Klevgränd effects app roundup – including the new Røverb app

The developers at Klevgränd Produktion have been creating some of the most interesting effects apps of late, and have just released their latest, called Røverb. Røverb is a reverb/delay app, but like all apps from Klevgränd, it's not "just" a reverb or delay app.

For anyone who has been reading my reviews, you'll know that I'm a huge fan of the Holderness Media and Kymatica effects apps. Anything these guys create, I'm all over it. I would have to include the guys at Klevgränd in that category as well. Small in file size, incredibly affordable in price, I'm definitely going to be anticipating whatever comes next from Klevgränd.

OK, on to the apps!


Røverb is the latest creation, and is a sort of hybrid between a reverb app and a delay app.

As with the other Klevgränd apps, the interface is one screen, simple and elegant. Eschewing dials or numbers, you are met with a large semi-circle covering most of the screen. Within this semi-circle will be where most of the action happens. You'll see right away lines radiating out from the center, with two dots on each line. These dots represent the decay and gain, and the space between these dots (which can be moved by selecting the icon with the four points coordinate looking thing) are the decay time and the pre-delay time. The lines can be pointed in any direction, which corresponds to the panning of the output sound.

There are various parameters that can be adjusted here. For instance, the size of each circle represents the high shelf filter (adjusted by the sloped lined icon). You can adjust the volume by selecting the "bars" icon, and adjust each of the lines. You can add up to 50 lines, so there is some pinpoint control that you can adjust here.

The app does come with six presets to get you started. It also has a sweet Randomizer, which will randomize the lines based on the four settings: Tail Time, Room Size, Predelay, and Complexity. Along with the Randomizer are controls to adjust the EQ and the Wet/Dry output. As a departure from their other apps, Røverb actually comes with a brief manual included as well.

Svep is a beautiful combination of Phaser, Flanger, and Chorus. As I'm a sucker for all three of these effects, this app is a new favorite of mine.

Once again, Klevgränd goes with the minimalist interface approach, and once again it works. One screen, that's it. Two large circles control the left and right output. As with a few of the Holderness Media effects apps, these can either be linked or separated. I love this idea. Obviously, syncing them gives you a nice stereo output (which can be adjusted with a slider to control how much stereo or mono you want it to be). But de-coupling these really allows you to get some interesting textures. For instance, leaving the left channel fairly straight forward, and putting some modulation on the right channel really throws your ear a curveball.

Adjusting the wet/dry output is done by a simple slider. To adjust the output of each side, you use the controls on the outer ring of each circle (slide your finger up or down outside of the circle) What isn't so simple is the adjustment to the modulation. The actual action is simple, but the effect is anything but simple. Dragging from the center "+" of the circle, either up/down or left/right is where the magic happens. Left/right seems to control the frequency, and up/down seems to control the output, but since there's no manual I'm kind of guessing here.

The beauty of this app (along with the others I'll discuss) is that they are built for playing around until you find what you like. No dials or numbers to specifically set your settings. Some folks might not like this kind of wildness. I love it. Built for experimentation, you can really have some fun with Svep.

I love distortion. I don't know why, but it just works for me. SquashIt is an app that takes distortion, and gives you control over where that distortion is. As a multi-band distortion effect, you can set the levels for the low, midrange, and hi end of your sounds. I may be wrong, but I don't know of another iOS effects app that does this.

The controls couldn't be easier. Two big dials for the input and output. Three large columns representing the lo, mid, and hi. Drag the levels up for more distortion, down for less. I told you this was easy! But, you can also adjust the range of each section by dragging horizontally to increase or decrease each column. I love that I can add some distortion on the low end, for instance, and let the rest come through clean. Or, if you want to add a bit of grit to the high end of your guitar solo, easy peasy lemon squeezey.

OK, first off. Greatest name for an app, ever. Seinfeld fans will get the reference, and if not their demo video lets you in on the joke,

If you didn't get it from the video above, Vandelay is a multi-band delay app. Much like SquashIt, you can adjust the levels of the low, mids, and high end individually. I freakin' love this. Subtle to crazy, you can do it all in Vandelay.

Again, simple interface meant to be explored and tweaked. Wet/dry mix and BPM sync can be adjusted by large dials on the left side of the screen (as with the others, just one screen). Dominating the screen are three horizontal rows (you've probably already guessed what these are for). Each section can be muted, and the output for each section can be adjusted by a small horizontal bar on each row.

Here's where the fun starts. Within each row are two different control points - one for the modulation and one for the delay time. This last one can be moved around to set the time. The first one can adjusted up or down to control amount and frequency of modulation. This is where things can get crazy quick. You can get some very warbly sounds, if that's what you're going for. It does produce a neat effect, to only modulate one section, and bring the output down low, but really twist the heck out of it. It can present a very quiet, almost hidden sense of discomfort to an otherwise "nice" track.

All of these apps from Klevgränd are so tactile in nature. They take advantage of the iPad screen in ways that many apps fail to do. In order to fully appreciate these apps, you'll need to experiment a bit. There isn't any hand-holding here. With the exception of Røverb, there are no manuals. When you open the app, you might say to yourself, "Now what?". But in my mind, that's the beauty of what Klevgränd is doing here. They are giving you the paint brushes, but not telling you how to paint. That is for you to decide.

From a technical standpoint, these apps are all Audiobus and Inter-App Audio (IAA) compatible. They are all very small in file size. And, they are all extremely affordable. For the price of a mid-sized iOS synth, you could own all four of these effects apps. If you're looking for something that might be just a little outside the norm, this suite of Klevgränd apps will definitely be your thing.
