moodunits is a set of instrument and effect Audio Units designed for iPad and iPhone. It is not a standalone instrument but can be loaded into any AUv3 compatible host application such as GarageBand or AUM. Developed by Rob Jackson, moodunits offers a range of features and functions that make it a versatile tool for music creation.

The principal instrument in the moodunits collection is Waverley. It is a sample-based instrument pre-loaded with 30 factory sounds that can be tweaked using familiar parameters. Waverley captures the "magic" of analog gear by using samples, providing a unique and authentic sound without the need for CPU-intensive modeling techniques. The instrument also includes sounds with pre-applied effects, allowing users to find ready-to-use sounds without additional processing.

In addition to the factory sounds, users can expand their musical palette through purchases and free downloads from the MU Store, which offers a growing range of conventional and unique instruments. moodunits also includes basic effects such as delay, reverb, low-pass filter, EQ, peak limiter, and distortion, providing essential tools for creating great-sounding music projects.

While moodunits is ideal for iPad music production, it can also be used on iPhones for sketching out ideas or when a desired instrument is only available on iPad. The app is lightweight on CPU and memory, allowing for multiple instances to be run simultaneously. For detailed instructions on how to use moodunits and Audio Units in general, users can access a PDF user guide included within the app.

Please note that moodunits is designed for ease of use, with a focus on providing a straightforward user experience. Advanced users may find some features to be basic, but the available screenshots and demo videos offer a clear preview of what is possible with the app. For any questions or clarifications, users can reach out to the developer for assistance.
