Features & Capabilities

One Loop is a 10-track loop-station designed for singers, songwriters & instrumentalists. Whether you want a personalised backing track, or need to record an idea for your next big hit, One Loop brings performance and recording straight to your phone.

Features: • Simple, easy to use looping. • Built-in studio quality effects: Noise Gate, EQ, Compression & Reverb. • Advanced layer control and grouping. • Metronome selection with a variety of backing percussion. • MIDI support and mappable control for hands free performance. • Supports external audio interfaces; up to 8 channels of audio input.

Recording

Whether you choose your device’s built-in microphone for quick and easy use, or an external interface for multiple routing options, One Loop encourages portable creativity. Don’t be restricted by the limitations of a computer when all you need is your phone… and something to record!

Enjoy the app’s seamless looping and build up to 10 beautiful layers with ease. Save your projects for later reference, you’ll never forget those 3am ideas ever again! Make sure to wear headphones for clean recordings with no feedback issues.

Complete Control

One Loop gives you complete control to form your best ideas. Each layer is mute-able and has an adjustable volume slider to shape your overall sound. Assign each layer to a bank of 4 groups (A to D) for quick variation of instrumentation, or different sections of a song.

Setup your Bluetooth or USB midi devices and assign their parameters to trigger any of One Loop’s functions for greater control and smooth performances.

Manage Your Mix

One Loop gives you the controls to refine your recordings with studio quality effects designed by audio engineers: Noise Gate, EQ, Compression and Reverb.

Wherever you’re recording, either in a quiet room or a busy outdoor environment, you can reduce any unwanted noise by adjusting the Noise Gate’s threshold and envelope, to create cleaner recordings.

Boost or Cut the Input’s EQ frequency bands (Low, Mid and High) with a +/- 15dB range to shape the sound of your loop layers.

Adjust the acoustic environment of your mix, from a small garage to a large cathedral, by changing the size & effect percentage of the Reverb.

Settle a busy, complex layered mix using the Bus Compressor’s threshold and ratio controls.

User Reviews

Users broadly praise One Loop for its straightforward, easy-to-use interface, a polished GUI, and a strong live-looping feature set with rich metronome options and MIDI mapping. However, recurring problems include stability issues—crashes and freezes during loading or when accessing saved loops—which appear across multiple reviews. Several users also want better interoperability (Audiobus/IAA) and continuous improvement on workflow features, such as loop trimming, deletion, buffer length control, pan/mono handling, and a more consistent UI. A number of reviews also note the value of upgrading and the app’s overall enjoyment when it runs smoothly.
Pros
  • Easy to use / intuitive UI
  • Rich metronome options
  • Nice GUI / polished design
  • Solid live-looping features with MIDI mapping and built-in effects
  • Good value when upgrading / generally enjoyable
Cons
  • Stability issues: crashes and freezes during load, and trouble accessing saved loops.
  • Missing inter-app audio integration: no Audiobus/IAA support as many users expect.
  • UX/feature gaps: needs loop trimming/deletion, buffer length control, pan options, solo/mute improvements, and UI design/readability refinements.

Love the app but it won’t let me upload any of my songs and the app crashes. Unfortunate…

No matter what metronome selection combinations, you try, the metronome always got recorded over and over again during looping and built upon itself and just got noisier and noisier
