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. ## Key features - Sample-based instrument (Waverley) - 30 factory sounds with tweakable parameters - Basic audio effects (delay, reverb, EQ, etc.) - Light on CPU usage - Access to PDF user guide - MU Store for additional downloads ## Pricing and in-app purchases Base price: $2.99. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | MU Waverley Stringz | $0.99 | one-time | | MU Waverley Mobass | Free | one-time | | MU Waverley Factory | Free | one-time | | MU Waverley Mellopiano | $0.99 | one-time | | MU Waverley Pianoatmos | $0.99 | one-time | | MU Waverley Scapers | Free | one-time | | MU Waverley MegaPortaPad | Free | one-time | | MU Waverley ARC | Free | one-time | | MU Waverley ESC | Free | one-time | | MU Waverley GRANALOG | Free | one-time | | MU Waverley ATMOSPADZ | $0.99 | one-time | | MU Waverley Evoebo | $0.99 | one-time | ## Recent user reviews (10 of 39) All indexed reviews: https://appshunter.io/ios/app/moodunits/id1521447619/reviews.md ### 5/5 — Please update *2025-07-08* Please new packs presets , synth Thanks by your big works ### 5/5 — Mega AuV3 Plugin. Für Ambient einfach perfekt. *2025-04-15* Einige Sounds Moods sind kostenlos, die anderen kosten je 99Cent. Schade dass es kein reduziertes Bundle mit allen Moods gibt :( ### 4/5 — Good *2025-01-26* Initially the expansion packs were not showing but now they are. Beautiful sounds. ### 5/5 — Lil Woodryc *2024-12-30* Rob I think Mood Units could use more effects as options perhaps something like a Caoineag Chorus or something like that to keep the plugin fresh ### 5/5 — Lil Woodryc *2024-11-23* Rob I think Mood Units could use more effects perhaps a glasgow based chorus ### 5/5 — It’s a good plugin but *2024-10-14* Rob I think Mood Units could use more effects perhaps a glasgow based chorus ### 5/5 — Splendid! *2024-03-14* Can’t ask for more for your money or for better sounds. Very nice. Highly recommended. ### 3/5 — Not what I expected *2023-09-20* I was expecting something along the lines of moodscaper or touchscaper with AUV3 compatibility. This is just a shadow of what it could be. ### 5/5 — We need more ❤️ *2022-08-02* Please add more stuff, I just love to use the instruments and FX!

This workaround means that the slider will not update the AudioUnit continuously, when the slider is in motion. ### 1.6.9 — 2025-01-30 Added new Support URL. Added note about IAP downloads. Basically, Apple are no longer hosting new IAP download data and this was a major area where moodunits was intended to grow. Existing IAPs should still work fine, but sadly there will be no more new instruments - what you see in the MU Store is what's available - end of story :-( ### 1.6.8 — 2021-04-11 • reduced download size of main app slightly - sorry it's not terribly exciting, but this has been bugging me for a while ### 1.6.7 — 2021-03-20 • fixed potential issue with Waverley semitone transpose • revised and improved handling of failed / cancelled MU Store purchases If you're still having issues with MU Store purchases, especially after cancelled or failed transactions, please get in touch via moodunits.biz and we'll try and work it out. -Rob ### 1.6.6 — 2021-03-08 • fixed an issue causing delays when switching Waverley presets • Waverley preset sections are collapsed by default (when > 3) on small / iPhone view • removed confusing prompt after purchase restore to download all content when all content is downloaded :-/ Special note for Drambo users: I'm aware of an issue exporting audio when using Waverley inside Drambo. This may be iOS 14 specific and is currently being investigared. Finally, In case you missed the last update, there are new sounds available for MU Waverley as an In-App Purchase: • ATMOSPADZ - Multi-dimensional atmospheric virtual analog pads ## Apps similar to moodunits | App | Rating | Price | Category | | --- | --- | --- | --- | | [StringLab](https://appshunter.io/ios/app/stringlab/id6461312318) | 4.1 (11) | $14.99 | Music | | [MIDI Layers](https://appshunter.io/ios/app/midi-layers/id1640217767) | 4.7 (13) | $6.99 | Music | | [FAC Drumkit](https://appshunter.io/ios/app/fac-drumkit/id1552568814) | 4.7 (83) | $17.99 | Music | | [FAC Clipper](https://appshunter.io/ios/app/fac-clipper/id6742354555) | 5.0 (9) | $9.99 | Music | | [Copperhead](https://appshunter.io/ios/app/copperhead/id6444207037) | 4.7 (18) | $14.99 | Music | | [LayR-Multi Timbral Synthesizer](https://appshunter.io/ios/app/layr-multi-timbral-synthesizer/id1155825562) | 4.5 (95) | $24.99 | Music | ## More apps by Rob Jackson - [moodscaper](https://appshunter.io/ios/app/moodscaper/id1088768073) - [pianoscaper](https://appshunter.io/ios/app/pianoscaper/id1177444402) - [moodscaper SE](https://appshunter.io/ios/app/moodscaper-se/id1247452905) - [touchscaper](https://appshunter.io/ios/app/touchscaper/id1250344299) - [guitarscaper](https://appshunter.io/ios/app/guitarscaper/id1316544251) - [moodscaper LE](https://appshunter.io/ios/app/moodscaper-le/id1435065372) All apps by Rob Jackson: https://appshunter.io/developer/1072346998 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
