Loop-based mangler effect to create slowly changing rhythmic sound structures in deep reverb space from any external sources or samples. 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 options, in almost every case, you will get interesting and various soundscapes and textures. With these options it is very easy to create the basis for new unique presets. It only takes a little tweaking of 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 mode 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, with supports Audiobus host app. On MacOS, SpaceFields can works both as a standalone application and as an Audio unit (AUv3) with DAWs 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 the application site.

TATAT is a MIDI FX designed to create always-changing sequences, to quickly sketch music ideas, to add unexpected events to fixed patterns. If you’re looking for new ways of generating musical ideas, then look no further than TATAT! Set up your parameters, define a mood and listen to an endless flow of notes which you can then record, tweak, and play along to. HOW IT WORKS /// TATAT generates infinite and always changing sequences of notes. You cannot say exactly what TATAT will do, but you can suggest a path to it: by setting up its parameters you can create what we call a mood for TATAT. A mood is a configuration of notes, intervals, time fragmentation, velocity fluctuation, and other factors. Once you set a mood that you are happy with, you’ll listen to an infinite stream of events, always changing, all staying in the mood. 
At this point, according to your needs, you can: - Let TATAT play its stream, and make some intervention to control it: to add silence (Less), to obtain smooth accelerando and ritardando (Ratio), to control how TATAT generates intervals. You can enable Key In function to change notes on the fly. - Add some stability by controlling/automating the Liv/Mem slider, moving between the generated stream and frozen patterns. - Use TATAT to send its notes to enrich (by enabling Thru) existing/incoming MIDI data/parts. TATAT gives you excellent results both with melodic/harmonic and percussive parts! MULTIPLE TIME RES /// Set chance for each time resolution to rule the stream, and scale results with main ratio to create organic time fluctuations. NOTES /// Set chance for each notes to get triggered, enable the keys toggle to change the notes on the fly, giving a different color to the stream. DOUBLE HIT /// Set two intervals and the probability they got triggered, adding harmonic weight to the stream. LET’S PROCESS THE STREAM! /// You can process the generated notes with several parameters: add a velocity variation, a delay, set the length, randomize, and mute some notes. It’s easy and intuitive. FLOW VS PATTERN /// LIV/MEM parameter has a 0-100% range. When is set on 0%, a buffer with given length continuously records the stream; when it’s different than 0%, the buffer got locked, and you set the chance to get live or buffered notes. When you set 100% you always have the buffer content as a static pattern. You add the stability you want to the lunatic stream! 2 FLAVOURS: DARK AND LIGHT SKIN *** Please note: TATAT is an Audio Unit extension (AUv3) – it only works in an AUv3 host app compatible with MIDI FX like AUM, Logic Pro, Cubasis, etc... ***
