## What is MRT?

MRT7 is a grid-based metronome and drum machine.

- Create basic to complex click patterns on a single grid
- Sequence multiple rhythms across up to 4 grids
- Layer all 4 grids each with a dedicated sound and dynamics — drum machine!

SINGLE, SEQUENCE & LAYER MODES
Single mode — a single grid metronome with fast presets of the most common subdivisions. Customise the grid further with the grid editor.
Sequence mode — configure up to 4 customisable grids to play in any order, with repetitions.
Layer mode — layer the sounds of the 4 available grids to use MRT7 as a drum machine or groovebox.

SOUNDS
Customise 4 sounds: wave-based synthesised clicks, samples of classic drum machines, and real percussion samples. Combine them however you choose.
Control the volume, pitch and tone of each sound individually. Save your favourite sound configuration or reload the factory defaults.

FUNCTIONS (FUNC BUTTON)
- Copy rhythms and/or sounds to another grid
- Swap grids or grid rhythms in Sequence and Layer modes
- Shift rhythms on the grid to create rhythmic permutations — left, right, up and down
- In Layer mode, turn on dynamics to add soft notes to rhythms and grooves

PRESETS & SETLISTS
Load and save presets and organise them into lists. Load a list as a setlist to flick through any of your presets for a gig, rehearsal or practice session.

AUTOMATION
Automate the tempo, shift rhythms, or play timed bells — by time (e.g. every 30 seconds) or by bars/repetitions.

COUNT IN
Choose 1 to 4 bars of count-in before the metronome or drum machine starts.

SHARE AND BACKUP
All presets are shareable using a link or QR code. Back up all your presets, or send a preset and/or setlist to another person as an MRT7 file.

### 5/5 — Not what it seems

*2026-05-11*

Good app overall, but most of the features promised are for pro. The big upset is that is the reason why I got this app in the first place, to have access to a grid-type metronome. It is disappointing that this was the first review, but this is the impression it gave off.

**Developer response:** Thanks for trying the app and leaving a review. It is useful to have your feedback. The grid metronome, custom sounds and dual grids are all free. The 16 and 12 step grids give you a good range of meters to play with too. The PRO version adds more functions like saving, themes, polyrhythms. I hope you get some use out of the free features. If you would like to get in touch at support@mrt7.com I’d be grateful to hear more about your experience so I can improve it for other users. Thanks. Ben

### 3.0.9 — 2026-09-12

PRESET RENAME AND DELETE FIXED
Tapping the pencil or trash icon on a preset was opening the preset instead. Now they work correctly.

FASTER SOUND SELECTION
Sounds now always opens on Sound 1. Tapping the sound buttons on advanced tab now opens their settings directly.

GHOST SQUARE STYLING
Ghost squares on the rhythm grid now show a diagonal hatch instead of an icon, and no longer trigger haptic feedback when tapped or swiped over. Edit Grid's unselected squares also now match the app's button colour in both themes, fixing an issue where they were invisible in dark mode.
