Please note: moodunits have been designed as a set of instrument and effect Audio Units. You need to load moodunits into any AUv3 compatible host application running on iPad or iPhone, such as GarageBand or AUM. The moodunits app is not a standalone instrument. *** Please note that this app is now in maintenance / bug fixes only mode as it relies on "deprecated" (by Apple) technology such as hosting *new* IAP downloads. Existing IAPs should work / download OK *** More about moodunits... Waverley is the principal instrument in the moodunits collection. It’s sample-based, but it isn’t a fully-fledged sampling app that allows you to load and edit your own samples. There are already great apps out there that allow you to do that. Waverley in moodunits is pre-loaded with 30 factory sounds, that can be tweaked to taste via parameters that will hopefully be familiar to most of you. However, don’t worry if some parameter names look technical or scary - just experiment! You can’t really “break” Waverley or make “bad” sounds with it. moodunits also comes with some basic effects, allowing you to create a great sounding musical project using just moodunits and your favourite AU host. In keeping with the moodunits design principal, the effects are light on CPU and expose a few essential parameters. They're probably not going to replace your favourite bells and whistles mega reverb or delay, but their simplicity might come as a refreshing change. Currently these effects include a delay, reverb, low-pass filter, 10-band EQ, peak limiter and distortion. Please note: The moodunits app is not a standalone instrument, but can be used to access a detailed PDF user guide and the MU Store for additional downloads. Once you run the app, your moodunits are registered on your device and are ready to be used for music projects in your AU host of choice. For instructions on how to use Audio Units, please refer to relevant documentation for your host, e.g. GarageBand or AUM, etc. Note for advanced users: with the exception of the filter cutoff frequency and resonance in the filter AU, none of the parameters are exposed for automation. Also, please note that the design goals for moodunits is focussed on ease of use, so some advanced users may find the features basic. The screenshots and demo videos online should give you a good idea of what's possible. If in doubt, please ask.

• Enhances Mix Loudness and Adds Harmonic Warmth • Full-Band and Two-Band Clipper in a Single Plugin • Quick, lightweight, and designed for effortless flexibility! • Precise Visual Metering for Fast Peak Control • Knee Curve Adjustment, from Super Soft to Hard • Shape Control of the Harmonic Profile • Dry/Wet Mix for a Natural, Balanced Sound • Low Latency with Optional Oversampling • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Clipper is designed to enhance your mix's loudness and add signature harmonic warmth. While it is based on a similar DSP architecture to the Clip processor in FAC Punchlab, it takes a different approach to clipping control, featuring an advanced user interface with precise metering to track and manage the peaks of the audio signal. The plugin also includes both a full-band clipper that processes the entire spectrum and a multi-band clipper, allowing you to independently clip low, high, or both frequency bands. This provides the flexibility to maintain transparent processing or experiment with creative adjustments, depending on your needs. Built with simplicity and flexibility in mind, FAC Clipper is quick, lightweight, and highly intuitive. The clean, streamlined interface lets you focus on what matters most; controlling the peak levels to maximize loudness while preserving clarity and avoiding the pumping effects often associated with heavily limited signals. Thanks to its precise waveform and level meters, using FAC Clipper is a breeze. Simply add the plugin to your track and adjust the input gain until the waveform meter reaches 0 dB. This gives you a clear view of the signal's dynamic range, making it easier to identify peaks. Next, set the ceiling just below the peaks you wish to control. You can also adjust the Knee parameter for smoother clipping and fine-tune the saturation to achieve the perfect warmth and character. Use the Mix parameter to blend the clipped signal with the original audio, allowing you to control the amount of clipping applied. This helps preserve the natural character of the sound while enhancing loudness and harmonic warmth. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Clipper.html
