Coming from mobile audio app deity Igor Vasilev, SpaceFields is a deep audio mangler effect that just happens to be made for iOS / iPadOS. It’s meant to conjure evolving rhythmic sound structures drenched a cavernous reverb out of any external input. Such effects are great for dissolving samples and recordings into ambient pieces. Rhythmic elements are optional (gotta win the rave crowd somehow).

SpaceFields is based on a loop recorder working with dual 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 at different pitches (speeds). Each output has its own effects and two automation generators. The outputs are mixed and the audio is fed to the convolution reverb, packed with long and deep ambiances. The results sound like mashed potatoes out of hell.

To achieve peak mangling, SpaceFields offers a set of robust parameters for each individual section – Input / Output, Loop, Play 1 – 3, and Reverb. You can add complex movement using an Euclidean rhythm generator, along with automation generators and randomize options for added variation. Likewise, the convolution reverb offer a set of options to change and extend the included reverb spaces.

SpaceFields evades needless complexity with its clearly laid out interface. All main controls are at your fingertips and everything else is available immediately with minimal menu browsing. Kudos to the developer for simplifying a complex effect while leaving plenty of room for tweaking.


If you don’t know where to start, use the randomizer and go from there. There are many interesting possibilities to explore. The loop recorder can be started and stopped manually or from the input signal. It can also use fixed length or overwrite the loop while recording. It also has the option of crossfading between the loop’s start and end points. To further extend SpaceFields’ usability, a special mode is there to bypass the loop recorder and use it as a direct effect.

    Does Spacefields work as a plug in with Reason mac software?
