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.

sqsl Latch
This app is a conceptual MIDI controller and sequencer for creating drone, textural, and soundscape synthesizer patches. It allows for sending MIDI notes, pitch bend, and CC values with advanced looping and parameter modulation features. Save and recall your setups for later use.
- MIDI note, pitch bend, and CC output
- 16 groups with assignable MIDI channel and color
- 8 assignable Continuous Controllers per group
- Looper for recording and shuffling note phrases
- Adjustable phrase playback speed and synchronization
- Parameter modulation via internal randomizer
- Smooth parameter transitions with LAG control

sqsl Latch is a conceptual MIDI controller and sequencer designed for working with evolving drone, textural or soundscape synthesizer patches. It can send out MIDI notes, pitch bend and CC values. There are 16 groups split into 2 banks (a, b, c, … p). Groups have assignable MIDI channel, color and 8 Continuous Controllers (CC). When user touches one of the pads, note is activated and is held on until new touch (on the same pad) is registered. Left slider controls the velocity of note to be activated. Every group has a looper able to record note state changes - phrases. Order and velocity of recorded notes is automatically shuffled after phrase restarts (can be optionally prevented by activating group’s LOCK button). Phrase playback speed is adjustable (CLOCK and DIVIDER parameters). Phrase can be synchronised - set to restart automatically with previous group's loop. Synchronisation can be set to happen on every pass, every second, third... up to 16th and can be set to be ignored randomly (probability setting 0-100%). Group parameters can be adjusted using sliders or modulated by internal randomiser with adjustable range (RANGE and RANGE 2 parameters) and speed (per group LAG control - left-most slider). Apart user definable CCs, each group has following MIDI parameters: MOD (mod wheel), BEND (pitch bend), VOL (volume), EXP (expression), PAN (pan), FOOT (foot controller), TOUCH (aftertouch/channel pressure). Group parameters related to phrase playback are: CLOCK (resolution and playback speed), SYNC with divider (loop synchronization), NOTE SKIP (randomly skipping notes events 0-100%), SYNC SKIP (randomly skipping sync events 0-100%), DIVIDE (integer group's CLOCK divider), LOOP (loop or one-shot setting), SHIFT (degree offset with selected scale). LAG can be applied to parameter changes - when new value is selected, change does not happen immediately but value is transitioned smoothly based on LAG time (left-most slider). Setup setting (CC numbers, channels, colors, and MIDI output) are saved and recalled when app is restarted. Loops, CC values, parameters and their modulation states can be written to preset positions for later recall. For detailed description visit https://www.seqsual.com/latch Important notes: - Latch does not make any sounds on its own, it generates MIDI messages (notes, pitchbend and CC values). - Latch does not synchronise to incoming external MIDI clock. - Latch was designed for full-size iPads and is not recommended for iPad Mini users.

Verdict
The clearest difference is rating: SpaceFields at 4.7 against sqsl Latch's 3.7. SpaceFields also leads on price ($10.99 vs $19.99) and review sentiment (90% vs 67%). 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
SpaceFields costs $10.99 and sqsl Latch $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.
SpaceFields holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: SpaceFields has 47 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 90% of SpaceFields's written reviews are positive against 67% of sqsl Latch's.
SpaceFields ships an update every 2 months, sqsl Latch every 5 months. The most recent releases landed on September 22, 2026 and September 9, 2026 respectively.
