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.
