-Mod modulation for unique sounds. The app includes a dedicated sub oscillator and noise source synthesis, adding layers to your audio. The Mangle Section is equipped with controls for pre-filter drive effects and a bitcrush effect, giving users even more sound design options.

To further shape sounds, Agonizer features a VA ladder filter and a wobulator sequenced LFO. This LFO is highly adjustable and can sync to key and BPM, allowing for precise modulation. The app includes variable slope AD envelopes and standard ADSR envelopes to control the dynamics of your sounds. For those who want a bit of analog warmth, a tube-based master drive is also included.

When it comes to effects, Agonizer provides two stereo effect units. Users can add a vintage chorus effect to create lush textures or use a digital delay effect to enhance rhythmic elements in their tracks.

The factory bank of Agonizer includes over 140 presets designed by Jakob Haq. There's a user-friendly preset management system with templates and categories, making it easy to find and organize sounds. Users can even share their presets between the standalone version and the AUv3 version. The ability to export and import presets allows for easy sharing and backup, ensuring you never lose your favorite sounds.

Agonizer is a fully standalone synthesizer app, but it also works as an AUv3 instrument and an Inter-App Audio instrument. This versatility means you can use it in various ways, whether you want to create music directly within the app or integrate it into a larger setup with other music production tools.

To get started with Agonizer, you’ll need an iOS device running iOS 12 or later, ideally an iPad Air 2 or newer. This ensures that you'll have a smooth and responsive experience while using this powerful synthesizer.

In summary, Agonizer is designed for anyone looking to explore synthesis and create rich bass sounds. With its wide range of features, effects, and presets, it's a valuable tool for both beginners and experienced producers alike. Whether you’re performing live or producing tracks in the studio, Agonizer makes sound design accessible and enjoyable.
