Waveshaping Synthesis is a type of distortion synthesis that can create dynamic spectra in a controlled way. In waveshaping, it is possible to change the spectrum with the amplitude of the sound. A simple example of this method is the clipping caused by overdriving an audio amplifier. These simple method creates an astonishing variety of sounds which are very unique and can't be reproduced by any other contemporary synth! microTERA gives you also a method of getting randomly generated sound patches in a way you never experienced before: roll the dice! Every single try gives you a new unique sound patch, really every try, promised… Waveshaping Synthesis • Wavehaper with user programmable shape • Spectral shape specification • Three sine oscillators • Feedback input for noise components • 4 Low frequency oscillators • 4 Envelopes with tempo sync • 64 time/level segments per envelope • Monophonic or polyphonic with 16 voices. • Over 150 factory sounds • Uses programmable sequences with up to 32 steps. • Can trigger single notes and chords. • Unique randomizer generates Arpeggios with 100% usability. • 32 Arpeggios included, unlimited useer arpeggios possible. • For each step you can program tie, accent, transposition and note order Effects • Chorus • Phaser • Distortion (Tape/Tube/...) • Echo/Delay • Reverb Global • Audiobus compatible (Input slot) with state saving • Support for Ableton Link. • Inter App Audio compatible. • CoreMIDI / Virtual MIDI • Audio recorder with Metronome. • Upload to SoundCloud and File Export. • Audio pasteboard.

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.

Verdict
The clearest difference is price: microTERA at $1.99 against SpaceFields's $10.99. microTERA also leads on rating (4.9 vs 4.7) and iOS requirement (11.0 vs 13.4). SpaceFields's advantage is update cadence (every 2 months vs every 4 months) and ratings volume (47 vs 8). On ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
microTERA costs $1.99 and SpaceFields $10.99 up front. Neither carries in-app purchases, so what you see is what you pay.
microTERA holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: SpaceFields has 47 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 81% of microTERA's written reviews are positive against 90% of SpaceFields's, so the app with the better star average is not the one people write more warmly about.
microTERA ships an update every 4 months, SpaceFields every 2 months. The most recent releases landed on September 17, 2026 and September 27, 2026 respectively.
