Loop-based mangler effect for creating slowly changing rhythmic sound structures in a deep reverb space from any external signal. Great for experimenting and designing ambient and noise backgrounds with rhythmic elements.

The principle of the application is quite simple. It is based on a loop recorder with two loops. When one loop is recorded, the second is played back. When the loop recording stops, there is a smooth transition between them. Three separate outputs can playback the recorded loop with different pitches (speeds), each with its own effects and two automation generators. The mix of these outputs is fed to the convolution reverb. The reverb is packed with a set of long and deep sound spaces that create a blurry and ambient sound.

But the main feature of this application is its well designed parameters that make it easy to experiment with a huge number of sound options using any source material from live instruments to synthesized sound. With just two parameters you can add complex rhythmic structures based on Euclidean rhythms, and easy-to-use automation generators with a randomize option to add variations to the sound, allowing you to modify parameters like an LFO or based on a given rhythm. The convolution reverb has advanced options with which you can change and extend the original reverb spaces.

Even using the randomization button, in almost every case, you will get interesting and various soundscapes and textures. With this option it is very easy to create the basis of new, unique presets, requiring only slight tweaks to some parameters to get impressive results.

The loop recorder can be started and stopped manually or by input signal, can use fixed length or overwrite the loop while recording, and has the option for crossfade between the end and the beginning of the loop. All this makes it convenient for live use as well as when processing recorded material. As an extended option, you can use a special mode in which the application works as a direct effect, without the loop recorder.

The special panel Sampler is designed for quickly load samples and easy control of the application when used it live. This panel contains the input and output controls, essential controls of the loop recorder, and a large area with a recording counter, which is also used to start/stop the recorder. You can assign up to nine samples for fast loading into the loop, as well as save a recorded loop as a sample and to an external file.

SpaceFields is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). SpaceFields works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, and supports Audiobus and Ableton Link. On macOS, SpaceFields can works both as a standalone application and as an Audio unit (AUv3) with DAWs and audio unit hosts like Ableton Live, Logic Pro, GarageBand, MainStage, Cockos Reaper, Plogue Bidule, Hosting AU, and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a midi learn option), audio unit parameters and importing samples from any directory on device. SpaceFields has a built-in detailed description of all parameters also available as PDF file on application site.

You’ve done it again Igor

There is something about Igor apps that make the so special. They are nothing else like what you see in the AppStore. They are so unique. I can imagine a mad scientist building this Frankenapps and then smiling when they become alive. This is like having Tangerine Dream in my pocket. I lost more than an hour just fooling around with it and I have only scratched the surface. Thanks again for such amazing app. If you are into sound Igor’s apps are a must. 100% recommended. A must have

I opened this app to give it a good run but it’s not that simple. Like all of the apps from this developer, they are well thought out and very deep. I will add more to this review as I learn more within the app. I know this developer is in Ukraine and reviews are necessary to get an app noticed. I will include more information as I use the app in more depth.

The iOS God does it again

Not as esoteric as BeatCutter. I was able to generate instantly interesting/usable loops with this and cannot wait to dig in deeper. Every app by this dev is an event to me and this one delivers. 10/10
