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. Another usage scenario for Waverley is if you’re just sketching out an idea, perhaps on a less-capable device like your iPhone while you’re on the move.

Release Notes • most moodunits effects now show a parameter in hosts such as AUM for quick tweaks • pre-installed factory sounds have been replace with a "lite" version *** PLEASE READ *** Where did my factory sounds go? Don't worry - those sounds are now available as a FREE download from the MU Store, accessible from the main moodunits app. The "lite" factory sounds are 30 variations of the Saw 1 and Square 1 samples and are all brand new patches. In other words, there are now 80 factory sounds in total! Why did this happen? Prior to this version, every time you updated the app, you were downloading the original factory sounds, and that's a lot of data. With this new version, simply update the app (don't delete the previous version) then download the factory sounds from the MU Store - they're free, you know! Now the original factory sounds are on your device - you don't need to download them again unless you delete the app and its data. Downloading and updating the app is now going to be much faster as it's much, much smaller. Any problems or questions, please let me know via the message form at moodunits.biz - and sorry this isn't a proper site yet. I'm not really a web guy, but moodunits will get its own site eventually. Hope you like the (sort of) new sounds and FX tweaking change! -Rob
