This audio effect filter is a hybrid between a simple reverb and a very complex delay. R0Verb consists of up to 50 separate delay lines, and puts you in charge of every single delay with controls for volume, pre-delay, feedback & high shelf. It can be used for everything from simple delays to complex spaces, whatever your mix needs. It also has a nice Randomizer if you're feeling lucky!


• Up to 50 parallel delays*

• Every delay has parameters for volume, pre-delay, feedback, delay time & a high shelving filter

• Randomizer - creates a space with user-defined bounds

• Multi-select and edit several delay-lines in one gesture

• Post 3-band EQ

• IAA and Audiobus2 compatible

• Comes with a few factory presets for inspiration

• Load / Save user presets

• Remember IAA hosts (will automatically load last used settings when a host reconnect)

• Documentation

* When using a lot of delay-lines this app consumes quite a bit of CPU. If you experience audio glitches and stuttering we recommend reducing the number of active delay-lines. iPad 2 or later is recommended, iPad 4 or later is preferred.

A simple single cheap AuV3 version

Innovative design and simplistic interface

You guys over at Klevgränd Produktion have some really great designs and concepts. I have limited myself to just using 'SquashIt' thus far, simply because I am really leaning back in to using my iPhone primarily for music production on the go (my iPads 2 and 3 have seen better days), and I mostly see myself using my iPhone 6 plus for a year or two, i maxed out the specs on my iPhone 6 plus with the 128gb model and love everything about it. I dove in with 'SquashIt' mostly because it's universal and has a osx plugin that work in an identical fashion. I would buy every last one of your plugins if they had identical vst/AU's for osx. I picked up ROverb because you are offering a desktop version of the same for a reasonable price, but I'm holding off purchasing the vst until I get a better idea of how ROverb sounds.... problem is, my iPad 2 running ios 7.12 and iPad 3 running 8.12 have performance issues with this app and some of the newer apps that have come out (DFX, Z3TA+, Tera Synth, Voltan Telepathy, just to name a few) just do not run well on my older (in computer years) iPads. ROverb is not an exception to this trend, more than a 6 or so points on my iPad 2 with audiobus or interapp audio running. So if you were to make these universal I would hop right on your bandwagon. But I'm going to give it a shot after fulling rendering a track and then processing it through ROverb without audiobus or anything else running to get a better feel for it. But I will say what I have gotten to work successfully, sounds absolutely amazing. I really love the concept and look forward to using this in the future. More than likely i will buy the VST/AU, but I do just want to spend a little more time with it in case ... well in case whatever. No joke make your apps universal, I will buy them. The only reason i have not pulled the trigger on SyncMix is because I cannot tell if it's a dead project or not... not enough reviews data ect. to make an informed decision. I looks really useful though.

Back to ROverb, I'm a huge fan of randomizations, isomorphic patterns, algorithmic music making ect. and your random for ROverb is really good at being random within the defined constraints. That's not always so easy to find in an app, you guys nailed it I think. More random is on my wishlist for just about every music making app in the App Store.

Bottom line, if you have a newer iPad I wouldn't hesitate buying this app if your into these type of effects. If you can deal with the limitation on an older iPad like mine, it's really good so far in my opinion. I hope you guys do well with this app and really everything, because you are just nailing the concept I'm interested in for apps working between mobile and desktop studios with SquashIt and ROverb. Moving presets between ios and desktop VST's/AU's is the place I'm aiming for here (much like what Sugar Bytes is doing right now with their apps). 5 out of 5 for sure on both ROverb and SquashIt.
